Insulation of measurement leads
Insulation of measurement leads may deteriorate over time. This can cause
measurement and/or safety related problems. If insulation material leaks current
measured results will be wrong. Also in such case there is a risk of electric shock when
the user touches deteriorated part of insulation.
Eurocheck is not needed to perform this test.
Step Action
1 q Switch on the tested instrument and select insulation measurement with
1000 V test voltage (highest available).
2 q Connect universal test cable to the instrument. Make sure that all
measurement leads are in direct connection to each other over the
whole length.
q Leave all leads open.
3 q Start insulation measurement. The instrument must signal over-range
measurement result.
4 q If the instrument measures lower-than-maximum insulation, stop
using this measurement cable immediately.
Note:
q It is possible to verify other types of measurement cables as well. Just connect
them to the instrument and perform insulation measurement as described above.
4.14 PE test terminal operation verification
Warning:
q This test uses voltages that are hazardous live. Only adequately trained
personnel may perform this test. Ensure that disconnected lead is not exposed.
Verification can be performed with universal test cable only.
Step Action
1 q Connect tested instrument into Eurocheck RCD/Fault loop output using
universal test cable (use test tips).
q Connect only PE and N leads into L and N sockets respectively.
2 q Switch on the tested instrument and select fault loop impedance, line
impedance or RCD function.
3 q Connect Eurocheck into mains wall socket and enable RCD/Fault loop
output.
q If Eurocheck signals incorrect L and N polarity, reverse connection.
4 q Touch PE terminal on the tested terminal with your finger – the
instrument must signal dangerous line situation.
q Write down test result for documentation purposes.
5 q If test fails the tested instrument is damaged. Send it immediately
to your distributor or manufacturer for repair.
