I bought a Fluke 3330B for under $50 -- I was stunned that it was in perfect
cal -- I just used it for an article that had a microprocessor controlled
power supply -- nice to have the Fluke so that you don't have to play around
withthe code or worry about a keyboard. It is a beast, however. I bought
a second "parts" unit in case anything goes wrong with the first one.

When you play around with these things you begin to purchase high quality
cables and connectors. I didn't know a "Seelback" from a humpback!

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.
