9. AC/DC voltage measurement
1. Disconnect the PV measuring leads from the BENNING PV 2.
2. Connect the red and black safety measuring lead as pictured.
3. The BENNING PV 2 automatically measures the AC/DC voltage at the measu-
ring probes.
4. The polarity of the DC voltage is displayed by “+/-“. In case of AC voltage, “+/-“
will be displayed alternately.
5. Press the -key
