Yes, I was a bit too quick with that link. I got the meter out and it is model DSA-540A. It does both AC and DC amps, but I see it's at the $95.- price
level. It's commonly available.
A Fluke 113 @12V DC has a precision of 2% + 3 so I think the Sperry isn't too bad. For most work, more precision isn't needed.
Yes, the good old 180 series @ 0.025% + 5 accuracy. It will be accurate to within 1/100 of a volt. But we're talking $400-$500 now.
If you look at a 0.8% +3 or so accuracy, what can you do with that which isn't possible with a 1.6% +3?
