9.6.3 Error Messages during Calibration
Error
No. Error text
Cause Solution
10
Not calibrated
No calibration coefficient
available or not calculated
- Enter coefficient or calculated it
38 Wrong product
If the product is unequal to
the calibration product when
reading-in the calibration
count rate
- Adapt product to calibration
product
41
min. measuring range not
reached
Enter negative measuring
range
- Check final value
(only with square or cubic curve)
42
max. measuring range
exceeded
Measuring range input lies
above the limit
- Check final value
(only with square or cubic curve)
43
Rate Overflow
With twisted measuring
range
- Check input
47
Check external mass
counter setting
Input is outside the limits
and is ignored.
(triggered when changing
parameters – measuring
range or mass counter)
- Increase step-width of mass
counter or reduce maximum
measuring range
(safety circuit, so relay output
can still follow)
9.6.4 Error Messages during Measurement
Error
No. Error text
Cause Solution
1
Rate Overflow
Count rate
>520.000cps
- Check configuration of applica-
tion, or calculation
2
No Detector Rate
Error in detector - Error in detector
- Multiplier or probe electronics
faulty
3
Wrong HV
HV < 500V or >1500V, out-
side the control range
- Error in detector
- Multiplier or probe electronics
faulty
6
Detector temperature >
65°C
Detector temperature has
exceeded 65°C
- Detector too warm, provide
adequate cooling
7
Trouble with detector
communication
Data transfer between de-
tector and evaluation unit
faulty
- Check connection terminals of
cable
- Detector or evaluation unit
faulty
- Broken cable
9
Detector temperature >
85°C
Detector temperature has
exceeded 85°C
- Detector too hot, provide ade-
quate cooling
44 Current input error
Input current above 23 mA - Check power source
46
Check external mass
counter setting
Input is outside the limits
and is ignored.
(triggered when changing
parameters – measuring
range or mass counter)
- Increase step-width of mass
counter or reduce maximum
measuring range
(safety circuit, so relay output
can still follow)
