Gram Gauge, #'s correction

[Farrell]

Forgive me for sticking my nose in here BUT, these guages clearly appear to
be for static resistance measurement. They will not work for measuring down
and up weight - or at least they will not work in a meaningful way. Also,
the accuracy of the first two guages referenced is 0.5% of the total scale.
0.5% of 5,000 grams is 25 grams. I think we need to be more accurate than
that. The other guage may actually be kinda nice for measuring flange
resistance, (the 0 to 10 gram jobbydo), but again, not for measuring down
and up key weight. Especially so that one can compare your results with that
of most every other technician that is advanced enough to own a set of
accurate gram weights. (Don't mean to sound nasty, but I think it really is
true.) :-) All meant in a positive manner! Why do I feel like I'm gonna get
flamed? Oh, well.  ;-)
