GAMMA Χ-γ Personal Alarm DosimeterOperating Manual1. IntroductionThe GAMMA Χ-γ Personal Alarm Dosimeter is a precision instrument designed to provide reliable personal safety.2. Specifications● Measurement range: 0.01—9.99μSv/h● Detector type: CBM-20-1 metal counter tubes● Energy response: better than + or -25% (relatively Cs-137)● Survey cycle: 30s● Temperature range:-10℃—40℃● Dimensions: 130mm × 70mm × 26mm● Weight: 0.12kg (including battery)● Power supply: One 9V battery● Humidity: 25℃ (95%)● Sound intensity: 85 dB3. Instrument operation3.1 Start upPress the reset for several seconds, the instrument begin to measureThe display should indicate GAMMA and Ready to useThe instrument display four number.Left up: dose rateRight up: particlesLeft down: average dose rateRight down: level3.2 ResetThe instrument begin to measure again, when the reset button be depressed.3.3 Turn OffPress the reset button for several seconds to turn off.3.4 Battery dischargeIf 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.
