How do you ensure its within the mV rated range? Fluid sensors needs a pretty sharp resolution to function to specs, no? Was under the impression only a computer was geared for this sort of accuracy. Mind you if one have a industrial grade multi-meter then it might be doable. Really dunno... excuse my ignorance on the subject, never done it. Interesting stuff
Warning: requires 10 mega-ohms independence multi-meter on Porsche cars (and Prius). To prevent drawing too much current and damaging the other end, something like that
Porsche are complex things! Love it tough...
