Post:







Be mindful that not all meters are of the same
quality/toughness. Before you buy a bunch of any meters buy one or
two and try them out. Make sure they will hold up the the kind of
abuse they will receive in a teaching lab. In general a good
analog meter will cost in the range of $50 to $100 not counting
the housing. Look at Simpson or Triplet in the Allied Electronics
or Newark catalogs. It isn't surprising that cheap multimeters
are so popular.
Many of the cheaper meters tend to have their pointer pivots come
out of their bearings. Also the needles will bend when overloaded.
They just aren't built for abuse. They may work well for a
technician but will go belly up at the first abuse by an
inexperienced student. Often they can be fixed but it takes care
and a steady hand and a little time. Won't say anything about any
retailer, some sell better meters than others -just make sure what
you buy will satisfy your requirements.
