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..
