Cal-Card............................

[Baker1988]

I was wondering if any on know if any of the wholesalers sold cal-cards over the counter? I know i can buy on online but now it wont wont get here till next week and could really use one to just check my tester it is calibrated but just wanted to check.

They are poop.

You'd be better off with something like the Kewtech FC2000

have a cal card and find its all down to pressure to get consistant contact to get consistent results.
better of buying a couple of resistors and clipping them on to the croc leads...
I have the kewtech fast check and find its worth its money... it came as part of a packaged deal. If i recall correctly they cost around £90 on there own. if the results are out on the fast check its 99.9% likely to be a zeroing/nulling issue with the leads and contact resistance. find its always spot on if i dont null leads first.

Yeah might get one of the kewtech ones they seem pretty good

I got a calcard from moons ago that still tallies up fine with my mft. Generally find it pretty accurate. On IR my meter might read 49.8Mohms for the 50Mohm value.

i made my own with an adaptable box, some 4mm nuts, bolts washers, and a selection of resistors from 0.1 ohms to 10 meg.

Hi mate
CEF and Neweys do them in branch but it depends on area and their stock obviously. If thats any help

Nice tight-tolerance resistors I hope Tel
