CAUTION
Upon pressing the GO/STOP key, different error messages can be displayed
by the instrument (see § 6.6) and, therefore, the test cannot be started. Check
and eliminate, if possible, the problem causing the error message before going
on with the test.
4. Press GO/STOP to start the test. In case no error
conditions occur, the instrument displays the message
“Measuring…” as shown in the screen to the side.

5. When measurement (with a fixed duration of 10s) is
complete, the instrument provides the values Ri (+) and
Ri (-), respectively the insulation resistance of the
Positive and Negative poles of the PV field being tested.
If both results are higher than the minimum limit set, the
instrument displays the message “Outcome:OK”;
otherwise, it displays the message “Outcome: NO” as
shown in the screen to the side.
6. Press the SAVE key to store the test result in the
instrument’s memory (see § 7.2) or the ESC/MENU key
to exit the screen without saving and go back to the main
measuring screen.
