to compensate the resistance of the test leads as indicated in §
6.3.2.
CAUTION
Before connecting the test leads, make sure that there is no voltage at
the ends of the conductor to be tested.
Always make sure, before any measurement, that the compensation
resistance value is referred to the cables currently used. In case of
doubt, repeat the calibration procedure described in § 6.3.2.
8. Press the
GO/STOP
key. The instrument will start the measurement.
CAUTION
The message “
