[ARC5] Meter Calibration

[Robert Eleazer]

I have quite a collection of multimeters and voltmeters. Some PSM-6's. Some PSM-45's. A couple of Me-297's. A USM-33.   A USM-34.   A Simpson 260 in a super-nice rolltop carry case. An NLI TouchTest 20 with real red glowing LEDs. A brand spanking new HP Model 410B. 

And I don't trust any of them, at least not very much.  I quit using those super cheap chicom digital meters because each one gave me a different reading.  But collectively all of the others have the same problem.

Anyone know how you can go about calibrating at least the voltage readings on these fine equipments?  That is, using stone knives and bearskins, not a million dollar test set.

Thanks,

Wayne
