[QUOTE="NozSpark, post: 30793, member: 601"] First off you need your test standards.. Something to test:- 1) ohms readings 2) IR readings 3) Zs (you can use a nominated socket for this - preferably not RCD protected) 4) RCD operating times (you can use a plug in RCD adaptor for this plugged into the socket you use for your Zs reading) Each item you use has to have a serial number or be identified specifically The readings that you should note down are what you can test, I have a box of resistors fitted to banana sockets for my ohms and IR tests; so I note the readings that I get. When you actually get these readings, what you are after is not accuracy (a 10 ohm resistor might actually be 9.5 ohms), you are after consistency; i.e. the readings that you take from month to month should be the same (or very close). My ohms varies by +/- 0.2 ohms, IR by +/- 1 ohm, Zs by +/- 0.02ohms and RCD readings by <1ms [/QUOTE]
