CPS: pulse times per second (In the pulse rate model, pulse has constantly been measured by counter tube and translated into pulse rate)
CPM: pulse counts per minute(ln the pulse rate model, pulse has constantly been measured by counter tube and translated into pulse rate

International Safe Icon
It show that operation must comply with the requirements of the specification Nuclear radiation icon, it warns that people must be careful and operate as instructions when getting close to the radiation source.

Operation instruction

α, β, y, X ray selection switch
The multi-function digital nuclear radiation scanner adopts high precision Geiger counter tube, reliably measures not only y rays, but α, β, and X rays as well. By the ray select rotation switch, we can select the measuring rays by choice

1. Switch to the middle for detecting the y ray.
2. Switch to the left for detecting y + β ray.
3. Switch to the right for detecting α + y+ β ray.
4. Switch at any position, it can detect X rays. When switch to the middle, α, β rays will be blocked unless the scanner is veryclose to the radiation source.

Attention: Be careful when rotating the switch to avoid damage to the sensor.
Under normal conditions, the meter can detect the current radiation value quickly and accurately when the sensor window of rays aim at radiation source.

Power source and back light switch button.
Note: The stored data will still be saved after turn it off, but the stored data will be lost if it is turned off Inappropriate.

1. Press the switch button for 2 seconds, it will beep shortly, and ac-tivate the LCD display; Press again the switch button for 2 seconds to shut down the LCD display.
2. After turn it on, and press the switch button, the LCD back light will be activated, press again, the back light will be shut off. To save energy, the back-light will be automatically shut off 1 minutes after be activated.

Sv/h and Rem/h button for current radiation dose rate

1. Press the button and into standard mode, it displays the current measurement value (µSv/h). The measurement results could be read in data mode, and bar graph as well. The bar graph on the lower corner of display will change as the reading fluctuating and is distributed in scales as 0.1,1,10,100. Note: If the reading is too low, the bar graph will be show in a line.
2. Sv/h and Rem/h unit conversion
   Press the button for conversion, which is based on the formula: 10µSv/h = 1mRem/h

Sv Dose accumulation
The digital nuclear radiation scanner could also do the measure-ment, recording the accumulated radiation dose at specific time. The initial unit is µSv, and it will automatically convert to mSv or Sv as the measured dose rate getting higher.

Button for Dose Rate accumulation

1. Press “SV” button, and enter into the regular infinite dose rate accumulation calculation mode with dose rate icon ( µSv ) on the display. Press the button again, and enter into timing measurement mode (default value is 60 minutes). Press the button once again to stop the timing measurement mode with a beep warning, and it dis-plays the current accumulated measurement value; Press the button one more time, it will return to regular infinite dose rate accumulation calculation mode.
2. Under the timing measurement mode, press this button for 2 seconds for setting the measuring time, then it displays dose icon (µSv) and time unit icon “min”. Now, the display will indicate 3 numbers as 060 as default value, which means 60 minutes, and the maximum is 999 minutes.

The first digit(the hundreds) will be in flashing state for setting directly .

Once the measurement time is set, there will be a short beep sound as remind at the end of the measurement. It displays dose accumu-lative value at that time, and the TIME icon shows and stops flash-ing. If it is not coming to the timing time yet, press “SV” button into non-timing accumulation state or recording state. if long press this button, you will re-enter into the timing setup mode .

Two methods for stopping the measurement:
Under non-timing condition, short press “SV” button for the 2nd time, stops the accumulate measurement, and into timing measurement; during the process of the timing measurement, short-pressing this button will stop accumulative measurement state. Choosing other operation mode to zero the measurement results.

Pulse counting
The multi-function digital nuclear radiation scanner can be also used as an ordinary Geiger counter. Under the setting, it only records re-ceived pulse and calculate pulse, it will not be switched to Sv ( Dose equivalent unit, 1Sv = 100Rem ) . The meter shows the received accumulative value of the pulse on LCD.

Pulse counting measuring button

1. Pulse Rate Value Indication ( CPS/CPM )
   In radiation ray pulse rate testing mode, radiation ray pulse is con-stantly measured by counter tube and then transfer into pulse rate. Press “CPS/CPM” button once and then press the button again into pulse rate unit switch between CPS and CPM.

   • CPS: pulse number per second
   • CPM: pulse number per minute

2. Press “CPS/CPM”key for the 3rd time into pulse counting mode, and it will display the pulse icon. Press the”CPS/CPM” button again (the 4th time) to end pulse counting. There will be a beep sound as a remind of entering into timing pulse counting mode, and shows the pulse and timing flashing icon on display; press this button again to stop pulse counting; pressing once again will return to CPS pulse counting function.

3. Long press “CPS/CPM” button for two seconds or under “pulse” measurement mode, and will enter into measuring time setup mode, and the screen shows “pulse” and “time” icon. At this time, the dis-play shows three digits, default value is 060, means 60 minutes, max to 999 minutes, and the first digit(the hundreds) is in blinking state, and this value can be set directly.

If measurement time is set, there will be a short beep sound at end of the measurement. By then, it will display the measured accumulative value at that time. Meanwhile, the TIME icon will be shown and stops flashing.

Two methods for stopping the measurement:
Under not-timing condition, short press “CPS/CPM” pulse button for the 4th time, end of the accumulative measurement, and into timing measurement; during the timing measurement, short press this but-ton to stop the accumulative measuring state.
Choosing other operation mode, then measuring results disappear.

Menu setup
Press “setup” button into menu setting interface: Date, time, alarm, pulse volumn , average time set(T), Bluetooth wireless data trans-mission(BT); 1 minute after press the button and left it untouched, it will automatically return to “µSv/h” measurement mode.

• Date format: year, month, day
• Time format: hour, minute, second
• Alarm threshold: 1-999µSv/h, default value 205µSv/h
• Pulse sound: ON/OFF

Time setting for average radiation measurement: the setup can change the processing reaction time of the meter against radiation source with setup range from 8s to 120s. With the increasing of radi-ation dose rate, it will automatically and proportionally reduce the av-erage time according to the current setting average time. When the setting time is 8s and the radiation strength is more than SµSv/h, the fastest response time can reach is 2s. Factory default time is 30s.
Bluetooth data transmission: “ON” and “OFF”.
