(1Gyoptional）

dwell time

0.1s—999sAny value can be set

 subsidiary

Sensor temperature, ambient temperature, battery voltage, high voltage value

overloading characteristic；overload characteristic

10 times more than 100 mGy / h dose rate for long time and overload prompt

angular response

<5% (85% visible, looking up); <10% (15% visible, top up)

Data ups and downs

<1% (one data recorded every 10 seconds (reading interval 10s), 20 consecutive measurements, calculate the dispersion of the data)

ambient temperature

<1% (the data were measured at-25℃, 25℃ and 50℃ for over 4h and calculated discrete)

High temperature and high humidity

<1% (Dose rate of 137Cs point source was measured daily for 15 days for 10℃, 95% relative humidity Read 10 dose rates and average them; find relative standard deviation of 15-day data)

vibration performance

(Refer to Annex E of GB / T8993-1998, the test sample acts with vibration in non-working state,

And after undergoing the test, you need to work normally. The test samples (under packaging

conditions) are in three mutually vertical axes unless otherwise specified by the relevant standards

Vibration on the line (amplitude 2cm, frequency 10Hz, 30min))

Work operation after testing under the above conditions

long term stability

Use 137Cs point source (intensity: the dose rate at 1 meter is 3-5 times the background dose rate

where the instrument is used) for a regular inspection of 3 months Check, each test reading for 10 minutes, the net reading deviation should be within 2%.
