I've had a cheap digital 20v voltmeter as my gauge for a couple years, but I would prefer an analog gauge. I was wondering if this 0-5v voltmeter could be used. I would program the signal output to be 0v = 10A/F and 5v = 20A/F, or something like that. Would there be any problems?

 

Full sweep volt gauge is same cost as a analog a/fr gauge.

 

No reason you can't use this as long as you remember what your calibration is (or maybe write it on a sticker).

 

One question, why?
