1/4 sine wave that starts at 6V and rises to 10V over 5 ms (1/4 of 20ms period established
by 50Hz frequency). The waveform shown in Figure 3-11 has now been saved. Note that by
careful calculation of period and start/stop angle, accurate waveform simulations can be
attained.

COPYING A WAVEFORM
After observing the precautions of PAR. 3.3.9.1, press
the Saved Waveforms screen (Figure 3-9). Highlight one of the stored waveforms, then press
$
. Then highlight a waveform location designated Empty and press
the change and exit. The copied waveform may then be modified and saved with a new name if
desired (see PAR. 3.3.9.7).

RESET
CAUTION: PRESSING RESET WILL CAUSE VOLTAGE TRANSIENTS TO APPEAR AT
Pressing RESET causes the power supply to execute a complete power on sequence to reset
the power supply to the power up settings (see PAR. 3.3.7).
