6.4. DMM – MULTIMETER FUNCTION
In this function, the instrument shows the RMS and DC values of voltages between the
positive (+) and negative (-) pole, between the positive (+) pole and earth connection and
between the negative (-) pole and earth connection, in order to check for the presence of
AC components on input voltages.
1. Position the cursor onto DMM by using the arrow keys
(,) and confirm with ENTER. The display shows the
screen to the side.
DMM 15/10 – 18:04
VPNrms 0 V

VNEdc 0 V
2. Connect the instrument to the PV string to be tested as shown in Fig. 8.
3. The voltage values are shown on the display as illustrated
in the screen to the side.
