The measured value is displayed in the history memory.
Displaying the current measured values
The standard display shows the currently measured value for R
other measured values. After 5 min at the latest the display switches back to the standard display.
ADVICE
The pulse symbol indicates a currently measured value. If this symbol does not appear, the
measurement is still ongoing and the latest valid measured value will be displayed. The symbols "˂"
or "˃" will be displayed additionally to the measured value when a response value has been reached
or violated, or the measured value is below or above the measuring range.

Setting the response values (AL)

4.4.1

Setting the response values for monitoring the insulation resistance

How to proceed
1. Open menu "AL".
2. Select parameter "R1" for prewarning or
parameter "R2" for alarm.
3. Set value and confirm with Enter.
