Notes
Insulation resistance greater
than 100 MΩ. Measuring
leads not connected or
misconnected
Insulation resistance less
than 10 kΩ. Measuring leads
short-circuited or for two-pole
measurement-central
selector in wrong position.
Loop resistance greater than
200 Ω
Short-circuit current can not
be computed
Computed short-circuit
current greater than 9,99 KA.
also possible in
combination with R S , I K , U N .
Limits of computation for
contact voltage exceeded. R s
> 50 Ω; sonde voltage can
not be measured, possibly
greater than 50 V.
Not all three wires (L 1 , L 2 ,
L 3 ) carry a voltage greater
than 20 V. There is no rotary-
field-dependent phase shift
between L 1 , L 2 , L 3.
No compensation is being
performed, resistance to be
compensated is greater than
5 Ω. Measuring leads not
connected.
Measured resistance greater
than 1 kΩ. Measuring lead
not connected
