Making measurements with the BENNING PV 1

8.1 Preparations for making measurements
Operate and store the BENNING PV 1 only at the specified storage and operating temperatures
conditions. Do not permanently expose the device to sunlight.
- Check rated voltage and rated current details specified on the safety measuring leads.
- Strong sources of interference in the vicinity of the BENNING PV 1 can lead to unstable
readings and measuring errors.
Before starting the BENNING PV 1, always check the device, the leads and the
m
test object for damages.
8.1.1 Switching the BENNING PV 1 ON/ OFF
- Press and hold the keys 2 and 3 for approx. 2 seconds to switch the BENNING PV 1 on.
Acoustic signals confirm that the device is switched on. Press the keys again for approx. 2
seconds to switch the device off.
- After approx. 2 minutes, the BENNING PV 1 switches off automatically (APO, Auto Power-
Off). It switches on again when the keys 2 and 3 are pressed. An acoustic signal indicates
that the device has switched off automatically.
8.1.2 Testing the battery condition
During switch-on and operation, the BENNING PV 1 carries out an automatic battery test. Dis-
charged batteries are indicated by a battery symbol P on the LC display 1 . As soon as the bat-
tery symbol is flashing, the batteries have to be replaced immediately (see chapter 9.4, "Battery
replacement").
8.1.3 Compensation of the measuring leads (null balance)
In order to carry out a compensation (null balance) of the measuring lead resistance, connect the
measuring leads with each other by means of the alligator clips and press the
symbol C is shown on the LC display 1 .

Measuring lead resistances can be compensated by up to 10 ohms.
