3.4.3. CONFIGURING THE MEASUREMENT
Before starting the measurement, you can configure it by modifying the parameters displayed:
To choose the nominal test voltage UN: 50, 100, 250, 500 or 1000 V.
To activate the alarm.
To deactivate the alarm.
k Ω 0500.0
MΩ
To set the alarm threshold (see §3.17). As default, the threshold is set to
R (kW) = UN / 1 mA.
Before the measurement: to display the measurements already recorded.
During or after the measurement: to record it.
The direction of the arrow indicates whether you can make a reading (arrow pointing out) or a recording (arrow
