How it works?

The GQ-SE Geiger Counter installed a Geiger tube to detect radiation.

When the radiation passes through the Geiger tube, it triggers electrical pulses for the CPU

to register as count. The basic count rate unit is CPM (Count Per Minute). The CPM count

rate indicates the radiation level and it can be converted to other traditional radiation units,

such as uSv/h or mR/h.

After GMC-SE is turned on for one minute, it will show the background radiation reading.

The background radiation reading (in CPM) indicates the nature radiation detected at that

minute. This reading may change from time to time and location to location. To get an

accurate reading, user may need to get an average value over a longer time period.

Caution

1. Avoid doing measurements when the battery is low.

2. Do not get the Geiger counter wet. Use a sealed plastic bag to avoid moisture.

2. Avoid doing measurements in direct sunlight.

3. Avoid directly contact with the radioactive material. Use a sealed plastic bag if needed.

4. Turn off the unit when not in use.

5. Keep it in a protective pouch after use.
