Figure 6: Detector Loss of Count Display (Display Will Also Flash)
Detector Over Max
If the detector exceeds the programmed maximum value for the given unit,
the instrument flashes the maximum value for the currently selected units
and the MAX icon as a warning. Additionally, the ALARM icon is displayed
at the top of the screen and an audio alarm sounds. The user should be
aware that the alarm, including the audio, can only be cleared by removing
the instrument from the radiation field.
Figure 7: Example of Detector Over Max (Display Will Also Flash)
Detector Over Range
If the detector is exposed to high levels of radiation or has an internal
malfunction that causes it to count high or excessively, the unit flashes all 8’s
for the currently selected units as a warning. Additionally, the ALARM icon
is displayed at the top of the screen, an audio alarm sounds (which can be
silenced by the ACK/RST button), and the OVERRANGE icon is
displayed. The user should ensure whether this condition is being caused by
a high radiation field, by a shorted cable, or by internal malfunction.
