4/Calibration and Adjustments
. Normal Polarity Leakage Current Test
. Place the polarity switch of the Leakage Current
Tester in the "Normal" position. (This is in the
grounded mode.)
. Switch "On" the power of the device under test.
. Measure the voltage on the DMM
in millivolts.
The millivolt reading is directly related to leakage
current in microamps
(i.e., 100 mv is equivalent
to a leakage current of 100 microamps).
. Push the "Ground Disconnect"
switch to meas-
ure the ungrounded leakage current.
. Switch the power switch of the device under test
"Off" and then repeat steps 2c and 2d.
. Reverse Polarity Leakage Current Test
. Place the polarity switch on the Leakage Current
Tester in the
"Reverse"
position.
(This is the
grounded mode.)
. Switch "On" the power of the device under test.
. Measure the voltage on the DMM
in millivolts.
The millivolt reading is directly related to leakage
current in microamps,
(i.e., 100 mv is equivalent
to a leakage current of 100 microamps).
. Push the "Ground Disconnect" switch to meas-
ure the ungrounded leakage current.
. Switch the power switch of the device under test
"Off" and then repeat steps 2c and 2d.
