The external voltage source is connected to one end of the material sample, with its common terminal grounded,
and the 95x RETURN terminal is connected to the other end of the material sample.
If the voltage being used is within the measurement capability of the 95x, then the output of the external voltage
source could also be connected to the HV terminal of the 95x, in which case the 95x display would also show the
actual applied voltage to the material sample.
A single step is used as follows
–
Seq 1 Step 1 DCI
DC leakage required, so use DCI
TIME: user sec
Use manual timing, press the START button when finished
Delay: 0.00sec
Already connected, so no delay needed
Lim: 0n-5.000mA
Set wide limit, the user will manually check the results
ARC DETECT:OFF
Not required so disabled
ON FAIL: ABORT SEQ
SPECIFICATIONS
Specifications are valid at the 95x terminals for 1 year at ambient temperatures within ±5C of calibration
temperature (add 5% of accuracy specification per C outside of this). All specifications are relative to the
calibration standards used. Add ½ digit to all accuracies for displayed results (results available with enhanced
resolution from interfaces).
