Testing PE terminal
• If phase voltage is detected on the tested PE terminal, stop all measurements immediately and
ensure the cause of the fault is eliminated before proceeding with any activity!
Notes related to measurement functions
General
• The ! indicator means that the selected measurement cannot be performed because of
irregular conditions on input terminals.
• Insulation resistance, continuity functions and earth resistance measurements can only be
performed on de-energized objects.
• PASS / FAIL indication is enabled when limit is set. Apply appropriate limit value for evaluation
of measurement results.
• In the case that only two of the three wires are connected to the electrical installation under
test, only voltage indication between these two wires is valid.
Insulation resistance
• If voltages of higher than 10 V (AC or DC) are detected between test terminals, the insulation
resistance measurement will not be performed.
Continuity functions
• If voltages of higher than 10 V (AC or DC) are detected between test terminals, the continuity
resistance test will not be performed.
• Before performing a continuity measurement, compensate test lead resistance.
RCD functions
• Parameters set in one function are also kept for other RCD functions!
• The measurement of contact voltage does not normally trip an RCD. However, the trip limit of the
RCD may be exceeded as a result of leakage current flowing to the PE protective conductor or a
capacitive connection between L and PE conductors.
• The RCD trip-lock sub-function (function selector switch in LOOP position) takes longer to
complete but offers much better accuracy of fault loop resistance (in comparison to the RL sub-
result in Contact voltage function).
• RCD trip-out time and current measurements will only be performed if the contact voltage in the
pre-test at nominal differential current is lower than the set contact voltage limit!
• The auto-test sequence (RCD AUTO function) stops when trip-out time is out of allowable time
period.
Loop impedance (with Loop RCD option)
• Isc depends on Z, Un and scaling factor
• The current limit depends on fuse type, fuse current rating, fuse trip-out time
• The specified accuracy of tested parameters is valid only if the mains voltage is stable during
the measurement.
• Fault loop impedance measurements will trip an RCD.
• The measurement of fault loop impedance using trip-lock function does not normally trip an
RCD. However, the trip limit may be exceeded as a result of leakage current flowing to the PE
protective conductor or a capacitive connection between L and PE conductors.
Line impedance
• Isc depends on Z, Un and scaling factor
• The current limit depends on fuse type, fuse current rating, fuse trip-out time
• The specified accuracy of tested parameters is valid only if the mains voltage is stable during
