Dear Maureen, thank you for telling about this. When you mention
your Trifield meter's needle pushing over the limit, is the meter
set to the magnetic scale? My new Trifield meter has two magnetic
scales, one is from 0 to 100 mg, and the other one is from 0 to 3
mg. Does yours have these two magnetic ranges? My old version of the
Trifield meter only has one magnetic range, the 0 to 100 range. I
wonder what you have?
Other options the meter can be set for are "electric"
and "radio/microwave."
