3. Instrument operation

3.1 Start up

Press the reset for several seconds, the instrument begin to measure

The display should indicate GAMMA and Ready to use

The instrument display four number.

Left up: dose rate

Right up: particles

Left down: average dose rate

Right down: level

3.2 Reset

The instrument begin to measure again, when the reset button be depressed.

3.3 Turn Off

Press the reset button for several seconds to turn off.

3.4 Battery discharge

If the battery voltage is lower than 9V, the indication “LOW BAT”appears on the display, calling for battery replacement.

4. Measurement

● The dose rate value to be given will then the average of which should be read off at a constant rate in sequence.

● The instrument emits a warning sound as soon as the measured value exceeds the level value.

5. Maintenance

● The storage area must be dry and free from corrosive gases.

● The instrument may only be stored with batteries removed.

● The instrument should be protected from dropping and impact.

Sino-Russian joint venture. χ, γ personal dosimeter, dose rate, dose equivalent, average dose rate, alarm threshold ，the four parameters display on the screen at the same time without switching.
