RUN SINGLE
RUN SINGLE command will run the test once. The Variation test is defined by the REDUCE TO,
FALL TIME, HOLD TIME and RISE TIME parameters. These parameters must be set before
starting the test. The following is a description of these
REDUCE
TO: The lowest voltage level as a percentage of the nominal voltage. Thus, 0% is 0
Volts. 100% is full nominal voltage.
FALL TIME: The time in seconds it will take the output to reach the REDUCE TO voltage.
Values must be entered in
voltage drops instead of voltage sweeps to support Edition 2.0 of the test
standard. This requires firmware 2.38 or higher however.
HOLD TIME: The time in seconds the output will hold at the REDUCE TO volt
must be entered in seconds.
RISE TIME: The time in seconds the output will reach the NOMINAL voltage from the
REDUCE TO voltage. Values must be entered in seconds.
The timing of voltage variations is different between editions 1.0 and 2.0 of
test standard. While the original standard used voltage ramps on both sides of the variation test
level, the Edition 2.0 standard calls out an abrupt drop to the test level, followed by a voltage
ramp back to the nominal voltage. Thus, f

Furthermore, where under Edition 1.0 rise and fall times were specified in seconds, they are
specified in number of cycles in Edition 2.0. This is an effort to normalize both 50 Hz and 60 Hz
voltage variations.
