HOLD TIME:
The time in seconds the output will hold at the REDUCE TO voltage.
RISE TIME:
The time in seconds the output will reach the NOMINAL voltage from the
REDUCE TO voltage
The timing of voltage variations is different between editions 1.0 and 2.0 of the IEC 61000-4-11
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, for Edition 2.0, the fall time must be set to 0.000
volt e riation
and Figure 9-18 for an illustration of how these parameters affect the V
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.
FALL TIME:
The time in seconds it will take the outpu
seconds. This requires firmware revision 0.31 or higher. Older firmware revision will not accept
0.000 sec for fall time. The shortest allowable fall time for older revision firmware is 0.02 sec.
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
