o
NONE.
Disables the leakage measurement.
o
RMS.
Selects that the leakage check is performed on the RMS current measurement.
o
INPHS.
Selects that the leakage check is performed on the in-phase (i.e., resistive loading)
current measurement.
o
QUAD.
Selects that the leakage check is performed on the quadrature (i.e., reactive loading)
current measurement.
•
Lim
. Not available for the ACCAP type (it has limits set in different units to ACez and ACW). Allows the
user to define ranges within which each selected current measurement is considered a PASS during the
dwell period. The range can be entered in units of current or impedance, the
UNIT
key toggles the
selection. For the impedance selection the user may optionally disable the upper limit by pressing the
LIMIT
key while the upper limit is selected. For the current selection, the user may optionally disable the
lower limit by entering a zero value for it.
o
Setting a 0 minimum current limit disables the minimum limit and only applies the maximum
limit.
o
The maximum current limit (or the minimum impedance limit) is the maximum loading current
which the specific 95x model and option content can continuously supply at the configured test
voltage and frequency (see
).
o
For the ACez type the breakdown detection limit is automatically set to 2 times the maximum
RMS leakage current limit with a minimum of 1uApk.
•
C
. Only available for the ACCAP type. Allows the user to define the range within which the capacitance
measurement is considered a PASS during the dwell period.
o
The highest maximum limit which can be entered is determined by the maximum loading current
which the specific 95x model and option content can continuously supply at the configured test
voltage and frequency (see
•
DF
. Only available for the ACCAP type. Allows the user to define the range within which the dissipation
factor measurement is considered a PASS during the dwell period. The limits are applied without regard
to the polarity of the measured dissipation factor.
o
Setting a DF range of 0.0000->1.0000 will effectively ignore the dissipation factor measurement
as all dissipation factors lay within this range by definition.
•
ARC DETECT
. Not available for the ACez type and not available if DUT GROUNDED is set to YES. Allows
the user to program arc detection during this step. Both the time and current level can be independently
programmed. See
for details. Arc detection can also be disabled by setting the
leftmost (time) setting to OFF. The 95x can be configured to not fail a test step when arcing is detected by
setting the ARC setting in the CNFG
–
TEST sub-menu to DETECT ONLY.
•
DISCHARGE
. Not available for the ACez type. Allows the user to program whether the discharge period
should use the same timing as the ramp period (AS RAMP), be as fast as possible (FAST) or skipped
(NONE). If NONE is selected but the next step is not of an AC Voltage Withstand type, then the FAST
selection is used when the sequence is run. In the majority of cases, FAST should be used.
•
ON FAIL
. Allows the user to program the 95x to abort the entire sequence (ABORT SEQ) or only this step
(CONT SEQ) if this step fails any of its checks. A safety related failure or a user abort (
STOP
button) always
aborts the entire sequence.
