Also displays time remaining from 19:59 to 00:01 (in hh:mm format)
Gamma Response: Typically 1800 cpm per mSv/hr
Alerts & Alarms: Radiation alarms are adjustable over entire range. There are distinct alerts and alarms for exposure and accumulated dose:
Dose rate alert
Dose rate (hi)
Accumulated dose alert
Accumulated dose (hi)
Time remaining to allowed dose (hi)
Detector failure alert
Low-battery notice when only 8 hours remain
Loss of Count Protection: If no pulses are received from the detector in 60 minutes, instrument failure is indicated by an audible and visual alarm and the display alternating between "0.0" and "F"
