INTRODUCTION

The Model 3005 is an ergonomic, lightweight instrument which can be used for measurements of gamma radiation levels up to 50.0 mSv/h (5.00 R/hr). The Model 3005 features the ability to measure radiation in count rate, exposure rate/dose, activity rate, time-averaged rates, and scaler counts. The instrument features a large backlit LCD (liquid crystal display), an easy, intuitive use keypad, and audio feedback. The unit body is made of lightweight but durable plastic. It is intended for outdoor use and can resist splashing water. The foam grip provides a comfortable, ergonomic grip but may be removed for ease of decontamination.
Three modes of operation are available for the Model 3005 – RATE, MAX, and COUNT.
RATE mode operation will display the current count, exposure, or activity rate.
MAX mode is used to capture the highest count, activity, or exposure rate detected – useful for finding a peak rate, or frisking when the display is not visible. Two sets of units (primary and secondary) for RATE and MAX modes can be chosen from among cps, cpm, Bq, dpm, R/h, or Sv/h. The user can switch between these two units by simply pressing the UNITS button.
COUNT mode allows the user to perform a count for a predetermined time. Depending on the count units chosen, the result can be a scaler count (in counts or disintegrations), a time-averaged rate (cpm, dpm, Bq, cps), a time- averaged exposure or dose (R/h, Sv/h), or an integrated exposure or dose (R or Sv). The primary keypad includes four push buttons: ON/OFF to toggle instrument power, UNITS to change between available units, AUDIO to change audio levels, and MODE to switch between available modes.
The standard handle includes a LOG button that allows the instrument to log up to 1000 data points when activated with the optional Lumic Datalogging Kit. The display will be automatically back-lit if light levels are low or can be set to a user defined light level. The display back-light can also be configured for “Continuous On” operation. RATE, MAX, and COUNT modes can be silent or utilize a “click” audio; the “click” audio is always silent during COUNT mode by default. A “sigma” audio mode can be enabled (disabling the “click” audio) in RATE and MAX modes when scintillator detectors are used, and this mode makes it easy for the user to find small increases above the background radiation level. In this mode, the instrument measures background for 8 seconds after power-up, and then beeps whenever the rate increases by a small amount. Users are freed from watching the numeric value to “find” something. They can simply listen for multiple beeps. Setup of the instrument is accomplished through the front-panel buttons, or through Lumic 2.0 software available from Ludlum Measurements.
Front-panel setup can be disabled via the internal switch on the Model 3005 in order to protect settings from inadvertent changes. When the settings are protected, the user can view the settings or modify a limited number of settings as defined with the Lumic software. Using the Lumic software, the Model 3005 can be configured to allow changes to the alarms and/or count time even when in protect mode.
The unit is operated with four alkaline AA batteries for operation from -20 to 50 °C (-5 to 122 °F). Battery life is approximately 750 hours (as low as 100 hours w/backlight always on) under normal usage. A low-battery indicator on the LCD warns when less than 16 hours of battery life remain. The Model 3005 may optionally be provided with a 1/8-inch stereo headphone jack that would allow for headphone use for audio output. It is located near the left handle base.
If a headphone jack is not in use, the Model 3005 may optionally be provided with an RS232 serial output for connection to PC or other electronic device. For more advanced use: See Appendix A for information on our Auxiliary Communications features, which allow the instrument to expand its capabilities with a variety of external devices through a standard serial interface.

GETTING STARTED

2.1 Unpacking and Repacking
Remove the calibration certificate and place it in a secure location. Remove the instrument and ensure that all of the items listed on the packing list are in the carton. Check individual item serial numbers and ensure calibration certificates match between instruments and detectors (if applicable). The Model 3005 serial number is located on a label on the front side of the unit.
To return an instrument for repair or calibration, provide sufficient packing material to prevent damage to the instrument during shipment. Every returned instrument must be accompanied by an Instrument Return Form, which can be downloaded from the Ludlum website at www.ludlums.com. Find the form by clicking the “Support” tab and selecting “Service Department” from the drop-down menu. Then choose the appropriate form located under
the “Returned Goods Form” heading.
2.2 Battery Installation
A low-battery indicator appears at the top of the LCD when less than 16 hours of battery life remain. When this indicator is present, follow these steps to replace the four standard AA batteries:

1. Turn off power to the instrument.
2. Turn the instrument over so that the bottom of the instrument is facing up.
3. Use a straight, medium-sized screwdriver to turn the single screw on the battery cover one-quarter turn counter-clockwise.
4. Release and remove the battery cover.
5. Replace all four AA batteries.
6. Replace the cover and turn screw one quarter of a turn clockwise to secure.

2.3 Instrument Operational Test
Once this procedure has been completed, the instrument is ready for use.
2.3.1 Turning the Instrument On
Turn the instrument ON by pressing the ON/OFF button for about a second, and then releasing.
The instrument should activate all the LCD segments and the audio. Observe the device during this time. If any LCD segments are missing, or audio fails to work, the device is in need of repair. Please refer to Figure2.1.

Figure 2.1: Startup Display (All Segments Shown)

The instrument then displays the firmware version. Please refer to figure below.

Figure 2.2: Firmware Version Display

Note: Firmware versions with Bq units are equipped with auxiliary communication.
Beginning with the n42 version firmware, the tick marks below the firmware number define the board generation which will help with future firmware updates. Once n42 is installed, the user will no longer have to open the instrument to determine which version of the main processor board was used in the instrument. Instead, use the following table to determine which main processor board is installed in the instrument:

• 1 tick – 5498-612
• 2 ticks – 5519-091
• 3 ticks – 5519-779

The instrument then displays the battery voltage. Please see Figure below.

Figure 2.3: Battery Voltage Display

The instrument then displays the number of stored records if datalogging is enabled. Please refer to the figure below.

Figure 2.4: Startup Display Showing 189 Stored Data Records

The instrument will then move to normal operation, displaying the current rate for the Primary units (factory default: mR/h). This boot-up process takes about 5 seconds, plus another 8 seconds if Sigma Audio is enabled.
If the Sigma Audio option is selected, the unit will display a countdown from :08 to :01 (in seconds) as the unit measures background radiation levels.
Ensure that the low-battery indicator is not present. If the low-battery indicator is present, replace the batteries as soon as possible. Should the instrument detect a battery voltage that is high enough to power on, but too low to safely operate, the display will blank and the lowbattery icon will flash. Normal operation will not be available until the batteries have been replaced. Under extreme low-battery conditions, be aware that the unit may not even turn on or may turn itself off abruptly.
To assure proper operation of the instrument and detectors(s) between calibrations, an instrument operational check including battery test and instrument test should be performed at least daily or prior to use, whichever is less frequent. A reference reading (or readings) with a dedicated check source should be obtained with the detector(s) in a constant and reproducible manner at the time of calibration or at the time the instrument is received in the field.
If at any time the instrument fails to read within 20% of the reference reading when using the dedicated check source, it should be removed from service and sent to a calibration fa-cility for recalibration and/or repair. If desired, multiple readings may be taken at different distances and/or with different sources so that other scales are checked.
Example of a Check Source reading:
Check Source #…………….
Rate…………………….
Units………………….

2.4 Sigma Audio
The Ludlum Model 3005 has the standard “click” audio that is widely used by radiation instruments; however, it also has a Sigma Audio mode that can be enabled to change the audio sound.
In the sigma audio mode, the instrument measures the background radiation for eight seconds on power-up, and then automatically sets a low threshold alarm rate above the background rate. Afterwards, the instrument will produce a beep any time that the instrument “sees” more than this threshold value. The user doesn’t need to watch the display to find a small increase over background; the user may just listen for multiple beeps. Thus, the unit has an audio alarm that, on power-up, adjusts to just above the current background level and provides a sensitive audio indication to the user.
Note that this audio alarm can also work in conjunction with the fixed alarm, i.e. the user can have both a floating audio alarm (resulting in audio beeps) based on the background level, and a fixed tone audio and a steady ALARM icon when a predetermined fixed alarm level is exceeded.
2.5 Detector Failure Diagnostics
Note that the Model 3005 has its own diagnostic tests to ensure that the detector is functioning correctly.
2.5.1 Detector Loss of Count
If the detector stops detecting radiation for a settable number of seconds, the Model 3005 will flash the minimum display value to indicate which units have been affected by the loss of count event. This indication is common if the unit is powered up without a detector connected. If this indication is observed with a connected detector, remove the unit from service and have it evaluated by a qualified repair and calibration technician.

Figure 2.5: Detector Loss of Count Display (Display Will Flash)

2.5.2 Detector Over Range
If the detector is exposed to high levels of radiation or has an internal malfunction that causes it to count high or excessively, the unit flashes the maximum display value for the currently selected units as a warning. Additionally, the ALARM icon is displayed at the top of the screen, an audio alarm sounds (which can be silenced by a long press of the ON/OFF button ), and the device status OVERRANGE is streamedor logged. The user should ensure whether this condition is being caused by a high radiation field, by a shorted cable, or by internal malfunction. If a Maximum Display parameter is set, then it is possible for the display to flash the Maximum Display value under this condition.

Figure 2.6: Detector Over Range (Display Will Flash)

2.5.3 Detector Overload
As another diagnostic test, the Model 3005 monitors the HV supply’s detector current. A current overload threshold can be set via Setup Mode or Lumic Software. (A setting of 0 disables this alarm.) In general, this alarm setting can be used to detect when there is some detector failure, a cable failure, or a possible high level of radiation. When this alarm is triggered, the LCD will display “OL” in place of the numerical values, and an alarm tone will sound. Once the detector current goes below the threshold, the Model 3005 will return to normal operation.

Figure 2.7: Detector Overload Alarm (Display Will Flash)

2.6 Instrument Use And Controls
With four front-panel buttons and one handle button (as seen in front-panel drawing in front of manual), the Ludlum Model 3005 offers many features in a small package. Each button may be pressed and held for a predetermined length of time, signified by instrument beeps, to access unique instrument features. As the button is pressed, the instrument will beep to indicate the user has reached a new level of button access.

• A short press and release, less than 1/2 second and before any instrument beeps occur, will activate the first level of button operation. When the button is released, a single beep will occur as an acknowledgement.

• A long press, greater than 1/2 second but less than 2 seconds, will force the instrument to emit one beep. Release the button after the beep to activate the second level of
  operation.

• An extra-long press, greater than 2 seconds and after the second instrument beep, will activate the highest level of operation. After the second beep, the button may be released.

By default, the majority of functions are assigned to short presses of the buttons.
2.6.1 ON/OFF Button:
Used to power the Model 3005 ON and OFF.

• Power On: Press for approximately one second and release.
• Power Off: Press and hold for approximately five seconds. The display will show a 3, 2, 1 countdown after the second beep. Releasing the ON/OFF button during shutdown will return the device to the previous state of operation. At completion of the shutdown count, the LCD will go blank (unless a USB cable is connected in which case the USB icon will flash).

Short Press (press and release before one beep):

• During normal operation, it will acknowledge/silence alarms in any mode of operation.
• Change Log Location selected position (If data logging mode 2 is enabled).
• Will move selection position in the device menu.

Long Press (press and release after one beep):

• In RATE mode, it will reset the currently displayed rate if the user has permission (permission set from Lumic 2.0 software). The minimum display will be shown before returning to the exposure rate.
• In RATE mode, when Sigma Audio is enabled, the instrument will take a new background reading and update the Sigma Audio level.
• In MAX mode, it will reset the current MAX value.
• In COUNT mode, it will:
  • If COUNT mode is ready: It will initiate the count.
  • If COUNT mode is in progress: It will stop the current count and reinitialize the instrument to begin the next count.
  • If COUNT mode is complete: It will reset the count mode and reinitialize the instrument to begin the next count.

Extra-Long Press (press and release after two beeps):

• Currently has no effect.

2.6.2 UNITS Button:
In default operation, the display shows the current exposure rate using the Primary units. A short press of the UNITS button (1 beep) will switch between Primary and Secondary units.

The Mode button’s primary function is to switch between available enabled modes.
Short Press (press and release before one beep):

• During instrument initialization and within 4 seconds after the power-up screen, three short presses of the MODE button will place the instrument into setup mode. Once the instrument is displaying normal operation, and 4 seconds have passed, the button can be used to advance to the next available mode.
• Used to advance between the three operating modes: RATE, MAX, and COUNT. While RATE must always be enabled, any combination of MAX and COUNT modes may be disabled from use.

Long Press (press and release after one beep):

• Currently has no effect.

Extra-Long Press (press and release after two beeps):

• Enables/disables the Auxiliary Communications in conjunction with the UNITS button.

2.6.5 LOG Button:
By default, the LOG button’s primary function is to log an event or initiate a count in COUNT mode, which will be logged upon completion of the count (if data logging is enabled); however, the functionality of the LOG button can be configured in software to permit multiple functions to be assigned to the LOG button. This is referred to as Button Mapping. For more information on Button Mapping, please refer to Section7.9. The default operation of the LOG button is as follows:
Short Press (press and release before one beep):

• In RATE mode, it will log the current rate reading if datalogging is enabled.
• In MAX mode, it will log the current MAX value if datalogging is enabled.
• In COUNT mode, it will:
  • If COUNT mode is ready: Initiate a count. Upon completion, the result will be logged if datalogging is enabled.
  • If COUNT mode is in progress: Button has no effect.
  • If COUNT mode is complete: Button will log the current result.
• If datalogging in Mode 2 and a log event has been initiated, the button is used to accept the current location ID.

Long Press (press and release after one beep):

• Currently has no effect by default.

Extra-Long Press (press and release after two beeps):

• Currently has no effect by default.

2.7 RATE Mode Operation
In RATE mode, the current count/exposure rate will be displayed. The maximum displayable value, regardless of units, is 999 k.
If an alarm is not in progress, a long press of the ON/OFF button will reset the averaged rate before releasing the button. The Reset feature must be enabled through Lumic 2.0 Calibration software and will be disabled when Sigma Audio is enabled.
A short press of the UNITS button will switch the displayed value between the Primary and Secondary Units.
A short press of the AUDIO button will toggle click audio between Off and On (Hi). When Sigma Audio is enabled, a short press of the AUDIO button will toggle the Sigma Audio volume levels.
If an alarm condition is present, a short press of the ON/OFF button will acknowledge and turn off the alarm audio. Under an alarm condition, the ALARM display indicator will be activated. There are two user settable alarms for both the primary and secondary units. If both alarms for a particular unit are set, the first alarm will activate beeping alarm audio and a flashing ALARM display indicator; If only one alarm is set or the second alarm is triggered, both the alarm audio and the ALARM display indicator are continuous. Alarms are nonlatching in RATE mode.
When Sigma Audio is enabled, and an alarm condition is not present, a long press of the ON/OFF button will reset the Sigma Audio alarm level. The Sigma count can only be reset in RATE mode. If sigma audio and device rate reset are both enabled, the device rate reset will automatically be disabled.
If other operational modes are available, a short press of the MODE button will move to the next available operational mode.
By default, a short press of the LOG button, if datalogging is enabled, will log the currently displayed rate.

Figure 2.8: RATE Mode Displaying Background Radiation Rate

2.8 MAX Mode Operation
While in MAX mode, the highest detected count rate (since MAX mode was selected) is displayed. The word MAX will be displayed when in MAX mode. A short press of the UNITS button will switch the displayed value between the Primary and Secondary Units.
A short press of the AUDIO button will toggle click audio between Off and On (Hi). When Sigma Audio is enabled, a short press of the AUDIO button will toggle the Sigma Audio volume levels.
Under a non-alarm or alarm condition, a long press of the ON/OFF button will reset the display. When Sigma Audio is enabled, the Sigma Audio alarm level cannot be reset in Max Mode.
If an alarm condition is present, a short press of the ON/OFF button will acknowledge and turn off the alarm audio. Under an alarm condition, the ALARM display indicator will be activated. There are two user settable alarms for both the primary and secondary units. If both alarms for a particular unit are set, the first alarm will activate beeping alarm audio and a flashing ALARM display indicator; If only one alarm is set or the second alarm is triggered, both the alarm audio and the ALARM display indicator are continuous. Alarms are latching in MAX Mode. Under an alarm condition, the ALARM display indicator will remain on until the display is reset.
If other operational modes are available, a short press of the MODE button will move to the next available operational mode. By default, a short press of the LOG button, if datalogging is enabled, will log the currently displayed MAX value.

Figure 2.9: MAX Mode Display With ALARM Indication

2.9 COUNT Mode Operation
When entering COUNT Mode from another operational mode, the currently selected COUNT Unit will be displayed for approximately one second. The purpose of COUNT mode is to count for a predetermined amount of time, and to display the results on the display. Predefined count times of 6 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, and 10 minutes are available as well as a user- defined count time and continuous counting operation (count time displayed as 0 or the minimum display). The maximum user-defined count time is 600 seconds or 10 minutes (9:60). The maximum displayable value, regardless of units, is 999 k.
Count mode operation is very flexible, depending on the units chosen. A common choice is for the count mode to just perform a scaler count for a specified time, with a resulting answer in counts (equaling detected radiation events).
There are three different options for COUNT mode, which can be set through software.
Go to “Cnt Display Mode” in the Dev tab. Select the desired option:

• Timer: Will only show the countdown timer while the timer is active (default selection).
• Readings: Will only show the current gathered reading.
• Timer/Readings: Will cycle between showing the countdown timer and the current reading.

****By default, a short press of the LOG button will start a count and automatically log the result if datalogging is enabled. An extra-long press of the UNITS button during the count will toggle the display between the timer and reading.
Sigma audio is completely disabled in Count Mode. Audio ‘clicks’ are disabled in COUNT mode by default but may be enabled thru software (see Lumic 2.0 software parameter DevCnt-Audio Mode). Adjusting Dev Cnt Audio Mode will enable or disable the click audio during a COUNT.

• Off – always off
• On – always on
• W/Count – audio is only enabled during an active count

If a result in terms of activity is desired, the scaler count can also be in units of “d” or disintegrations. But if the count units are chosen to be cpm or cps, then the resulting answer is an averaged count rate over the time interval. Similarly, if count units of Bq or dpm are chosen, the resulting answer is an averaged disintegration rate.
If the user desires the instrument to show results in terms of disintegrations/area (eg. dpm/100 cm²), then the instrument should be configured for dpm and the appropriate factor should be placed in the Efficiency parameter.
ther choices are to have count mode units of R/h or Sv/h, in which case the COUNT mode result is an averaged exposure or dose rate. But if count mode units of R or Sv are chosen, the result is shown in accumulated exposure or accumulated dose over the chosen count time.
The following tables lists the possibilities:

Table 2.1: COUNT Mode Units and Result

In COUNT mode, operation depends on the current state of the Count Timer.
When the Count Timer is Ready:

• The display will show the Count Time.

• A short press of the UNITS button will switch between the Primary and Secondary Count Units. The newly selected Count Units will be displayed for approximately one
  second, and the display will then return to the Count Timer.

• A long press of the ON/OFF will initiate a countbut will not log the results upon completion.

• An extra-long press of the UNITS button will change the count time to the next available time.

• Pressing and holding the UNITS button will also change the count time to the next available time but will scroll through all possible count times at approximately onesecond intervals.

• If other operational modes are available, a short press of the MODE button will move to the next available operational mode.

• By default, a short press of the LOG button will initiate a count and log the displayed result upon completion, if datalogging is enabled.

When the Count Timer is Active:

• The display will show either Count Time (default), both Count Time and Counts, or just Counts, depending on Device Count Display Mode.
• If needed, a long press of the ON/OFF button will stop the count and reset the Count Timer(results will not be logged if previously requested).
• Click audio, if enabled, can be adjusted by a short press of the AUDIO button.
• If an alarm condition occurs, the ALARM display indicator will turn on, and the Alarm audio will sound as soon as the count is complete. (If the count unit is an averaged rate, it is possible for the ALARM icon to come on during the count, but if the averaged rate falls below the alarm threshold by the end of the count, no ALARM will be active.)
• If other operational modes are available, a short press of the MODE button will cancel the current Count Timer and move to the next available operational mode.
• By default, the LOG button is unused during a count.

When the Count Timer has Finished:

• The display will show either the accumulated total for c, d, R, and Sv, or the timed ratemeter average for cps, cpm, dpm, or the average exposure or average dose in R/h
  and Sv/h.

• If datalogging is enabled and logging the count results was previously requested, the results will be logged to the log buffer.

• A short press of the UNITS button will switch between the Primary and Secondary Count Units.

• a long press of the ON/OFF button will reset the Count Timer and initialize for a new count.

• If an alarm condition occurred during the Timed Count, a continuous audio tone will sound as the ALARM display indicator will already be on. To acknowledge and turn off the continuous tone alarm audio, a short press of the ON/OFF button is required.
  To clear the alarm condition and reset the Count Timer, a long press of the ON/OFF button is required.

• If other operational modes are available, a short press of the MODE button will move to the next available operational mode.

• By default, a short press of the LOG button will log the current display.

SETUP MODE

Only advanced users or administrators should consider changing any of the parameters in the following section. Incorrect settings could jeopardize the safety of users depending on this instrument.
4.1 Setup Overview
Your instrument has been shipped from Ludlum Measurements only after passing electronic checkout, a 24-hour burn-in process, and a careful calibration process. Calibration papers are supplied with each instrument shipped from Ludlum Measurements.
Recalibration should be accomplished after a predetermined calibration frequency (Ludlum Measurements, Inc. recommends no more than a one-year interval), or when the operation of the instrument is suspect or maintenance has been performed on the instrument. Recalibration is not normally required following instrument cleaning or battery replacement. While recalibration does not require any special tools or software to perform, Lumic software available through Ludlum Measurements, Inc. will greatly ease calibration, especially when second-order deadtime correction (extended calibration) is being utilized. As a result, the use of Lumic software is highly recommended.
Ludlum Measurements offers a full-service repair and calibration department. Not only do we repair and calibrate our own instruments, we also service most other manufacturers’ instruments. Calibration procedures are available upon request for customers who choose to calibrate their own instruments.
**Ludlum Measurements, Inc. recommends recalibration at intervals no greater than one year, assuming that regular operational checks are performed. Check the appropriate local, state, and federal regulations to determine required recalibration intervals.
4.2 Setup Parameters**

Table 4.1: Setup Parameters

4.3 Entering Setup Mode
To enter Setup Mode, power down the Model 3005 then turn the unit back ON. When the instrument has begun normal operation, three short presses of the MODE button will place the instrument into Setup mode.
This process is different if you are in Sigma Audio Mode, rather than in the “click” Audio Mode. While trying to enter Setup Mode with Sigma Mode enabled, once the screen begins the Sigma countdown, press the Mode button three times. Do not wait until the countdown is complete, which will prevent you from getting into the Setup Mode. There is no countdown for the “click” Audio Mode.
Entry to Setup Mode can be confirmed when the numeric portion of the display shows P-1, indicating the first setup page is selected. If you simply wish to view the parameters, select the desired Setup Page by a short press of the MODE button. A short press of the UNITS button will advance through the parameters available on the selected Setup Page. To return to normal operation, advance back to the Setup Page selection by pressing the UNITS button for at least a half second. Pressing the UNITS for at least a half second again will exit, or holding the UNITS button for approximately 5 seconds will exit from anywhere in the menu.
If the menu is not exited properly, any changes made will not be saved.
SETUP PROTECT: By default, the Model 3005 is shipped with DIP Switch 2 in the OFF (back) position and all available Model 3005 parameters may be modified in Setup mode. To protected the Model 3005 from changes in Setup mode, open the instrument, by removing the six screws on the bottom of the can, and slide DIP Switch 2 (the rightmost switch) to the ON (forward) position to activate Setup Protect Mode.
****The dipswitch has a plastic cover, which protects the switch during manufacturing. This plastic cover is left on the dipswitch after assembly and is not removed until the dipswitch is needed. If the plastic cover still remains on the dipswitch, please remove the cover before changing the switch settings.
There are four different options for protect mode, which can be set through the Lumic 2.0
Calibration Software. Locate the Parameter “Setup Prtct” in the Dev tab and select the desired option.

• Normal: All parameters are protected from change through the device menu. This is the default mode when the Setup Protect dipswitch is configured to the ON position.
• Bypass Alarms: All parameters except for Rate, Count, and Dose Alarms are protected from change through the device menu.
• Bypass Alarms Count: All parameters except for Rate Alarms, Count Alarms, Dose Alarms, and the User Defined Scaler Count Time are protected from change through the device menu.
• Bypass All: All parameters may be changed from the Setup Menu, similar to leaving the Setup Protect DIP Switch set to the OFF position.

With the DIP Switch 2 in the ON position, setup mode may be entered through the front panel, and any parameter which has not been bypassed may be viewed, but changes cannot be made. Only bypassed parameters may be changed.
DISPLAY BACKLIGHT ‘Continuous On’: The Model 3005 display backlight can be set to remain on continuously during operation. Follow the steps from SETUP PROTECT to access the DIP switch but change DIP Switch 1 for display backlight selection. Setting DIP Switch 1 to the ON (forward) position will configure the display backlight to remain on during operation. Set DIP Switch 1 to the OFF (back) position, and the display will be backlit only when light levels are low.
Setting the display backlight for continuous-on operation can result in reduced battery life. The backlight can be configured to always be off as well through the device menu or Lumic 2.0 Calibration Software.
4.4 Setup Mode Operation
Once the Model 3005 is in Setup mode, setup page selection will be displayed on the LCD and the Page number will be blinking indicating it as the selected item. The number of available parameters per Setup Page will be displayed using the graph where the number of segments indicates the number of parameters. Short press the MODE button to choose the Setup Page you are interested in. Once the desired Setup Page is shown, short press the UNIT button to cycle down to the first parameter of that Setup Page. Further short presses on the MODE button will cycle down through the parameters for that page. Extra-long-pressing the UNIT button will go back up to the Setup Page. Extra-long pressing again will exit the Setup Mode.

Figure 4.1: Setup Page Selection Display (showing page 4-CAL)

To exit more quickly, press and hold the UNIT button. No matter what parameter is shown, it will walk the user through all previous Setup Menu levels until the instrument returns to normal operation.
When you get to a parameter that you want to change, use the MODE button to make the change. If numbers are displayed on the parameter, the MODE button will increment the numbers. Otherwise, the MODE button will cycle through the available settings. When you have adjusted the parameter setting to your desired number or setting, extra-long press the UNIT button. This will save the change and send you back up one screen to the page parameters. If more than one parmeter can be changed on the page, short press the ON/OFF button to advance through the available parameters then used the MODE to change the parameter.
For example: Rate Mode, Unit 1, Alarm 1 Value to 150 mR/h.
Enter the Setup Menu.

• Use the MODE button to advance to P-2.
• Press the UNIT button to enter the menu.
• Press the UNIT button to get to the third of the seven menu items. This is the parameter setting for the “Unit 1 RATE/MAX Mode Alarm 1.”
• Press the ON/OFF button to advance to the tens digit.
• Press the MODE button to increment the value to 5.
• Press the ON/OFF button to advance to the hundreds digit.
• Press the MODE button to increment the value to 1.
• Press the ON/OFF button to advance to the decimal point.
• Press the MODE button to until no decimal is displayed.

Calibration Constant Mantissa** – A short press of ON/OFF to select the value to adjust, and MODE to adjust the value. Value is used with Calibration Constant Exponent to express counts per R. Available values are:

• Ones Place (0-9)
• Tens Place (0-9)
• Hundreds Place (0-9)

Calibration Constant Exponent – A short press of ON/OFF to select the value to adjust, and MODE to adjust the value. Value is used with Calibration Constant Mantissa to express counts per R. Available values are:

• Ones Place (0-9)
• Tens Place (0-9)

Dead Time Correction 1 – A short press of ON/OFF to select the value to adjust, and MODE to adjust the value. Value is in microseconds. Value should be set to zero when checking instrument with a pulser or function generator; otherwise, higher count rates will result in non-linearities. Available values are:

• Ones Place (0-9)
• Tens Place (0-9)
• Hundreds Place (0-9)

Dead Time Correction 2 Mantissa – A short press of ON/OFF to select the value to adjust, and MODE to adjust the value. Available values are:

• Ones Place (0-9)
• Tens Place (0-9)
• Hundreds Place (0-9)

Dead Time Correction 2 Exponent – A short press of ON/OFF to select the value to adjust, and MODE to adjust the value. Available values are:

• Number of Decimal Places (0 or 1)

Normally the efficiency is used on a per detector basis or 4pi basis, i.e. the efficiency of the detector is calculated by dividing the count rate received from a source by the total disintegration rate of the source. When either dpm or Bq units are chosen, the use of the 4pi efficiency allows the display of the source size or activity on the Model 3005 display.
But if the user desires to have the Model 3005 show results in terms of dpm/100 cm2, the user could manipulate the efficiency to produce this result by multiplying the efficiency times the ratio of the detector area to 100 cm2. For example, using a detector with an area of 15 cm2, if we start with 10% efficiency to measure in dpm, then the parameter could be changed to 1.5% to measure in dpm/100 cm2.
Or likewise for Bq/cm2, efficiency could be calculated as: efficiency = count rate/disintegration rate*detector area (in cm2). For example, with the same detector as above with an area of 15 cm2, and starting with an efficiency value of 15%, then the parameter could be changed to 225% to measure in Bq/cm2.

DATALOGGING

The datalogging feature of the Model 3005, accessible through the use of the optional Lumic Datalogger software kit, allows the user to log radiation readings with the use of a handlemounted LOG button. Data can be logged in any of the Model 3005’s operational modes (RATE, MAX, and COUNT). Up to 1000 data points can be taken and stored internally. Depending on the chosen Datalogging Mode, the user can quickly save logged data using a single Location ID, or select from up to 250 stored Location IDs. A Real Time Clock (RTC) is utilized to time and date stamp each datalog entry.
The saved log data and stored location IDs can be viewed, downloaded, and erased using the LMI Lumic Datalogger software kit, which includes a USB cable. Editing of datalogging parameters and RTC via setup mode on the instrument is disabled.
Setup of the datalogging parameters is also done through the LMI Lumic Datalogger software.
The advanced user or administrator can set:

• Datalogging Mode
• Real Time Clock (RTC) Values
• Location IDs

5.1 Datalogging Operation – Mode 1
Datalogging Mode 1 will store the logged data using only the first Location ID in the Location ID table.

• When the LOG button is pressed, the current radiation reading and other log data is saved along with the first Location ID in the format specified in the Specifications at the end of this section.
• In COUNT Mode:
  • During a count, the LOG button is disabled until completion of a Scaler count.
  • For a continuous Scaler count (Scaler time is 0), the LOG button is enabled at all times.
• For approximately 2 seconds, the LCD will display the Datalog Table index for the newly saved log data.

Figure 5.1: Displaying Datalog Table Index of 12

• After displaying the Datalog Table index, the instrument will return to the previous mode of operation.
• The Datalog Table is linear; once the table is full, no further writes will be allowed until the Datalog Table is erased.
• If an attempt is made to write to a full Datalog Table, several 1/4 second audio alerts will sound and the maximum Datalog Table index (1.00 k) will be displayed for about 2 seconds. The instrument will then return to the previous mode of operation.

5.2 Datalogging Operation – Mode 2
Datalogging Mode 2 will allow the user to choose the Location ID (by Location ID Table index) to store with the logged data.

• When the LOG button is pressed, the current radiation readings and other log data are temporarily stored.
• In COUNT Mode:
  • By default, Mode 2 is disabled during a count; instead, the datalogging feature functions as it would in Mode 1.
• The LCD display will show a possible Location ID Table index for the user. The index will be auto-incremented from the previously used index.

Figure 5.2: Displaying Datalog Location ID Table Index of 36

• The number will be blinking, indicating a changeable value. The user may then enter the preferred Location ID Table index by a short press of the MODE (to increment the value) as in Setup mode.
• Once the user has the preferred Location ID Table index entered, a short press of the LOG button will save the log data.
• After displaying the Datalog Table index, the instrument will return to the previous mode of operation.
• The Datalog Table is linear; once the table is full, several 1/4 second audio alerts will sound and the maximum Datalog Table index (1.00 k) will be displayed for about 2
  seconds, and no further writes will be allowed until the Datalog Table is erased.

5.3 Datalogging Operation – Mode 3
Datalogging Mode 3 will automatically record data log records using the current location saved in Location Mode 3 with the user settable auto log interval, Mode 3 Timer, settable to record every 1 to 1800 seconds.

• When the Device is turned on and in RATE or MAX mode, the current radiation reading and other log data is recorded at the set interval.
• In SCALER Mode:
  • Auto log will be paused and will only log at the completion of each count.
  • For a continuous Scaler count (Scaler time is 0), logs will be recorded at auto log interval.
• No visual indication will occur.
• The Datalog Table is linear; once the table is full, a 1/4 second audio alert will sound at the autolog interval, and no further writes will be allowed until the Datalog Table is erased.

When connecting to Lumic 2 software or Lumic Data Logging software while the instrument is logging in Mode 3, the instrument may disable data logging to prevent conflicts from occurring while both reading and writing to the data log buffer. While this will be immediately reported when reading from the instrument, this will not be immediately noticed when pulling the data log records from the instrument. Always read from the instrument and check the status of ’Is Logging Enabled’ using the Data Logging Software before exiting the softwareto ensure your instrument is functioning properly.
**A short press of the LOG button will start a count and automatically log the result. An extra-long press of the UNIT button during the count will toggle the display between the timer and reading.

SOFTWARE

6.1 Connecting to Lumic 2.0 Calibration/Configuration Software
The Lumic 2.0 Calibration/Configuration software is sent with a standard two-meter cable. (A five-meter cable can be provided if requested. However, any cable longer than two meters may have issues with some USB hubs and computers, typically laptops.)
To connect an instrument to the computer, please connect one end of the USB cable to the instrument first, and then the other end to the computer. Do not connect both ends to the computer.
Please allow Windows® a moment to install the proper HID drivers for the instrument before trying to use any software.
We recommend that you plug the USB cable into the back of your PC that connects to your motherboard instead of a USB hub.
Some parameters may only be edited in software, such as the backlight thresholds, COUNT Display Mode, COUNT Audio Mode, and Setup prtct.
Follow the Lumic 2.0 Calibration/Configuration software manual.

ADVANCED FEATURES

7.1 Dead Time Correction
All pulse counting detectors have a “dead time” in which the detector is unable to register another event. In relatively low fields this is not an issue. However, as the field strength approaches the high end of the detector’s range, dead time causes the pulse rate to become non-linear with respect to the real radiation field. Dead time correction is used to linearize the measurements, allowing a wider linear response range for a given detector.
This instrument uses a second order dead time correction using the equation

Where DTC1 and DTC2 are the dead time correction coefficients, r atem is the measured count rate, and r atec is the corrected rate.
Dead time correction coefficients are configured through the device setup menu or through Lumic Calibration software. Lumic Calibration software also includes a wizard that will automate finding and setting the correct coefficients.
DTC1 is represented in microseconds (&s) on the device setup menu and in the software. The equation must be calculated in terms of seconds (s) and must be scaled appropriately. DTC2 has more complex units and are not shown. However, the representation of the coefficient on the setup menu and in software do not require scaling. **Setting the DTC2 to zero will disable the second order correction, while setting DTC1 to zero will disable both, regardless of the value of DTC2.
7.2 Units**
Depending on the chosen display units, different features will affect the value of the reading.
The following table lists the features that apply to each of the display units.

Table 7.1: Features That Affect Units in All Modes

7.3 R to Sv Conversion
The R to Sv conversion is a setting available in Lumic Calibration software. It defines the conversion factor between R and Sv. Since the calibration constant is directly tied to R (counts per R), calibrating Sv requires a correct setting of both calibration constant and R to Sv conversion.
Example: An R to Sv conversion factor of 0.0106 will cause a reading of 10.6 mSv/h while in a 1 R/h field.
7.4 Software Calibration Tools
Lumic Calibration software includes wizards that will assist in calibrating and plateauing detectors. After configuring the wizard for a specific detector, the wizard will automate much of the data collection and calculation required for calibration.
7.5 Instrument Calibration
This instrument provides the ability to digitally enter a voltage for both high voltage and threshold. As such, the instrument itself needs to be calibrated. This happens at the factory when the instrument is built and should not require re-calibration. However, if calibration is required (due to board rework, etc.) the calibration settings are available in Lumic Calibration software.
7.6 Other Device Data
The following parameters on the instrument allow recording import device information within the device:
Firmware Version: This is a read-only presentation of the firmware version. With a firmware version of F.x.y.zzzz, the F.x.y will show up on the device screen during the power-on sequence and signifies the released version.
Device – Model Name: This should match the model name on the front face of the instrument.
Device – Serial Number: This should match the serial number of the instrument.
Detector – Model: This can store the model of the detectors the instrument was calibrated for.
Detector – Serial Number: This can store the serial number of the detectors the instrument was calibrated for.
7.7 Battery Life
The instrument leaves the shop with adjustments to meet most consumer demands; however, advanced users may use the Lumic software to adjust the LED and backlight brightness to maximize battery life. By changing the backlight mode of operation and adjusting the brightness settings for the backlight and LED to meet user needs, it is possible to reduce battery current consumption by as much as 50%.
7.8 Real-time Streaming
Lumic Calibration 2.0 software and this instrument have the ability to stream data from the instrument to a computer. The data can be viewed live inside software or can be recorded in a file.
Multiple user-selected parameters can be streamed simultaneously including:

• Remote display of the screen
• All unit values
• Device status
• Live HV current measurement

7.9 Button Mapping
By default, the LOG button’s primary purpose is to take a log of the current display or initiate a count, in COUNT mode, and log the result upon completion assuming datalogging is enabled. Lumic Calibration 2.0 software allows the LOG button to be configured (this is referred to as button mapping) to perform a number of features. In some cases, the available features are only useful for a particular function. As a result, the LOG button can be mapped for RATE/MAX modes and COUNT mode separately.
Using the Lumic Calibration 2.0 software, the user can select among the following features, which can be mapped to the short press, long press, and extra-long press of the LOG button.

• Do Nothing – This button press has no effect. This is the default configuration for a long press and an extra-long press of the LOG button.
• Take Log – Log the current display or initiate a count in COUNT mode and log the results upon completion (assuming datalogging is enabled). This is the default configuration for a short press of the LOG button.
• Change Units – Changes to the next available unit. This is similar to a short press of the UNITS button.
• Toggle Click Audio – Changes the audio level. This is similar to a short press of the AUDIO button.
• Change Modes – Changes to the next available mode of operation. This is similar to a short press of the MODE button.
• Toggle Count Display (COUNT mode only) – In COUNT mode, if the count is active, this will switch between the count timer and the count display. This is similar to the extralong press of the UNITS button in COUNT mode. This has no effect in RATE/MAX modes and should not be used in RATE/MAX button mapping.
• Reset Rate (RATE/MAX mode only) – This will reset the currently displayed rate. This has no effect in COUNT mode.
• Advance Count Mode (COUNT mode only) – In COUNT mode, if the count is ready then the button will initiate a count without logging the results upon completion. If the count is in process, the count will be stopped and the count timer will be reset. If the count has concluded, the count timer will be reset.
• Do Nothing – This button press has no effect. A repeat of the aforementioned ’Do Nothing’, this feature supports backwards compatibility with previous versions of firmware previously released with button mapping capability.

7.10 CPS Offset
Using the Lumic Calibration 2.0 software, the user can enter a CPS Offset for a given channel. The CPS Offset is counts per second, which are subtracted from the channel reading’s base counts before any dead time correction or unit conversion is applied. This is a useful method by which to perform background subtraction in a controlled environment.
****The instrument does not calculate the CPS Offset for the user. The CPS Offset is a fixed value, which must be configured while the instrument is connected to the Lumic Calibration 2.0 software and which is stored in the instrument and reused each time the instrument is powered on.
By default, CPS Offset is 0 and no count subtraction is performed.
