Fluke DMM's have never really given me a false value although many brands of DMM's including a number of Fluke models do sometimes freak out when looking at certain reactive loads... like some transformer windings, when trying to measure the DC resistance, which is why I also keep a trusty low cost dumb as a rock Analog Movement Multi-Meter standing by. > What wording would you suggest?

Especially during an initial from scratch default alignment.
