Before taking an insulation
measurement, the instrument
measures voltage on the system under
test. If it detects voltage in excess
of 25V and you attempt to take a
measurement, the instrument displays
the message shown to the left, and no
measurement is taken.
You must eliminate the voltage to
resume taking the measurement.
If during an insulation measurement
the value to be measured exceeds the
measurement range (which depends
on the test voltage), the instrument
G
reports this condition. For example, the
screen to the left is displayed when the
range is exceeded while measuring in
the 100V range.
