Alarm The Model 192 has a dual action alarm.
1. A fixed alarm point can be set at any point from 10% of full scale to full scale, and is indicated by a constant audible tone, and the lamp turning on.
2. A quick deviation alarm that is based on background radiation levels. When the instrument is turned on, it takes an 8 second measurement of background radiation levels and determines a deviation alarm setting. If the radiation level exceeds this setting, the alarm audio will beep every 1/8 second, and the lamp will flash.
Audio Built in unimorph speaker with ON/OFF switch (greater than 60 dB at 2 feet )
Calibration Controls Accessible from front of instrument (protective cover provided )
Response Toggle switch for FAST (4 seconds) or SLOW (22 seconds) from 10% to 90% of final reading
Reset Push-button to zero meter, and also re-accumulate background data and recalculate the alarm deviation.
