Leakage Current
Follow these steps to verify leakage current functions.
1. Passive leakage current test:
a. Select Calibration > Leakage current .
b. Connect the 5522A current output terminals to the HI, LO input terminals of the
Product. Select the ac current function on the 5522A and set the frequency to 55 Hz.
c. Set the first test current on the 5522A from Table 26 .
d. Select IC1 Leakage current 0.3mA and push
O
. The Product ammeter starts to
measure.
e. Switch the 5522A output on.
f. Compare the measurement on the Product with the limits in
Table 26 .
g. Do the tests for next two ranges, IC2 3 mA and IC3 30 mA .
2. OPEN substitute leakage current test:
a. Connect the 5522A current output terminals to the HI, LO input terminals on the
Product. Select the dc voltage function in on the 5522A and set the output value to
45 V.
b. Select Leakage current > Substitute Open mode.
c. Switch the output terminals on the Product and the 5522A.
d. Compare the test voltage on the Product with the set voltage on the 5522A.
3. Active leakage current test:
a. Connect the standard multimeter current input terminals to the HI, LO terminals on the
Product. Select the ac current function on the multimeter.
b. Select Leakage current , item Active on the Product. Set the output current to 20 mA
and push
O
on the Product.
c. Compare the standard multimeter reading with the set output current value. The value
reads within 19.94 mA to 20.06 mA.
