When a stage is switched out again, this is done immediately. Before this stage can
be switched in again, it is necessary to wait until the capacitor‘s set discharge time
has elapsed. A countdown of the remaining discharge time is displayed in the Sta-
tus column. Not until this time has elapsed can the stage be switched in again. If it
is attempted to switch in the stage before the countdown is finished, the message
‘Not possible’ is displayed. (The stage is then not switched in automatically after the
discharge time has elapsed.)
Pressing the key displays the momentary values of
cosφ, P and Q.
