Operational display ranges are dependent on the detector and dead time configuration. The minimum and maximum display can be set to limit the display to the calibrated range.

Backlight: Built-in ambient light sensor automatically activates LED backlight unless internal dipswitch is set to continuous-on

User Controls: 

ON/AUD: Extra-long press to turn ON; Short press to adjust audio level; Extra-long press plus 3 seconds to turn OFF

UNITS: Short press Changes the units between count rate, dose/exposure, or activity

DETECTOR: Short press to change active external detector to the next enabled detector. On 3003i, extra-long press to switch between internal and external detector.

MODE: Short press alternates between modes: RATE (displays count rate), MAX (captures peak rate), COUNT (user-selectable preset count time from 0 to 31.68 years), and DOSE (current accumulated dose)

ACK/RST: Short press to acknowledge alarms, extra-long press to reset current mode

LOG: Short press to log current display (requires Lumic Data Logger Kit) or initiate count in COUNT mode, extra-long press to change count in COUNT mode

PRG: Short press in first 4 seconds of power-up will grant access to setup menu

Response Time: User-selectable from 1 to 60 seconds, auto SLOW, auto FAST, fixed SLOW (22 s), fixed FAST (4 s)

Alarms: Three count rate, exposure/dose, scaler, and accumulated dose alarm set-points adjustable over the display range

Self-Diagnostics: Detects and reports internal instrument issues, indicated by graphic FAULT display and audio warning

Overload Protection: High count rate saturation protection prevents false display of lower count rates. OVERLOAD will appear on the display and an audio warning will be triggered.

Loss of Count Protection: After a user-defined time, typically 60 seconds, with no pulses from detector, the unit will flash a zero reading, an audio alarm will be triggered, and LOSS OF COUNTS will appear on the display

Overrange: If reading should exceed the predefined detector range, the unit will flash a maximum reading, an audio warning will be triggered, and OVERRANGE will appear on  the display

Audio: "Click" audio greater than 65 dB at 0.6 m (2 ft.), Alarm audio greater than 72 dB at 0.6 m (2 ft.), approximately 4.5 kHz

Calibration Protection: Internal dipswitch to disable front-panel calibration parameter changes

Power: Four "AA" batteries

Environmental Rating: NEMA rating of 3x or IP rating of 53

Size (H x W x L): 16.5 x 11.4 x 21.6 cm (6.5 x 4.5 x 8.5 in.)

Weight: 0.9 kg (2.0 lb) (excluding detectors and clips)
