27. Q Hi-Lmt (PROGRAM Mode only) - gives the operator the flexibility to
program a maximum reactive power threshold or floor level. When this level is
reached a failure will occur. Q Hi-Lmt is only selectable when the source is
configured for AC output.
28. Q Lo-Lmt (PROGRAM Mode only) - gives the operator the flexibility to
program a minimum reactive power threshold or floor level. If a minimum
reactive power level is not reached a failure will occur. Q Lo-Lmt is only
selectable when the source is configured for AC output.
29. Trans-Volt - gives the operator the flexibility to program a surge or drop in
the voltage output. Whether the voltage is a surge or a drop depends on the
voltage that is programmed for this parameter. For example if the output
voltage is programmed at 120 volts and the operator programs in a Trans-Volt
of 150 volts this would be a surge of 30 volts. The opposite holds true; if the
Trans-Volt is programmed at 90 volts this would be a drop of 30 volts. Trans-
Volt is only selectable when the source is configured for AC output.
30. Trans-Site - gives the operator the flexibility to program the specific point
in the sine wave to initialize the surge or the drop voltage. For example since
a 60 Hz sine wave occurs 60 times per second, if the operator programs the
Trans-Site for 8 milliseconds the surge or the drop voltage will occur at the
halfway point (8 millisecond) of the sine wave or at the 180º point. Trans-Site
is only selectable when the source is configured for AC output.
31. Trans-Time - gives the operator the flexibility to program the overall time
duration of the surge or drop voltage. For example if the Trans-Site is 8
milliseconds; the output voltage is 120 volts; the surge voltage is 150 volts;
and the Trans-Time is 20 milliseconds when the sine wave reaches the 8
millisecond point (180º) the voltage will surge to 150 volts. This surge will hold
for 20 milliseconds before the voltage output returns to 120 volts. Trans-Time
is only selectable when the source is configured for AC output.
32. Trans-Cycle - gives the operator the flexibility to program whether the
transient voltage will occur continuously for each size wave of the test routine.
The operator has the choice of selecting 0 or 1-9999. Trans-Cycle is only
selectable when the source is configured for AC output.
33. Phase Set (Option 08 only) - gives the operator the flexibility to adjust
the hi- and lo-limits for all phases during 1Φ3W and 3Φ4W modes. Selecting
L1-N will allow the operator to set the limits for the instrument providing L1-N
output voltage. Selecting L2-N will allow the operator to set the limits for the
instrument providing the L2-N output voltage. Selecting Phase A, B, C will
