But in any case, unless I know how to interpret those values, a bunch of meaningless 0's and 1's is not going to be a lot of use. Of course, if I could save them I would, then in the event someone ever figures out what the numbers mean, I could do a comparison. It would be nice to know if the meter is in/out of spec, but to me, I think having it put as close as possible to correct is more worthwhile, even though a metrologist who gets their meter calibrated regularly would no doubt see it different.
