to the I or ON position. The tester will
perform a self-diagnostic test.If the
Volts/Amps switch is set to Volts, the meter
will swing.
2. Set the Duration control to maximum
counterclockwise position using the
supplied tool.
3. Confirm that the volts/amps switch on the
front panel is set to Volts.
4. Plug the split end plug of the 10 AWG Test
return lead into the "Chassis" Receptacle of
the Tester.
5. Plug the supplied 10 AWG Test Power Cord
or non-detachable EUT power cord into the
"Device" Receptacle of the Tester.
6. Connect the alligator clip end of the Test
Lead to the chassis of the equipment to be
tested.
7. Push the test button. The test will continue
only as long as the test button is pressed. A
test time of 5 seconds is recommended.
8. The voltage drop of the grounding circuit
alone, not counting the resistance of the test
leads, will be shown on the front panel
meter.
9. To test for longer times, we recommend the
method above be used first to validate test
setup. After the test setup is reliable, set the
Duration control on the rear panel to the
desired test duration. The test will continue
for the desired time after the TEST button is
pressed.
Test results (Production Line Use)
By noting the voltage readings, dc resistance of
the grounding path of the EUT can be easily
determined. In the vast majority of cases, the
acceptable resistance of a grounding circuit,
neglecting the resistance of the power supply
cord, is 0.1
Ω
. If this is the case, and a current of
25 amps was set, a voltage result of less than 2.5
volts would be acceptable.
