12 Multimeter Functions
12.1 Probe Voltage U
probe
– Max. 300 V
Voltage is measured between the mains PE terminal at the test instrument
and the probe. In this case the probe can also be used as a phase finder.
For IEC 61010: A selection can be made with the up scroll key as to
whether testing will be conducted under normal conditions, or with
interrupted protective conductor.
For conducting the measurement the DUT must be put into service via
key (14).

measurement.
12.2 Alternating / Direct Voltage U
AC/DC
– Max. 253 V
Direct, alternating and pulsating volt-
ages of up to 253 V can be measured
between the 2 and 3 connector jacks.
Furthermore, it is possible to switch be-
tween minimum, maximum and mo-
mentary measured value via key .
This is particularly useful in combination
with the SECULOAD test adapter for weld-
ing equipment (article number Z745V).
Attention!
!
Two procedures are to be distinguished as from firmware version 7.24:
1. DUT not connected to test socket (permanent connection)
õ Select switch position V
and then measurement U
AC/DC
.
õ Connect the measurement cables to jacks 2 and 3.
õ Scan the measuring point with the test probes.
õ Read the measured values.
õ Remove the test probes from the measuring point and pull off the
measurement cables from jacks 2 and 3.
õ Return to the Multimeter menu with ENTER.
