Automatic measurement (Vo/c, Is/c, R
ISO
)
Attention:
Maximum DC power: P ≤ 10 kW, Vo/c ≤ 1000 V, Is/c ≤ 15 A
Do not make measurements at PV strings which are connected in parallel!
1. Connect the BENNING PV 1-1 to the PV generator as shown, by means of
the enclosed PV safety measuring leads and the red 4 mm safety test lead.
2. The open-circuit voltage (Vo/c) is automatically displayed.
3. In case of reversed polarity of the DC voltage, the symbol
is displayed and
the measurement will be blocked.
4. Use the
V
ISO
-key to select 250 V, 500 V or 1000 V insulation test voltage.
5. Press the
Auto
-key to automatically measure short-circuit current (I
S/C
) and
insulatio
n resistance (R
ISO
).
Note:
The red 4 mm safety measuring lead is required for the insulation resistance
measurement.

AC/DC current measurement
1. Disconnect all safety measuring leads from the BENNING PV 1-1.
2. Connect the BENNING CC 3 (option) current clamp adapter to the 4 mm test
sockets.
3. Select the 40 A range on the BENNING CC 3.
4. Press the null balance key (ZERO) of the BENNING CC 3 for approx. 2
seconds.
5. Press the

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