3.2.
Initiating a Test
To initiate a test, press the TEST switch on the front panel. The red High Voltage
Arrow indicator will flash and the display will immediately show:
Ramp MX XXX.Xs
X.XXKVAC XX.XxmA
or
Dwell MX XXX.Xs
X.XXKVAC XX.XxmA
The instrument will continue to output the desired voltage for the duration of the
selected dwell time.
3.3.
Short Circuit
If there is a short circuit in the DUT during the test, the red indicator light will
illuminate on the RESET switch and an alarm will sound. The display will show:
HI-LMT MX XXX.Xs
X.XXKVAC OFL mA
3.4.
Flash Over
If a flash over occurs in the DUT during the test, which results in an OFL
condition due to the current exceeding the maximum metering range, Breakdown
will be indicated as follows. The red indicator light will illuminate on the RESET
switch and an alarm will sound. The display will show:
HI-LMT MX XXX.Xs
X.XXKVAC OFL mA
3.5.
Leakage Current Exceeding the Metering Range
If the leakage current exceeds the metering range and neither a short circuit nor
flash over occurred, the red indicator light will illuminate on the RESET switch
and an alarm will sound. The display will show:
HI-LMT MX XXX.Xs
X.XXKVAC OFL mA
3.6.
High Limit
If the leakage current exceeds the high limit setting, but does not exceed the
metering range, the red indicator light will illuminate on the RESET switch and an
alarm will sound. The display will show:
HI-LMT MX XXX.Xs
X.XXKVAC XX.XxmA
