Functional Test; Failure Indication; Radeye B20/-Er Db-065 E - Thermo Scientific RadEye B20 Operating Instructions Manual

6. Functional test

When the instrument is switched on, it will show zero count rate,
dose rate or activity until the first detector pulse occurs.
The radiation meter performs continuous self-check routines. A
complete failure of the detector during operation will be indicated
after 1 minute on the LCD and be announced by the beeper. The
same applies to the battery voltage.
6.1 Functional test
To carry out a simple test, shortly press any key. A short audible
pulse has to be released and the LC display is illuminated for
some seconds.
The heart symbol next to the battery indicator must be "beating".
This indicates that the cyclic tasks as calculating measurement
values and checking for alarm thresholds are active.
