Procedure in case of error
Possibility of error Cause Help
No display External fuse for the power supply has
tripped. Replace fuse.
No current display Measurement voltage not
connected. Connect measurement voltage.
Measurement current not connected. Connect measurement current.
The displayed current is too large or too
small. Current measurement in the wrong phase. Check and correct the connection if
necessary.
Voltage transformer factor incorrectly
programmed. Read and program the current transformer
ratio on the current transformer.
The peak current value
at the measurement input was exceeded
by current harmonics. Install current transformer with a higher
current transformer ratio.
The current at the measurement input was
exceeded. Install current transformer with a lower
current transformer ratio.
The displayed voltage is too small or too
large. Measurement in the wrong phase. Check and correct the connection if
necessary.
Voltage transformer incorrectly
programmed. Read and program the voltage transformer
ratio on the voltage transformer.
The displayed voltage is too small. Metering range exceedance. Use voltage transformer.
The peak voltage value at the
measurement input was overwritten by
harmonics.
Attention! It must be ensured that the
measurement inputs are not overloaded.
