[QUOTE="Geoff1946, post: 533540, member: 28452"] I don't know the tester you have but I would be looking to satisfy myself that there was good earth continuity through the mains plug to the machine frame and that the insulation is good. Can your tester do that? Potential problem is that there is surely a contactor incorporated which prevents you switching on. Some testers allow a leakage test whilst operating. The comment on "lead compensation" is of concern. Is it very long or thin? It shouldn't give more than about 0.25 ohm at most ? What's it showing? That could be justification for a fail especially in a workshop environment, and then your job is done. Otherwise it sounds like a contender for maintenance department to check. Doing that task with limited electrical expertise you should err on the side of safety. As with all PAT work by far the most important part is a thorough visual inspection. [/QUOTE]
