CAUTION
The message on the display means that the instrument is discharging
eventual capacitors. During this phase never disconnect nor touch test leads.
8. At the end of the test the instrument
automatically discharge eventual
capacitors and parasite capacitances
present among the conductors involved
in the measurement
Nominal test voltage
value
9. At the end of the test a screen similar to
this is displayed
Resistance value
10. If the resistance value is higher than the
full scale, a screen similar to this is
displayed.
Note! An insulation value higher than
the full scale is an excellent insulation
value, generally much higher than the
minimum requirements prescribed by
standards
Nominal test voltage
value
11. + GO
Press LOCK and GO together to perform the measurement in
continuous mode, the symbol LOCK is displayed. Press GO
another time to stop the continuous mode measurement
12. In lock mode the instrument emits an acoustic signal and the auto power off is
disabled
4.6.1. Measurement time setting mode
Press LOCK more than one
second, a screen similar to this
is displayed
Press the arrow keys to select
the desired time value Setting values
between 2s an 60s
GO
Press GO to confirm the
selected value
4.6.2. Anomalous cases which may occur during M
 tests
If, during measurement, the input voltage
present at terminals is higher than 24V,
the instrument suspends the test.
A screen similar to this is displayed
showing the input voltage value.
