Re: [Amateur-repairs] Calibrating test equipment?

Hi David , that verifies one range on DC .. good.. but what about all the others. We have seen where people trust the meter so much than they don't believe that it is ONE input range that is "out" by a factor of 2  maybe;  not exactly a "calibration" problem, but…

Hi Tom,

Fully agree that petrology calibration costs are prohibitive for the average punter.  I use what's called a 'transfer' method to validate voltage measurements. 

 

This involves something as simple as say a lithium button battery, where you physically take that battery to a place that has say a 7.5 digit multimeter, log the reading, then compare it to your own multimeter..
