4.1 Dose and dose rate alarm
When an acvated alarm threshold is exceed-
ed, the display is blinking.
In case of an exceeded dose alarm threshold,
the display switches to the dose indicaon
and in case of an exceeded dose rate alarm
threshold to the dose rate indicaon. If both,
the dose and the dose rate alarm threshold are
exceeded, the „Twin“-indicaon is displayed.
In case of a dose rate alarm short constant
acousc warning signals will be triggered. If the
acousc alarm has been acvated in the menu,
the warning signal sounds every second.
Such an alarm can be acknowledged by means
of the -key. Thus, the acousc alarm is swit-
ched o and the menu returns to the selec-
ted standard display. But, the triggered alarm
threshold is sll blinking.
The acousc alarm will be re-triggered as soon
as the measured value falls below an already
acknowledged dose rate alarm threshold and is
then exceeded again.
