Corrective Action
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 parame-
ter 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 dig-
ital board.
3 Error CPU Clock The clock frequency of the CPU
deviates from the target value.
The function 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
target value. The cause for this
deviation may be found in the
power supply or on the digital
board. Replace complete electronics set
5 Error No Pulse Rate Error in the detector part Replace multiplier and/or electronics
module
6 Error Wrong HV Error in the detector part Replace multiplier and/or electronics
module
7 Error HV Deviation The actually generated HV does
not correspond to the default
value. Replacing the 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 multiplier-crys-
tal combination.
9 Error TEMP out of range Ambient temperature too high Replace detector and use water cool-
ing.
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 Counts Strong pulse rate increase in the
control channel. Replacing the electronics module
12 Error No Control Counts Pulse rate in control channel too
low. Replacing the electronics module
13 Error Watchdog Fail Electrical trouble or error in the
electronics
Will only be entered in the error
log! Remove electrical trouble.
If necessary, replace the electronics
module.
