CAUTION
The message on the display means that the instrument is discharging
eventual capacitors. During this phase never disconnect nor touch test leads.
Nominal test voltage
value
9. At the end of the test the instrument
automatically discharge eventual capacitors
and parasite capacitances present among
the conductors involved in the
measurement
10 At the end of the test a screen similar to
this is displayed

Nominal test voltage
value
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
