Have you guys ever watched Youtube multimeter reviews, in which they connect several multimeters in parallel, and measure the same voltage with all of them at the same time? The goal there is, having one of the meters considered as the reference/standard, to compare their measurements and calibration.
I would like to do something similar, but in my case, I would like to connect several multimeters in series and proceed to measure the same current, specifically in the microamp range, with all of them. I'd like to be able to go from a couple microamps to hundreds of microamps.
I have two questions:
1)Is this technically acceptable?
2)Is there a cheap way to do it?
I've been looking into current sources and adjustable electronic loads and couldn't find something cheap (up to $200 US dollars) that would get the job done. A diy project rather than something off-the-shelf is fine too.
ps: the multimeters aren't included in the budget, I already have a bunch of them.
