Averaging Periods: Display updates every 3 seconds, showing the average for the past 30-second time period at normal levels. The averaging period decreases as the radiation level increases. User can select a fast 3-second averaging period.
Timer: Can set 1-10 minute sampling periods in one-minute increments, 10-50 minute sampling periods in 10-minute increments, and 1-24 hour sampling periods in 1-hour increments
Alert: Beeper sounds the alert
User-adjustable alert level is set using three buttons
Accuracy: ± 15% up to 50 mR/hr; ± 20% up to 100 mR/hr
Anti-Saturation: Readout holds at full scale in fields up to 100 times the maximum reading
Temperature Range: -20º to +50º C , -4º to +122º F
Power: One 9-volt alkaline battery; battery life is average 2160 hours at normal background, average 625 hours at 1 mR/hr with beeper off
