verification of test equipment???

[texas bob]

hi there, new here. can anyone tell me an easy way to test my 'easytest' machine? just to make sure results are accurate. I have heard you need to test on known resistances etc but what do I use? any suggestions welcome!

there are quite a few on the market have a look here
you could use a dedicated circuit for loop and rcd tests. inbetween calibration intervals
