2. C onnect the black cable with the clamp with black insulation to the
CHASSIS connector and the black cable with the clamp with red
insulation to the DUAL connector.
3. Toggle the LIFT GROUND/ISO TEST switch to ISO TEST to apply
isolated line voltage between the two sides. The meter displays the
isolation current that flows.
Note
The actual method for making connection to either side of the
isolation barrier varies with the device to be tested; therefore, full
details are not provided.
W X Warning
To avoid possible electric shock, burning of the skin, 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 that
can have high leakage currents and depend on the bonding of all chassis to a
common point for safety.
To measure resistance between two points, follow the steps below:
1. Disconnect any device attached to the Analyzer instrument receptacle.
2. Turn off any electrical devices to be tested.
3. Connect two black cables with clamps with black insulation to the
CHASSIS and DUAL connectors, and clip onto the two points to be
measured.
4. Set the FUNCTION switch to Ω - RESISTANCE, and the display will
show the resistance between the two points.
