No display.
The external fuse for the supply
voltage has triggered.
Replace fuse.
No current display.
Measurement voltage is not
connected.
Connect the measurement voltage.
Measurement current is not
connected.
Connect the measurement current.
The displayed current is too high
or too low.
Current measurement in the wrong
phase.
Check and correct the connection
if necessary.
Current converter factor is incor-
rectly programme
Read and program the current
converter translation ratio on the
current converter.
The displayed voltage is too low
or too high.
Measurement in the wrong phase.
Check and correct the connection
if necessary.
The voltage converter is incorrectly
programmed.
Read and program the voltage
converter translation ratio on the
voltage converter.
The displayed voltage is too small.
Measurement range exceeded.
Use a voltage converter.
The voltage peak value at the
measurement input has been
exceeded by harmonics.
Caution!
It is compulsory to check
that the measurement inputs are
not overloaded.
The active power is too low or too
high.
The programmed current converter
translation ratio is incorrect.
Read and program the current
converter translation ratio on the
current converter.
The current path is allocated to the
wrong voltage path.
Check and correct the connection
if necessary.
The programmed current converter
translation ratio is incorrect.
Read and program the voltage
converter translation ratio on the
voltage converter.
