Representation on the display
A stroke (bar) above the phase designation (a, b, c) indicates that the displayed value is a
sliding window demand value.
Figure 3-2
Maximum sliding window demand of the active power
You can display the sliding window demand with function key F1: First select the measured
variable. Then scroll to the demand display with F1.
Parameterization of the averaging time
The averaging time can be parameterized on the display or via the communication interface.
The following can be set: 3, 5, 10, 30, 60, 300, 600, 900 seconds.

Other properties of measured variable representation
Zero point suppression level
The zero point suppression level can be set via the interface in 1% steps in the range from
0% to 10% of the primary rated value of the external current transformer (default value
0.0%). Currents within this range are indicated on the display with "0" (zero).
Current direction
The current direction can be changed on the device or via the interface individually for each
phase. It is not necessary to change the terminal connections of the current transformers in
the event of connection errors.
