[QUOTE="boltonsparky, post: 505261, member: 4678"] Just done my calcard check on my meter this afternoon on one of your cards which is a great little idea. The RCD ma setting on your machine. Mine starts at 10ma then 30, 100, 300, 500, 1000. It's a megger 1552 (yes an older MFT) not sure how that compares to the newer ones. Time settings seem logical to me but I find a lot of RCDs seem to trip around the 10ms area so might be worth having that option in there too. Ze Might be worth, if it's possible, using the most common 60898 B type values maybe. Although if it's to check ongoing calibration the values don't really matter I guess as you're checking against a known value and looking for change. Depending on price point it'd be good to have something with a Ze test function as in the past this has been the measurement that has wondered away from calibration on my previous meters. Back to RCDs with the newer types now available covering DC will your contraption include a DC test for RCDs too? [/QUOTE]
