Critical error
Description
Action
Battery critical
The battery level is so low that the radiological
performance of the PED cannot be guaranteed. The
PED shuts down 10 seconds after a battery critical
warning. To preserve the internal clock, do not
switch on the PED before recharging.
Recharge the battery.
Calibration
Calibration factors are outside normal range.
Return the PED to Tracerco.
Clock failure
Real-time clock failure. Could be the result of
completely flat battery.
Use DoseVision™ to reset the real-
time clock. After resetting the clock,
ensure that the PED time corresponds
to the computer time running
DoseVision™.
Detector failure
If no counts are recorded over 2 minutes (standard
range) or 8 minutes (extended range), the PED
assumes that the GM tube has failed. Also, for the
extended range only, after 4 minutes the dose rate
reading flashes to indicate low background and
warn of a possible failure of the GM tube.
Return the PED to Tracerco if normal
levels of background radiation were
expected.
Error
Undefined error.
Return the PED to Tracerco.
Memory full
Memory is 95% full. When the memory is
completely full, the PED continues to measure and
display the accumulated dose, but date and time
information is not recorded.
Transfer data to DoseVision™.
System failure
The PED is not working correctly.
Return the PED to Tracerco.
