3. Press the ISO TEST switch.
This action applies isolated line voltage between the two sides. The
Analyzer displays the isolation current that flows.
Note
The method for making connection to either side of the isolation
barrier varies with the device to be tested.
XW Warning
To avoid possible electrical shock or personal injury take
care when handling the cables. High voltage, 110 percent
of line volts, will be accessible between the two cables
when the LIFT GROUND/ISO TEST switch is in the ISO
TEST position.
Resistance
Resistance measurements between two points are made to verify the integrity
of permanently installed equipment whose ground cannot be broken to
measure the chassis leakage current. These are usually high power devices,
which can have high leakage currents and depend on the bonding of all chassis
to a common point for safety. It is recommended that these devices be powered
off for testing.
