Hi Gregory,
I would think you ought to be able to modify them to 
work.  Something like a rectifying diode, resister, and capacitor 
(if needed).  You will need to recalibrate them with the resistor 
value easy to compare to a DMM.

Hi,
I'm wondering what is the best source for voltmeters and ammeters 
(such as for a control panel)? They probably come up on e-bay on 
occasion, but is there any sure source that coilers like to use or 
find work well?
I have a DC ammeter as well as a DC voltmeter from an old piece of 
equipment, but I suspect that it's probably not possible to convert 
them to AC...is it?
Thanks,
Greg
