Beeper sounds the alert

Timer :

Can set sampling periods of 1 minute to 40 hours

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

Count Light :

Red LED flashes with each count

Audio :

Beeper chirps for each count (can be muted)

Ports :

• Output: Stereo 3.5mm jack sends counts to computers, data loggers, other CMOS-compatible devices, earphones,

and educational data collection systems. 0-9 V, 1 kOhm impedance.

• Input: 2.5 mm monojack provides calibration input. 0-3.3 V,> Sµs width, rising edge triggered

Anti-Saturation :

Readout holds at full scale in fields up to 100 times the maximum reading
