Can anybody explain the tests to be carried out and how this would be done prior to working on an appliance, eg earth continuity, correct polarity with appliance ON and OFF. testing correct voltage etc.
I have placed the probes of a multimeter on the live and neutral pins at the plug of an hairdryer but the reading stays at 1. Should I not get a resistance. It was set at 200 OHMS.
Dont worrry Im not tampering, its part of a course Im doing but curious to know more.
Thank you.
