6.6.3 Calibration Error
The announcement "Calibration Error"
appears on the display when the calibration
datas are lost (e.g. when the internal battery
is defect).
You can not work with the device any longer
because all functions are locked.
In this case please send the Ohmmeter to
our service dept.

CALIBRATION ERROR
6.6.2 Error status display in the temperature display field
If 80
hex
appears in the error status field S. 2.2 (page 27), the temperature display field S. 1.3 (page 27) also
indicates a hexadecimal number which can be used to evaluate the error.
The following errors can be displayed:
Hexadecimal display
1 -
Cable breakage:
The measurement line for the Pt100 sensor is interrupted or has an excessively
or no Pt100
high impedance, or no Pt100 is connected.
2 - connected
4 -
U-cable breakage: The potential taps (+U, -U) are interrupted, or the line resistance is too high.
8 -
Cable breakage:
The measurement line for the Pt100 sensor is interrupted or has an excessively
or no Pt100
high impedance, or no Pt100 is connected.
connected
10 -
Invalid resistance: The Pt100 might be reverse-connected.
20 -
Invalid temperature: The temperature lies outside the defined range or cannot be calculated.
40 -
15 V power supply: The ± 15 V power supply inside the device is not OK.
As in the error status field, different combinations can also appear in the temperature display field.
