PECIFICATIONS
External Detector: may be Geiger-Mueller (GM), scintillator, or proportional
Internal Detector: one energy-compensated GM tube
Energy Response: within 25% of true value from 60 keV to 3 MeV
Linearity: readings within 10% of true value
LCD Display: three-digit LCD with bar graph, 11 units, five multipliers, two mode icons,
three alarm levels, and four fault messages, as well as USB, wireless, audio, and low-battery
icons
Alarms: three adjustable count rate, exposure/dose, count, and accumulated dose alarm
setpoints adjustable over the display range
Overload Protection: high count rate saturation protection designed to prevent the false
display of lower count rates; if the instrument detects an overload condition, it will display a
graphic OVERLOAD icon and trigger an audio warning
Zero Protection: after typically 60 seconds of no pulses from the detector, unit will flash a
zero reading, the alarm audio will be triggered, and a graphic LOSS OF COUNTS icon will be
displayed
Overrange: if the reading should exceed the predefined detector range, the instrument will
flash a maximum reading, display a graphic OVERRANGE, and trigger an audio warning
Headphone Jack (optional): 1/8 inch stereo jack for use with headphones for audio output.
It will be located to the left of the instrument handle.
Backlight: built-in ambient light sensor automatically activates low-power LED backlight
or backlight level may be user defined, unless internal dip switch is set to continuous-on
(will reduce battery life)
User Controls:
