6.2 Class I Test (Select the Leakage current test)
Selecting Class I test while Select Switch is being pressed down initiates
Leakage current test instead of Insulation resistance test.
In case of selecting Leakage current test, metal parts other than the heating
or movable parts must be clipped with Test Lead M-7129A since the DUT
activates. Pressing the START/STOP switch during Leakage current test
stops the test immediately. To restart the test, press the START/STOP
switch again 2 sec or later than the stop of the test. Then (1) Protective
conductor resistance will be restarted.
Fig 12 indicates how to connect the devices.
