Safety and operational considerations
8
All normal safety precautions must be taken in order to avoid risk of electric
shock while working on electrical installations!
Warnings related to safety of measurement functions:
Insulation resistance
Insulation resistance measurement should only be performed on de-energized objects!
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 are displayed during discharge until voltage drops below 30 V.
Do not connect test terminals to external voltage higher than 600 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 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
The standard three-wire test lead, schuko test cable or Plug / Tip commanders can be
used for the insulation test with voltages ≤ 1kV.
The special two wire 2.5 kV test lead must be used for the insulation test with 2.5 kV. (MI
3102H BT only).
If a voltage of higher than 30 V (AC or DC) is detected between test terminals, the
insulation resistance measurement will not be performed.
The instrument automatically discharge tested object after finished measurement.
A double click of TEST key starts a continuous measurement.
