Personal Dose Alarm Meter DP802i Radiation Monitoring Devices in Big Display 30x40mm
Purpose of use
Measurement of personal gamma and x-ray radiation equivalent dose rate(EDR)
Measurement of personal gamma and x-ray radiation equivalent dose (ED)
Alarm of exceeded programmed threshold levels
DP802i X-γ Radiation Personal Dose Equivalent (rate) Monitor is a precision instrument, please pay attention to protect, the following suggestions will be conducive to the instrument maintenance and prolong service life.
Storage and use process should stay as dry as possible, excessive moisture will cause damage
Don't drop, or violent vibration, otherwise it will cause damage to the detector.
If long time no use, please take the battery out.
1,Safety Operation Specification
DP802i X-γ Radiation Personal Dose Equivalent (rate) Monitor is mainly used for
gamma rays, X rays and hard beta radiation protection monitoring, suitable for nuclear power plant, the accelerator, isotope applications, industrial X-ray, gamma NDT, radiation therapy,
cobalt gamma irradiation, radioactive laboratory, nuclear facilities around the environmental monitoring field, timely alarm indicator, ensure the safety of workers, The instrument can be measured simultaneously dose rate and cumulative dose.
It adopts new chip technology, low power consumption, the detector is compensative GM count, wide measuring range, good energy response characteristics, and fault detection, dose rate overload alarm and protection function.

3,Display Content Description
1). Monitoring Status Display
From Left to Right:
1st line: Battery indicator, alarm, vibration alarm, flashing alarm, time.
Second line:Dose rate, the dose rate was 0.18 uSv/h.
Third line:Radiation area countdown, the setting time for 10 minutes; Cumulative Dose, The cumulative dose uSv 18.0.
2).Query, Status Display
First line: Time(display“:”),Date(display“/”)
Second line: Dose rate alarm threshold, it’s 100uSv/h.
Third line: Stay time (00 say no set); Cumulative dose alarm threshold, it’s 500uSv.
3).Cumulative Dose Query Display
First line: Starting date of accumulative total, it’s Oct.18.
Second line: Starting year accumulative total, it’s the year of 2006.
Third line: The cumulative dose to the current time is mSv 36.8
A Dial wheel button on the left of the instrument,
UP key: Power on, Check settings, Modification Parameter
Down key: Power off, Check total dose, Modification Parameter
Middle key: Backlighting, Setting
Press button up key for 3 seconds, power on instrument into the measuring state, displays information as shown in picture 1.
With button down key for 3 seconds, power off the instrument.
Measurement condition, upward the key, that all the working parameters will be displayed as shown in picture 2.
Measurement condition, press downward key, it will show accumulative total dose and its start time as shown in picture 3.
Press the middle key 3 seconds; enter setup, as shown in picture 3 shows that, the parameters of the flashing said can be modified.
Press the middle key 3 seconds, exit status, or not make any key operation after 10 seconds will quit setup and returns to the measuring condition.
5). Setting Parameter
After entering parameter modification, the corresponding parameters which can be set will shine, then press the upward or downward key to change the value accordingly.
When dose rate alarm threshold flashing, press up and down the thumb wheel key can modify the value of the dose rate alarm threshold, it can be selected in 0.5,1.0,2.5,10,30,50,100 and 500(unit: uSv/h)
When cumulative dose option flashing, press up and down the thumb wheel key can modify the value of the alarm threshold, its can be selected in 0.1,0.2,0.3,0.5,1,2,5,10,20 and 50 (unit: mSv).
Sound, vibration, shine, etc can be chose.
Setting from 0～99 minuets according to customer request.
Set hour, minuets
Set year, month, day
When cumulative dose flashing, press up key or down key to choose whether to clear, 0.00 says to clear, flashing means the current cumulative dose not clear. Choose clear, the system will take the current date as the starting date of the cumulative dose.
Cumulative Dose doesn’t return after clearing
6). Alarm Instruction
Sound Instruction: ring 0.2 Sec., stop 0.8 Sec.
Luminous Instruction: light 0.5 Sec., dark 0.5Sec.
Vibration Instruction: vibration 0.5 sec., stopped 0.5 sec.
In the same time, the alarm mark flashing.
Close the alarm: press any key removes or below alarm threshold or closed alarm prompt.
Sound Instruction: ring 0.5 Sec., stop 0.5 Sec
In the same time, the value of the cumulative dose flashing.
Close: Press the middle key in short time to remove alarm.
Sound Instruction: ring 0.8 Sec., stop 0.2 Sec
Close: Trouble relieved can automatically terminate
Voice: long ring.
Methods: leave off high radiation area can be lifted.
Battery Indicator: empty battery symbol flashing, in the same time, every minute will have a 0.1 sec. “drops” sound. Then it means the batter has insufficient, please replace the battery.
When the battery shortage, instrument will automatically save data and shutdown.
