6.6. Error status display
6.6.1 Error status display in the error status field
In the event of an error, a corresponding error status appears in status line 2 (page 27) of the display field S. 2.2.
Hexadecimal display
1 -
MI-Over:
Measurement current too high (in the 20-mV mode) or
test-object resistance / line resistance too high.
2 -
MU-Over:
Measuring amplifier for the potential taps is ( +U, -U) overdriven.
4 -
I-Over:
Test-object resistance / line resistance too high.
I-cable breakage
e.g. I-cable breakage, or resistance too high in the 20-mV mode.
8 -
Overdrive:
Drive limits of the internal A/D converter have been exceeded.
10 -
Underdrive:
Drive limits of the internal A/D converter have been fallen short of.
20 -
I not constant:
Measurement current has not settled; this can occur in the case
of inductive test objects. The test object might not be measurable,
due to an excessively high inductance or time constant T = .
40 -
U-cable breakage: + U, -U-line resistance too high, or no contact with the test object.
80 -
Temperatur
compensation:
Error in temperature compensation, check external sensor.
Different combinations can appear in the hexadecimal display. For example:
22 -
(20+2)
Measurement current has not settled, as the inductance of the
test object might be too high, and the measurement amplifier of
the potential taps (+U,-U) is overdriven.
A -
(2+8)
The measurement amplifier for the potential taps is overdriven and
the drive limits of the internal A/D converter have been exceeded.
18 -
(10+8)
In the case of overdrive or underdrive, the voltage supply in
the measurement section is not OK.
