Specifications
DETECTOR: may be Geiger-Mueller (GM), scintillator, or proportional
ALARMS: count rate, exposure/dose, and scaler alarm setpoints adjustable over the display range
OVERLOAD: high count rate saturation protection prevents false display of lower count rates
LOSS OF COUNT ALARM PROTECTION: after preselected time interval (default 60 seconds) of no pulses from detector, audible and visual
alarms will be activated
LCD DISPLAY: 3 digit LCD with large 20 mm (0.8 in.) digits, (k)cps, (k)cpm, (k)Bq, (k)dpm, (μ)(m)R(/h), (μ)(m)Sv(/h), low-battery indicator, MAX,
ALARM, AUDIO
DISPLAY RANGE: 0.0 cps to 99.9 kcps; 0.00 cpm to 999 kcpm; 0.00 Bq to 99.9 kBq; 0.00 dpm to 999 kdpm; 0.00 μR/h to 999 R/h; 0.00 μSv/h to
999 Sv/h. Max Display can be set to limit display to calibrated range
BACKLIGHT: built-in ambient light sensor automatically activates LED backlight, unless internal dipswitch is set to continuous-On (will
reduce battery life)
USER CONTROLS:
• ON/ACK - press to turn ON, tap to acknowledge alarms and silence alarm tone, press to reset Sigma Audio alarm, hold for OFF
• MODE - alternates between NORMAL (count rate), MAX (captures peak rate), and COUNT (user-selectable preset count time from 0 to
10 minutes). Number of modes can be reduced in setup.
• DETECTOR: selects active detector
• UNITS - changes the units between count rate (cpm, cps), dose/exposure (μSv/h, mR/h), or disintegration (dpm, Bq)
RESPONSE TIME: user-selectable from 1 to 60 seconds, or Auto-Response Rate FAST or SLOW
AUDIO: greater than 75 dB at 0.6 m (2 ft), approximately 4.5 kHz
POWER: four alkaline or four rechargeable “AA” batteries (instrument does not support in-device charging)
BATTERY LIFE: approximately 500 hours (as low as 100 hours with backlight configured for continuous-on), 16-hour low battery warning
CONSTRUCTION: high-impact plastic with water-resistant rubber seals and separate battery compartment
TEMPERATURE RANGE: -20 to 50 °C (-5 to 122 °F), may be certified for operation from -40 to 65 °C (-40 to 150 °F)
ENVIRONMENTAL RATING: NEMA (National Electrical Manufacturers Association) rating of 4x or IP (Ingress Protection) rating of 53
PHYSICAL: SIZE: 16.5 x 11.4 x 21.6 cm (6.5 x 4.5 x 8.5 in.) (H x W x L); WEIGHT: 0.9 kg (2.0 lb)
