Section 4 Automatic operation - display of network parameter
The device is set to automatic operation as standard (not AUTO-INIT). Capacitor stages
are then automatically connected in or out in order to reach the target power factor. This
happens if the required reactive power is approx. 1/3 higher than the value of the
smallest capacitor step.
In automatic operation, various network parameters can be displayed by repeatedly
pressing the "ENTER” key:
