10 Error message, troubleshooting
10.1 The display is off
Note:
The L or N conductor connection is probably not OK.
If the mains is OK, the internal fuse may have blown.
10.2 Touch current measurement shows 0.000 mA
That is not an error, it is the normal status.
10.3 Touch current measurement over 0.5 mA
Attention! There is voltage present at the touchable conductive parts!!!
Disconnect the test object from the mains socket immediately!!!
Make an insulation resistance measurement between the touchable conductive parts and the test object’s
mains connection (L1/L2/L3/N). All switching elements must be closed during the insulation
measurement, so that all insulations are reached.
The measured value must be over 2 MΩ. Measure the touch current after a successful insulation
measurement. The measured value must be less than 0.5 mA.
10.4 Differential current measurement shows ‘F’
The device determines the limit value of the differential current based on the total heat output. There is a
limit value of 1 mA/kW total heat output.
Check the total heat output of the test object (rating plate).
If the performance specifications of the test device and rating plate of the test object are identical, the
insulation properties of the test object are not OK!
Disconnect the test object from the mains connection.
Use an insulation meter to look for the fault. The mains voltages are not displayed correctly.
Check the mains voltage with a measuring device. If the fault is due to the test device, the test device must
be sent to the service department or replaced!
