7. Press and hold the GO/STOP key for at least 3s in
order to start the test. In case no error conditions occur,
the instrument displays the message “Measuring…” as
shown in the screen to the side. In field “Vtest”, the real
test voltage generated by the instrument is shown. Test
duration may vary according to the presence of stray
capacitances

8. The instrument carries out the following measurements in
a sequence:
 Insulation between positive pole (+) of the string and
earth connection
 Insulation between negative pole (-) of the string and
earth connection
 Calculation of the value of resistance Rp given by the
parallel of measurements (+) and (-)
If “Rp≥Lim”, the instrument shows the message “OK”, to
indicate a positive result of measurement.
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
measuring screen.

“Vtest” to set the test voltage.
3. Use the arrow keys (,) to select one of the following
test voltages (Vnom): 250, 500, 1000, 1500VDC. Please
remember that, in compliance with standard IEC/EN
62446-1, test voltage Vtest must be ≥ rated voltage of the
installation.
