3. At the end of the set duration time, the instrument shows
on the display the maximum value among all the partial
measurements performed and the message "
OK " in case
of a positive result (value lower than the set limit threshold)
or "
NOT OK " in case of a negative result (value higher
than the set limit threshold).

4. Press the SAVE key to store the test result in the instrument’s memory (see § 7.1) or
the ESC/MENU key to exit the screen without saving and go back to the main

2. Connect the alligator clips and/or test leads and/or remote switch probe to the
conductor to be tested as indicated in Fig. 10.
3. Press the
GO/STOP key on the instrument or the START key on the remote switch
probe. The instrument starts the calibration procedure of the cables, immediately
followed by the verification of the compensated value.
CAUTION
If message “ Measuring… ” appears on the display, the instrument is
performing measurement. If message “ Verify ” appears on the display, the
instrument is verifying the calibrated value. During this whole stage, do not
unshort the test leads of the instrument.
4. Once calibration is completed, in case the detected value
is lower than 5

, the instrument gives a double acoustic
signal which indicates the positive result of the test and
displays a screen similar to the one reported here to the
side.
