Setting the date and the time

The BENNING PV 1-1 is equipped with an integrated real-time clock which automatically adds
a date / time stamp to each storage process or storage location (see chapter 8.7 "Measured
value memory").
To set the date and the time, carry out the following steps:
- Switch the BENNING PV 1-1 off by simultaneously pressing the
3 .
- Press and hold the
- The date / time format is displayed as follows:
MM.DD = month (1-12).day (1-31)
YYYY = year
HH.mm = hours (0-23).minutes (0-59)
SS = seconds (0-59)
- Press the -key 2 to select a date / time field.

Every change resets the field for the seconds to zero.
- Switch the device off by simultaneously pressing the
the setting.
8.1.4

Testing the battery condition

During switch-on and operation, the BENNING PV 1-1 carries out an automatic battery test.
Discharged batteries are indicated by a battery symbol P on the LC display 1 . As soon as
the battery symbol is flashing, the batteries have to be replaced immediately (see chapter 9.4,
"Battery replacement").
8.1.5 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 .
NULL
m
Measuring lead resistances can be compensated by up to 10 ohms.

Neither the positive nor the negative pole of the PV generator must be earthed!
If a voltage of > 30 V is applied to the test object, the determined voltage will
be displayed. If the measuring voltage at the probe tips exceeds 30 V, the

For single measurement:
- Make sure that the switching circuit and/or the test object are free of voltage.
