Insulation Tests
19
This test is used to verify that the mains supply pins and applied parts are adequately insulated from earth.
During the insulation test, a 500V DC voltage is applied between the earth pin and both the live and neutral pins
(EUT test selected) of the appliance mains supply plug or between all Applied Parts and Earth (AP test
selected). The Analyser displays the insulation resistance measured.
The Analyser can test either the EUT by itself or all the Applied Parts internally connected together. Press the
SELECT button and then press arrow keys to cycle between EUT and AP to change the mode of operation for
the test.
For Class 2 appliances, the Earth Bond lead can be used for an earth return lead for the insulation test only.
The insulation test can be operated in “UL” unlimited test duration mode. In this case the test can be terminated
by rotating the rotary switch.
