INDICATED USE: Low level (microR) gamma radiation survey
ALARM: The analog ratemeter has a dual action alarm:
1. A fixed alarm point that can be set at any point from 10% of full scale to full scale, and is indicated by a constant audible tone, and the lamp turning on.
2. A quick deviation alarm that is based on background radiation levels. When the instrument is turned on, it takes an 8 second measurement of background radiation levels and determines a deviation alarm setting. If the radiation level exceeds this setting, the alarm audio will beep every 1/8 second, and the lamp will flash.
RESET: Push button to zero meter, and also re-accumulate background data and recalculate the alarm point.
BATTERY LIFE: Typically 600 hours with alkaline batteries (battery condition can be checked on meter)
DETECTOR: 6" diameter x 1" thick (15.2 x 2.5 cm) plastic scintillator
SENSITIVITY: Typically 2000 cpm/uR/hr (¹³⁷Cs gamma)
METER DIAL: 0 - 1 uR/hr, BAT TEST (others available)
RANGE MULTIPLIERS: X1, X10, X100, X1000
ENERGY RESPONSE: Energy dependent
HIGH VOLTAGE: Fixed based on detector
WEIGHT: 8.5 lbs. (3.9 kg) including batteries
