If the green Full Voltage LED lights and the test continues, the leakage current was
below the amount set by the rear panel adjustment.
Sporadic Leakage Current Failures
If the red Excess Leakage LED lights, the buzzer sounds, and the test is terminated, the
leakage current delivered to the equipment being tested was over the amount set by the rear panel
adjustment. If other equipment of the same type routinely passes this test, there may be a
problem with the primary circuit of the example being tested. The unit should be checked and
reworked if necessary.
High Voltage Dielectric Withstand Test
This test checks for insulation system breakdowns between the primary and ground
circuits. The HT-2800P uses a separate high-frequency transformer circuit to check for and
detect arc breakdowns.
The dielectric withstand test is conducted by shorting the line and neutral conductors of
the power supply cord and applying high voltage between them and the exposed dead metal of
the chassis of the equipment being tested. The duration of the test is controlled by the test time
control on the back panel. The test time is counted from the time the
Full Voltage LED is lit to
the completion of the test.
If the green Hipot Pass LED lights, the test cycle has been successfully completed. The
equipment under test is in accordance with the preset test parameters. The HT-2800P is ready to
test the next piece of equipment.
