One of my favorite gadgets is the Datel DVC 8500 voltage calibrator.
Small, fairly stable, +/- 19999 mV via thumbwheel switches, plus
trimming. They pop up on eBay aperiodically (one currently listed,
going for $31, and recently calibrated -- a deal. Item 3814748987).

I am looking for an accurate voltage source around 12 volts to use to
check calibration on digital voltmeters. .01% would be nice.

Does anyone know about the 3 terminal voltage reference chips
available? Would they do the job?

Thanks for any help.
