Safety and operational considerations
9
When an insulation resistance measurement has been performed on a capacitive
object, automatic discharge may not be done immediately! The warning message
and the actual voltage are displayed during discharge until voltage drops below
10 V.
Continuity functions
Continuity measurements should only be performed on de-energized objects!
Parallel loops may influence on test results.
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, Insulation resistance of PV systems
Insulation resistance:
If a voltage of higher than 30 V (AC or DC) is detected between test terminals, the
insulation resistance measurement will not be performed.
Insulation resistance of PV systems:
Different pre-tests are carried out. If conditions are proper and safe the
measurement will be continued.
Otherwise
or
or
message is displayed.
The instrument automatically discharge tested object after finished measurement.
A double click of TEST key starts a continuous measurement.
Continuity functions
If a voltage of higher than 10 V (AC or DC) is detected between test terminals, the
continuity resistance test will not be performed.
Compensate test lead resistance before performing a continuity measurement,
where necessary.
RCD functions
Parameters set in one function are also kept for other RCD functions!
