Error
number
Error message Probable cause Potential solution
0 Fatal Error RAM – Replace digital board
1 Fatal Error ROM – Replace digital board
2 Fatal Error EEPROM The parameter set has been diag-
nosed as faulty. Error check is car-
ried out by comparison with a redun-
dant parameter set.
Turn Uni-Probe off and on again.
Parameters will be reset to standard
values. If the error message is dis-
played anyway, then you have to
replace the EEPROM or the entire
digital board.
3 Error CPU Clock The clock frequency of the CPU devi-
ates from the target value. The func-
tion of the measurement 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 complete electronics set
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.
Replace electronics module
8 Warning Change 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 Temperature outside range Ambient temperature too high Replace detector and use water
cooling. Detector is probably
destroyed.
10 Analog Front End Error The actually generated threshold
value for control does not corre-
spond to the default value.
Replace electronics module
11 Error Control Counts Strong pulse rate increase in the
control channel.
Replace electronics module
12 No Control Count Rate Pulse rate in control channel too low. Replace electronics module
13 Watchdog Reset Electrical trouble or error in the elec-
tronics 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.
