F1 Voltage variation as per IEC 61000-4-11
An external power source or motor driven variac is controlled
by a 0-10V control signal. The operator can select the time
per voltage level, the ramp up and ramp down of the voltage
change and the voltage levels itself.

QUICKSTART
V1 = 220 V T1 = 10 s
V2 = 120 V T2 = 1 s
V3 = 220 V T3 = 10 s
Tf = 2.0 s Tr = 2.0 s
tri = AUTO n = 00010
START CHANGE
Press START and the test routines begin to work.
Press CHANGE and the actual parameter can be changed.
F1 F2 F3 F4 F5 F6 F7
F2 Change angle after n events by ∆∆A
After n events the phase angle related to which the events
are released will change from A1 to A2 by steps of ∆A until
A2 is reached. The same parameters as under Quick Start
can be selected.
F3 Change duration after n by ∆∆td
After n events the duration of a single event will change from td1
to td2 by steps of ∆td until td2 is reached.
The same parameters as under Quick Start can be selected.
F4 Inverse mode
The inverse mode can simulate a phase control circuit, switching
power (voltage) on/off at a certain phase angle. The phase angle
is selectable in the range of 0-180°. The voltage will be switched
on/off in each half-wave. Inverse is only working in ∆∆U mode.
