Semiautomatic Measurement Between Measuring Points
Fast, semiautomatic measurement is possible in all rotary switch
positions for resistance measurement. However, measuring point
selection is only relevant for documentation in the device’s internal
database.
Fast Pole Switching
Fast and convenient switching amongst all of the specified mea-
suring points without opening the parameter settings submenu is
possible after each measurement by pressing the save button on
the instrument twice.
Start Measurement
Continuous Measurement via the CONTIN Key
Note
The instrument’s batteries are exposed to excessive
stress during insulation resistance measurement. Stop
continuous measurement with “constant test voltage”
as
soon as the display has settled in.

Measurement Results
6.1 Discharging the Device Under Test
Attention!
!
If measurement is performed at a capacitive object such
as a long cable, it becomes charged with up to approx.
600 V!
Touching such objects is life endangering!
When a resistance measurement has been performed on a
capacitive object it is automatically discharged by the instrument
after measurement has been completed. Contact with the device
under test must be maintained to this end. The falling voltage
value can be observed at the U display.
Do not disconnect the DUT until less than 10 V is displayed for U!
