During the AC Withstand Voltage test Ramp-up, the display will show the values being
updated in real time as follows:
ACW Ramp-up XXX.X s
MXX-X X.XX KV XX.XX mA
During the AC Withstand Voltage test dwell cycle, the display will show the values being
updated in real time as follows:
ACW Dwell XXX.X s
MXX-X X.XX KV XX.XX mA
If the ramp time is very short and the program has not read the meter readings, the display will
show:
ACW Dwell XXX.X s
MXX-X - . - - KV - - . - - mA
At the end of the dwell cycle when the voltage begins to ramp down, the display will show the
values being updated in real time as follows:
ACW Ramp-down XXX.X s
MXX-X X.XX KV XX.XX mA
NOTE: In order to view the ACW values measured during the dwell cycle the review key
must be pressed.
DC Ramp Down
The DC ramp down feature allows the DC voltage applied to the DUT (or stored in the DUT),
to be reduced linearly over a specified period at the end of a hipot test.
There are three set up screens associated with this feature that will allow control of Ramp-Up,
Dwell, and Ramp-Down.
The setup screens will appear as follows:
Ramp Up = XXX.X s
Range : 0.4 - 999.9
Use the “Numeric” keys to enter the Ramp Up time setting, then press the “ENTER” key. The
program will store the Ramp Up Time setting and advance to the Dwell Time parameter
automatically. The unit is “second” and 0.1 second per step.
