3. OPERATING PROCEDURES:
If the instruments defaults are acceptable then be sure to connect the appropriate
test leads to the device under test (DUT) or test fixture. Be sure to connect the
safety ground (on the rear panel) to a suitable known good ground before
energizing this instrument. First, connect the return lead to the test fixture or
DUT, then connect the high voltage lead.
Check your connections to be sure they are making good contact. Clear the area
of any debris that may create a hazardous situation and ask any unnecessary
personnel to leave the area.
DO NOT TOUCH THE DEVICE UNDER TEST ONCE
THE TEST HAS BEEN STARTED.
Please follow the setup procedures to set the parameters. The display will show
the Dwell or Delay Timer value, the Test Voltage value, and the High Limit
Setting and memory location.

3.1. Ground Continuity Check
If you are performing a Ground Continuity Check, the Ground Continuity must be
set to the “ON (Enabled)” position. The ground check cable has to be connected
properly to the chassis of the DUT and the green indicator on the TEST switch
should be illuminated before activating the Test switch. Otherwise, the instrument
will signal a
continuity failure when the test switch is activated. Please refer to
page 35 for the proper test connections using the adapter box, to test items
terminated in a three-prong plug.
The display will show:
CONT. MX XXX.Xs
- .- - KVAC - -.- - mA
If you are not performing a Ground Continuity Check, the Ground Continuity must
be set to the “OFF” (Disabled) position. It is not necessary to connect the “Cont.
Check” cable since this test will not be performed if the circuit is disabled. The
instrument will proceed with the Hipot Test when the “Test” switch is activated.
