So I finally fixed the Fluke 8600A DMM I got on ebay.  It appears to
use its bank of four D-size NiCads instead of an input filter
capacitor... when the cells go bad, the meter stops working, becase
the 5V DC line is more like 2V DC +3V AC.

Even though the DMM is as old as I am, Fluke has the serivce manual as
a free download from their website.  First class!

Anyway, I'm trying to get this thing into calibration as best I can. 
My only other meter is a 3.5 digit Radio Shack meter that's at least a
decade old, so it's not much good as a calibration reference.

0 V is pretty easy to obtain.   Any creative ideas on how to get other
reference voltages to calibrate this meter?

Regards,
Mark
