Measurement menu

The contents of the measurement menu depend on the relay configuration.
If a measurement view is selected, it remains active after the time-out period. The
same is true with the manual control view. From other views, the display reverts to
idle mode at the same time as the backlight is switched off.
• If energy measurements are present, accumulated values can be reset by pressing
the [C] button for 2 s.
