Warnings related to measurement functions
Insulation resistance
 Insulation resistance measurement should only be performed on de-energized
objects!
 When measuring the insulation resistance between installation conductors, all
loads must be disconnected and all switches closed!
 Do not touch the test object during the measurement or before it is fully
discharged! Risk of electric shock!
 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 is displayed during discharge until voltage drops below
10 V.
 Do not connect test terminals to external voltage higher than 550 V (AC or DC) in
order not to damage the test instrument!
Continuity functions
 Continuity measurements should only be performed on de-energized objects!
 Parallel impedances or transient currents may influence 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
 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, where necessary, compensate test
lead resistance.
