Error
number
Error message Probable cause Potential solution
0 Fatal error RAM - Replacing the digital board
1 Fatal Error ROM - Replacing the digital board
2 Fatal error EEPROM The parameter set has been diag-
nosed as faulty.
Error check is carried out by com-
parison with a redundant parameter
set.
Turn Uni-Probe off and on again.
Parameters will be reset to standard
values.
If the error message is displayed
anyway, then you have to replace
the EEPROM or the entire digital
board.
3 Error CPU Clock The clock frequency of the CPU has
changed. The function of the mea-
surement is no longer guaranteed.
Replace digital board or complete
electronics.
4 Error Power Fail One of the supply voltages on the
digital board deviates from the tar-
get value. The cause for this devia-
tion may be found in the power sup-
ply or on the digital board.
Replace Replacing the electronics
module
5 Error no count rate Error in the detector part Replace multiplier and/or electron-
ics module
6 Error Wrong HV Error in the detector part Replace multiplier and/or electron-
ics module
7 Error HV deviation The actually generated HV does not
correspond to the default value.
Replacing the electronics module
8 Replace multiplier The mean HV deviates -20% or
+40% from the HV default.
(The mean HV is averaged with a
time constant of 10 days.)
Replace multiplier or multi-
plier-crystal combination.
9 Error temp out of range Ambient temperature too high Replace detector and use water
cooling.
Detector is probably destroyed.
10 Error Analog Frontend The actually generated threshold
value for control does not corre-
spond to the default value.
Replacing the electronics module
11 Error control count rate Strong pulse rate increase in the
control channel.
Replacing the electronics module
12 No control count rate Pulse rate in control channel too
low.
Replacing the electronics module
13 Watchdog Reset Electrical trouble or error in the
electronics
Will only be entered in the error log!
Remove electrical trouble, if neces-
sary, replace the electronics mod-
ule.
14 Hardware reset Error in the electronics
Will only be entered in the error log!
If the error occurs repeatedly, you
have to replace the electronics
module.
