I understand a 500v dc voltage is applied between phase / neutral and the earth return path of a class 1 appliance, and between the phase / neutral and the test probe for a class 2 appliance.
Re my query on the issue of testing a class 1 appliance with a long cord with a PT250.... an earth continuity fail result leading to a halt on the test.........and confirmation the test should have been a pass if the cord resistance had been subtracted.
Isn't this the same (insulation) test if you place the probe to an earth point on a class 1 appliance, and apply a class 2 insulation test....to overcome my issue of a halt in the class 1 test procedure.

It appears that I have made an error on purchasing the PT250, all I required was a simple PAT tester that conducted all tests without any issues...
