IMPORTANT! BUMP TEST THE MONITOR BEFORE EACH DAY’S USE
Prior to each day’s use, every gas detection monitor should be bump tested to confirm the response of all sensors and activation of all alarms by exposing the monitor to a concentration of target gas that exceeds the low alarm set point. A  bump test is also recommended if the monitor has been subjected to physical impact, liquid immersion, an Over Limit alarm event, or custody changes, or anytime the monitor’s performance is in doubt.
To ensure greatest accuracy and safety, only bump test and calibrate in a fresh air environment.
The monitor should be calibrated every time it does not pass a bump test, but no less frequently than every six months, depending on use and exposure to gas and contamination, and its operational mode.

• Calibration intervals and bump test procedures may vary due to national legislation.
• Honeywell recommends using calibration gas cylinders containing the gas that is appropriate to the sensor you are using, and in the correct concentration.

Keys & Interface
The MicroRAE has two keys:

In addition to their labeled functions, the keys labeled [MODE] and [Y/+] act as “soft keys” that control different parameters and make different selections within the instrument’s menus. From menu to menu, each key controls a different parameter or makes a different selection.
In addition to the functions described above, either key can be used to manually activate display backlighting. Press a key when the backlighting is off to turn it on.
Screen display for various numbers of active sensors
The MicroRAE can accommodate from one to four sensors. When one or more sensors is either not installed or turned off, the display only shows the installed, active sensors:

Menus
The reading menus are easy to step through by pressing the [MODE] and [Y/+] key.

* If the MicroRAE is Wi-Fi equipped: Wi-Fi-equipped instruments can receive up to five messages. If a message has been received by the MicroRAE, the number of messages is displayed (1 MSG, etc.). The display shows the message  sequentially, cycling through the message each half-second. The Message number, “page” of the message (it automatically breaks a message across screens), and received time and date are shown. Up to five messages can be received by  the MicroRAE. Pressing [MODE] steps through the messages. When “Exit” is shown, press [Y/+] to return to the Main Display.
Note: In most cases, if no buttons are pressed at any of the menu steps for 60 seconds, the instrument reverts to the main display.
Glance Mode
If you want to check your instrument’s configuration and it is turned off, you do not have to turn it on. Press and hold [Y/+] until the screen illuminates and shows the configuration. This tells you the installed sensors:

Press [Y/+] to advance through screens that tell you if the radio is on, BLE is on, GPS is on, WiFi is on, etc. These change, depending on the instrument’s configuration.
To exit, press [MODE], and the display shuts off.
Note: If you do not press a button for 60 seconds, it turns off automatically.
Panic alarm
Press and hold [Y/+] at any time to trigger the Panic Alarm. The display shows “PANIC ALARM” and sends a message to Safety Suite software. (Note: Use Safety Suite software to define information and its prioritization for viewing.)

Press [Y/+] to clear the alarm. The alarm stops and the display returns to the main reading screen.
Confidence LED
You can use Safety Suite Device Configurator (SSDC) to program the MicroRAE to continually provide an LED blink every 3 seconds so that you can tell without looking closely that the instrument is working.
Mesh wireless control and submenus
When you step through the main menu, as shown in the Menus diagram, there are four screens for wireless communication, containing information on wireless settings and status. If Roaming is not turned on, then you must set a PAN ID in order to communicate with a Mesh Network.
Note: These are only present if the MicroRAE is equipped with a Mesh Network wireless module.

BATTERY CHARGING

Always fully charge the battery before using the MicroRAE. Its Li-ion battery is charged by placing the MicroRAE in its Travel Charger (P/N: M03-3005-000) or Charging Cradle. Contacts on the bottom of the instrument meet the Travel Charger’s or Charging Cradle’s contact pins, transferring power.
Note: Before attaching the MicroRAE to a charger, visually inspect the contacts to make sure they are clean. If they are not, wipe them with a soft, dry cloth. Do not use solvents or cleaners.
WARNING
To reduce the risk of ignition of hazardous atmospheres, recharge, remove or replace the battery only in an area known to be non-hazardous!

Align the Travel Charger with the middle of the MicroRAE, squeeze the latches on both sides of the Travel charger, and press it until it is firmly attached to the MicroRAE. Then release the latches. Make sure you press the latches close to  the instrument instead of at their ends, or they could be broken and/or charging may not occur.
Next, put the plug from the power supply (P/N: 500-0036-102) into the jack on the side of the Travel Charger.

Plug the other end of the charger into a power source (AC outlet or mobile power port in a vehicle, depending on the model). When power is applied and the Micro Rae’s battery is charging, the LED glows red. The LED glows green when  the battery is fully charged.
Note: For mobile charging, only use Automotive Charging Adapter (P/N 003-3004-000) from Honeywell.
To remove the MicroRAE from the Travel Charger, squeeze the latches on the sides of the Travel Charger and pull it away from the instrument. Always press near the top of the latches, not the ends. Pressing at the ends could lead to broken latches and/or cause the instrument to not be charged.

Charger station (Multi-Charger)
A Multi Charger (P/N: M03-0300-000) is available for charging up to five MicroRAE instruments at one time.
Note: It uses a different AC adapter (P/N: 500-0156-000) than the travel charger.

Insert the plug from the power supply into the jack on the side of the Multi Charger: Plug the other end of the charger into a power source.

Charging with the Multi Charger
Press the MicroRAE into any of the Multi Charger’s cradles. It should be held firmly in place. If the power is connected to the Multi Charger, the LED indicator on the cradle should glow.

Battery states
The battery icon on the display shows how much charge is in the battery and alerts you to any charging problems.

When the battery’s charge falls below a preset voltage, the instrument warns you by beeping once and flashing once every minute. The instrument automatically powers down within 10 minutes, after which you will have to recharge the  battery.
A “low” battery should be recharged as soon as possible. For improved battery life, avoid allowing a battery to discharge below 10% capacity.

EXTERNAL FILTER

The External Filter (M03-3009-000) is designed to prevent debris from entering the MicroRAE in dirty or dusty environments. Align the filter over the sensor openings and tighten the Philips screw to secure it in place. Replace the filter when it appears dirty.

OPERATION

Turning the MicroRAE on and off
Turning the MicroRAE on
With the instrument turned off, press and hold the [MODE] key until the audible alarm stops, and then release.
When starting up, the MicroRAE turns the backlight on and off, beeps once, blinks once, and vibrates once. A RAE Systems logo should appear first. During a normal startup, this is followed by a progression of screens that tell you the Micro Rae’s current settings.
Then the Micro Rae’s main reading screen appears. It takes 45 seconds for some sensors to show a reading, so if any have not warmed up by the time the main screen is shown, you will see “- -” instead of a numerical value until the sensor  provides data (if you turn a sensor off and on again, it also shows “- -” for up to 45 seconds). Then it displays instantaneous readings similar to the following screen (depending on the sensors installed) and is ready for use.
Note: If the battery is completely empty, the MicroRAE shuts off. You should charge the before turning it on again.
CAUTION
If a major error that prevents the MicroRAE from functioning is found during startup, the message “Contact Service” is shown on the display. The instrument should be shut off and serviced.
Turning the MicroRAE off
Press and hold [MODE]. A 5-second countdown to shutoff begins. You must hold your finger on the key for the entire shutoff process until the MicroRAE is powered off.
CAUTION

• Use a unique password. Do not reuse passwords used in other systems or for other purposes. Avoid using examples found on the Internet, in literature etc.
• Use a long sequence of random characters (at least eight characters).
• Use a mix of different types of characters, such as uppercase and lowercase letters, numbers, punctuation marks, etc.
• To make the password easier to remember, begin with a sentence, verse, book title, line from a song etc. Omit or change certain letters. For example, use only the first few letters from each word, replace some letters with numbers or punctuation marks (for example replace all letters “a” with dots “.”), etc.
• Avoid using easily guessable phrases, like names, words found in dictionaries, years, birthdays, phone numbers, etc.
• Avoid using the most popular passwords, such as “123456”, “qwerty”, “password” etc. Also avoid using them even in modified formats, such as “Qwerty” or “Pa55vv0rD”.
• Protect the password while archived. Use trusted and properly configured password vaults for this purpose.

SSID
The SSID (Service Set Identifier) is a case-sensitive unique identifier attached to the header of packets sent over a wireless local-area network. Each wireless network in your range will have its own SSID. Consult with your IT department  for the SSID.
Server IP
This is the destination IP address for the instrument to communicate with a computer running Safety Suite Device Configurator (SSDC).
Server port
The port number is distinct from any physical port on a computer such as a COM port or an I/O port address. It is a 16-bit address that exists only for the purpose of passing certain types of information to the correct location above the  transport layer of the protocol stack.

ALARMS OVERVIEW

The MicroRAE provides an unmistakable five-way alarm notification system that combines local alarms on the device with real-time remote wireless alarm notification to enhance worker. Local alarms include audible buzzer alarm, visible alarm via bright LED lights, vibration alarm, and an alarm notification on the display. These can be programmed or selectively turned on or off.
Testing alarm indicators
Under normal-operation mode and non-alarm conditions, the buzzer, vibration alarm, LED, and backlight can be tested at any time by pressing [Y/+] once.
WARNING
If any alarm does not respond, check MicroRAE’s alarm settings to make sure all alarms are enabled (selected setting under Programming/Alarms/Alarm Settings should be “All Enabled”). If any alarms are enabled but not functional, the  instrument should not be used.
Comfort beep
A Comfort Beep is a single beep of the audible alarm at 60-second intervals that provides a reminder that the MicroRAE that it is functioning. It can be turned on or off.
Man Down alarm
The Man Down Alarm is a critical and potentially lifesaving safety feature of every MicroRAE.
The Man Down Alarm is based on the premise that if the instrument is motionless when it is not supposed to be, something wrong may be happening to its user. If that is the case, the MicroRAE not only goes into alarm locally on the  instrument, but also remotely, over a wireless network, to notify people in the vicinity, as well as remote safety officers at a command center, that a person is down, so that help can be dispatched quickly.
Note: Remote notification requires wireless connection to a network.
Whenever the Man Down feature is on, the main screen displays a Man Down icon along the top to indicate it is active:
IMPORTANT!
When gas alarm conditions exist at the same time as the Man Down alarm is activated, the prelim stage is skipped, and the instrument goes straight into Super Alarm (gas and Man Down) with four beeps/flashes per second.
When the Man Down feature is on and there is no gas alarm, the MicroRAE senses that it is motionless for the amount of time set in the “Motionless Time” parameter via Safety Suite Device Configurator (SSDC). If the instrument is not  moved during that time, then a pre-alarm is activated to alert the user, and shows the “OK?” screen. Pressing [Y/+] clears the alarm and returns the MicroRAE to its normal operation. Pressing [MODE] sets it into Man Down Alarm (and if wireless connectivity is enabled, a Man Down message is sent in real time to remote observers). If neither key is pressed, then after the countdown, it goes into Man Down Alarm (again sending a message to remote observers if  wirelessly enabled).
Settings for Man Down are available in Safety Suite Device Configurator (SSDC) for:

• Off/On
• Man-down alarm sensitivity (set to low, medium, high, or custom percentage)
• Fallow Sensitivity (set to low, medium, or high to compensate for ambient vibration or motion) Falldown warning after (time the instrument is motionless before initiating a pre-alarm, in seconds)
• Falldown alarm after (time after falling down is sensed, in seconds); Whenever the acceleration speed is greater than the Falldown Sensitivity, the Man Down feature is invoked.
• Warning after (countdown, in seconds, from pre-alarm to Man Down alarm)

When the Man Down alarm is activated, the buzzer sounds and LEDs flash continuously, and a countdown begins.

• If the MicroRAE’s user presses [Y/+] for “Yes” in response to the “OK?” question on the screen before the countdown reaches zero, the Man Down alarm stops and the main reading screen is displayed.
• If the person does not press [Y/+] for “Yes” in response to the “OK?” question on the screen before the countdown reaches zero, the Man Down alarm is sounded and LEDs flash continuously.
• If the person presses [MODE] during the countdown, answering the “OK?” question by pressing [MODE] for “No,” the Man Down alarm starts.

If wireless connectivity is enabled, and the MicroRAE is connected to a network, a Man Down message is also sent to remote observers.

IMPORTANT!
When using the Travel Charger or Truck Mount to charge a MicroRAE, the Man Down alarm is automatically disabled so that the instrument does not go into Man Down alarm because of inactivity. This requires no changes to the instrument’s settings.
Please note that Travel Chargers with a serial number lower than M0320001U5 and Truck Mounts with serial numbers lower than M035000170 do not support this feature. It is also recommended that older MicroRAE instruments have  their firmware upgraded to version 1.10 or higher.
Parameters settings and sequence of events
When a fall is sensed, as determined by the Motion Sensitivity and Falldown Sensitivity settings, the Falldown Window starts. If motion resumes, then the instrument resets itself and is ready for the next fall or motionless period.
Parameters configured by Safety Suite Device Configurator (SSDC)

Medium (37%),
High (63%), Custom
5| Falldown sensitivity| Medium| Low (33%)
Medium (67%),
High (100%),
Custom

If acceleration is sensed, and motion does not resume, then the Warning Time starts. During this period, the instrument waits for motion. If no motion occurs by the end of the Warning Time, the Window period is entered. During that  time, the display shows the “Are You OK?” message. The buzzer sounds and LEDs flash continuously, and a countdown begins.

• If the MicroRAE’s user presses [Y/+] for “Yes” in response to the “Are You OK?” question on the screen before the countdown reaches zero, the Man Down alarm stops and the main reading screen is displayed.
• If the person does not press [Y/+] for “Yes” in response to the “Are You OK?” question on the screen before the countdown reaches zero, the Man Down alarm is sounded and LEDs flash continuously.
• If the person presses [MODE] for “No” during the countdown, the Man Down alarm starts.

If wireless connectivity is enabled, and the MicroRAE is connected to a network, a Man Down message is also sent to remote observers.
Turn Man Down on or off
Turn on or off the Man Down feature by clicking on the check box using Safety Suite Device Configurator (SSDC)

Set the sensitivity
Individual sensitivity settings for Motion (acceleration) and Falldown allow for customization to individuals or activities. Default values are set at the factory, but it can be helpful to try other settings in order to customize an instrument’s response.

Set the times
Once a trigger occurs, there is a time before a warning is displayed and when the Man Down alarm is initiated.

Upload settings to the MicroRAE
When any changes to Man Down (or any other) settings are made in Safety Suite Device Configurator (SSDC), you must upload them to the instrument in order for them to be used. Click the “Save” button.

For further information
Consult the Safety Suite Device Configurator (SSDC) User’s Manual for more details on parameters and settings.
Alarm signals
During each measurement period, the gas concentration is compared with the programmed alarm limits for Low, High, TWA and STEL alarm. If the concentration exceeds any of the preset limits, the alarms are activated immediately to  warn both the MicroRAE user and a remote safety officer (if wireless is enabled) of the alarm condition.
In addition, the MicroRAE alarms if the battery voltage is low.
When the low battery alarm occurs, there may be approximately 10 minutes of operating time remaining. In this case, it is recommended that you promptly charge the battery in a nonhazardous location.
Note: The default setting for the alarms is “unlatched.” To change this to latched mode, you must use Safety Suite Device Configurator (SSDC) software

  Manual alarms test
  Under Normal Operation Mode and non-alarm conditions, the buzzer (audible alarm), vibration, visible alarms, and backlight can all be tested anytime by pressing [Y/+]. If any alarm does not respond, connect the MicroRAE to a PC running Safety Suite Device Configurator (SSDC) and check the alarm settings to make sure all alarms are enabled. If any alarms are enabled but not functional, the instrument should not be used. Contact Honeywell Technical Support.

CALIBRATION AND TESTING

Bump testing and calibration
Prior to each day’s use, every gas detection monitor should be bump tested to confirm the response of all sensors and activation of all alarms by exposing the monitor to a concentration of target gas that exceeds the low alarm set point. A  bump test is also recommended if the monitor has been subjected to physical impact, liquid immersion, an Over Limit alarm event, or custody changes, or anytime the monitor’s performance is in doubt.
To ensure greatest accuracy and safety, only bump test and calibrate in a fresh air environment.
The monitor should be calibrated every time it does not pass a bump test, but no less frequently than every six months, depending on use and exposure to gas and contamination, and its operational mode.

• Calibration intervals and bump test procedures may vary due to national legislation.
• Honeywell recommends using calibration gas cylinders containing the gas that is appropriate to the sensor you are using, and in the correct concentration.

A bump test can be performed either manually or using the AutoRAE 2 Automatic Test and Calibration System. When a bump test is done manually, the instrument makes a pass/fail decision based on sensor performance, but the user  still has the responsibility to make sure all the alarms are enabled and functional.
Note: Bump testing and calibration can be performed using an AutoRAE 2 Automatic Test & Calibration System. An AutoRAE 2 bump test takes care of both the sensor and alarm tests.
Consult the AutoRAE 2 User’s guide for details.
Bump (functional) testing (single bump or multi bump)
The same gas is used for a bump test as for calibration. A constant-flow regulator producing 0.5 liters per minute (1 liter per minute for HCN sensors) should be used, and the calibration adapter must be installed. The instrument must be  connected to a cylinder of calibration gas with supplied tubing.

1. Turn on your MicroRAE by pressing and holding the [MODE] key, and allow the instrument to boot up fully until the main measurement screen with sensor names and readings is shown.
   Important! Make sure all of the instrument’s sensors have warmed up before performing a bump test. The instrument will take the time to warm up the sensors prior to enabling access to bump test menus. You can tell a sensor has warmed up if you see a reading next to it name on the display. If it has not warmed up, you see three dashes (“–”) next to it.

2. Install the calibration adapter on the MicroRAE by setting it on over the sensors and turning the knob until it is snug against the surface of the instrument.

3. Turn on the gas to initiate flow.

4. Connect the calibration adapter to the calibration gas.

5.  Press Start ([Y/+] key) to start the bump test, or press [MODE] to quit. While the bump test is being performed, the readings for each sensor are shown. Once the bump test completes, pass/fail test results and readings are shown  for each sensor.
   Important! If one or more sensors fails a bump test, be sure to calibrate those sensors.

6. The bump test is now complete. Press [MODE] to exit to the next bump or calibration type in the Calibration menu. (Press [MODE] several times until you see “Exit,” and then press [Y/+] to continue through other menu options.
   If all the alarms and all sensors have passed and no sensor is due for a calibration, the instrument is now ready for use.

Zero calibration
This operation sets the zero point of the sensor calibration curve for clean air. It should be performed before other calibrations.
Note: If you use a zero air cylinder, you must use the MicroRAE Calibration Adapter. Using a calibration adapter is not necessary for calibration in fresh air. This procedure determines zero points of most sensors. The MicroRAE should  be zero calibrated in clean air with 20.9% oxygen or with a cylinder of clean zero air.
At the Calibration menu, select “Fresh Air” by pressing [Y/+] once to enter fresh air calibration.
After a timer countdown, the zero calibration is done. The LCD displays the sensor names and tells you whether each calibration passed or failed, followed by the sensor readings.
Note: You can abort the calibration at any time during the countdown by pressing [MODE].
Single-sensor zero calibration
Select the sensor and then start the calibration by pressing [Y/+]. You can abort the procedure anytime by pressing [MODE].
Span calibration
This procedure determines the second point of the sensor calibration curve for the sensor.
Note: When a manual calibration is performed, the readings shown are in the equivalent units of the calibration gas, and not the measurement gas. When performing a Span calibration, the Calibration Adapter must be used for supplying calibration gas to all sensors at one time:

1. Align the Calibration Adapter’s main body with the indented area around the MicroRAE’s gas inlets.
2. Turn the knob clockwise to secure the Calibration Adapter to the instrument.
3. Connect the hose to the Calibration Adapter and to its gas source.
4. Make sure the Calibration Adapter is securely attached before starting the flow of calibration gas. (The Calibration Adapter has small grooves on its underside to allow gas to escape after passing over the sensors.)

Multi-sensor span calibration
This lets you perform a span calibration on multiple sensors simultaneously. It requires using the appropriate span gas and that the concentration labeled on the gas cylinder matches the concentration programmed in the MicroRAE.

1. Start the flow of calibration gas.
2. Attach the calibration adapter and gas to the MicroRAE.
3. Press [Y/+] to begin calibration. A countdown screen is shown. You can abort the calibration at any time during the countdown by pressing [MODE].

If the calibration reaches its conclusion, it shows the sensor names and tells you whether the calibration passed or failed, followed by the sensor readings.
Single-sensor span calibration
To perform span calibration of an individual sensor, follow these steps:

1. At the Calibration Menu, select “Single Sensor Span.”
2. Select a sensor from the list.
3. Start the flow of calibration gas.
4. Connect the calibration adapter and connect it to a source of calibration gas.
5. Verify that the displayed calibration value meets the concentration label on the gas cylinder.
6. Press [Y/+] to start calibrating. You can abort the calibration at any time during the countdown by pressing [MODE].

After a timer countdown, the span calibration is done. The LCD will display whether the calibration was successful and the reading for that calibration gas.
Note: If the sensor calibration fails, try again. If calibration fails again, turn off the power and then replace the sensor.
WARNING
Do not replace sensors in hazardous locations.

1. Turn off the instrument.

2. Remove the four screws in the back of the instrument.

3. Turn the instrument over.

4. Lift off the front cover from the back of the instrument. CAUTION
   In some MicroRAE instruments a wire connects the buzzer in the top to the circuit board in the bottom. Do not damage or remove it.

5. Carefully lift out each sensor you wish to inspect or replace.
   Note: Oxygen and toxics sensors are labeled on their sides. The sockets are also labeled.The LEL sensor is square and has four pins that insert into four plated holes in the PC board. When removing or installing an LEL sensor, lift it straight out and be careful not to bend the pins.

Replacing sensors

1. Install the replacement sensor. Make sure the electrical contact pins are aligned with the holes in the PC board and that the sensor is seated firmly.
2. Remove the plastic film from the top of the sensor.
3. Replace the cover and tighten the four screws.

WARNING
It is extremely important that sensors are installed in the correct orientation.
When installing a new sensor, the plastic film should be on top of the sensor. Once the sensor is installed, remove the plastic film.
IMPORTANT!
Always perform a full calibration after replacing sensors.
Replacing the LEL filter
If the LEL sensor appears dirty, it should be replaced with a new one (H2S filter P/N: 014-3603005, package of 5; or H2S & Si filter P/N: 014-3604-005, package of 5).

1. Remove the LEL filter from the gasket and dispose of it.
2. Replace the LEL sensor in its place in the gasket.

Replacing the waterproof membrane filter
The waterproof membrane filter (PN: M03-2007-000) is located inside the top of the case and prevents water and dirt from entering the instrument. If the filter appears dirty or if the instrument is having difficulty drawing in a sample,  check the waterproof membrane filter for contamination, and if necessary, replace it.

1. Make sure the MicroRAE is turned off.

2. Remove the four screws on the back to open the MicroRAE.

3. Place the top housing face-down on a flat surface.
   CAUTION
   In some MicroRAE instruments a wire connects the buzzer in the top to the circuit board in the bottom. Do not damage or remove it.

4. Remove the rubber seal and set it aside. It has a filter for the LEL sensor (blue rectangle).
   Note: Because the instrument is open, this is a good time to replace the LEL filter (See “Replacing the LEL filter” on the previous page for more information.)

5. Grip the currently installed waterproof membrane filter and pull it up. You may have to use a tweezers to get a firm grip. (If it leaves residue, blow it out with a can of compressed air.)  Discard the used waterproof membrane filter.

6. Set a new waterproof membrane filter on a flat surface. Peel off and discard one side’s paper covering that protects the adhesive.

7. With the paper removed from one side of the waterproof membrane filter, turn it around so that the side with paper on it is facing you. The adhesive side is now exposed, so do not set it down or allow it to contact other objects.

8. Carefully set the new waterproof membrane filter (PN: M03-2007-000) into the compartment, and press it into place so that the adhesive sticks to the housing all the way around its perimeter.

9. Grasp an edge of the protective paper and peel it off. Discard it.

10. Inspect the rubber seal (PN: M03-2004-000), and if it is damaged or cracked, replace it.

11. Align the rubber seal with the LEL filter over the waterproof membrane filter. When it is aligned, press it down to make sure it sticks to the adhesive.

12. Replace the cover and tighten the screws.

13. Turn on the instrument and calibrate it before placing it back into service.
