4.2.7 WAVEFORMS Menu

Figure 4-17: WAVEFORMS Menu

The WAVEFORMS menu allows selection of the wave shape for each phase individually or all
phases at once. In three-phase mode, the mode is determined by the phase coupling.

The selected phase is shown in the top right corner of the display (øA, øB or øC). The selected
wave shape will be applied to that phase. If all phases are selected (phase coupling), the
selected waveform will apply to all three phases.

The following fields are available in the WAVEFORMS menu:

CLIP LEVEL

This parameter determines the amount of total harmonic
distortion of the built-in CLIPPED sine wave waveform. The
range is 0 % through 20 % THD.

Note that changing the distortion level of the CLIPPED sine
wave while the CLIPPED sine wave is used on the output of
one or more phases, forces the output of the AC Source to be
dropped momentarily. To avoid this, make sure none of the
phases is using the CLIPPED sine wave function when
changing the clip level.

GROUP

The group field displays the currently selected waveform group.
There are four groups of 50 user-defined waveforms each for a
total of 200 waveforms. Only one group can be active at a time
however. This field only displays the selected waveform group.
It cannot be used to change the actual group selected. Group
selection must occur at power up and is done from the INITIAL
SETUP 3 screen. See section 4.2.11.3 for details.

MODE

The mode field determines the operation mode of the
WAVEFORMS display screen. Available options for this field
are:

PROG:

This mode is used to change the programmed

wave shape function on the selected phase. This is also the
default mode of operation.

VIEW (T):

This mode can be used to display any of the

available user defined waveforms in a time domain display.
Previewing a waveform can be useful if you are unsure about
the nature of the waveform that was stored.
