In the operating mode „Sigma-Alarm" (chapter 3.4), as well as
for activated NBR-Alarm (chapter 4.7), the message "Learn-
ing" is displayed together with a progress bar for the first 30 s.
During this time the sigma-alarm level is adapted more quick-
ly to the current radiation level and the reference energy dis-
tribution is determined for the NBR evaluation.
During this time period the sigma alarm is active, however not
yet with the full sensitivity. The NBR-Alarm is not yet active.
In order to avoid erroneous initial parameters, the device
should not be exposed to artificial gamma radiation during this
phase.
Please refer to 'Flow Diagram Background Learning &
Alarming' in chapter 12.2.
Display during the learning phase.
The RadEye is set up.
