I've used several DMMs, own three, and would recommend the Fluke
75's as a good general purpose DMM. There's a jumper underneath the
display, marked as a 0 Ohm resistor (single black color band), which
if soldered to the left makes the DMM a 75 model, and if soldered to
the right makes the DMM a 77 model, about $40 pricier.
A few of my friends have 75's whose jumpers somehow :->
got switched around, and they find the touch-hold feature quite useful.
For low-precision work (how often do you need better than
a couple of percent accuracy, anyhow?) Radio Shack has meters with
good mix of features for $30 or so. Beckman and Metex brands are
deluxe low-priced models, and a friend of mine has a $39 Beckman
model that measures capacitors in addition to more ordinary
features. Consider the low-priced models before you decide
that you need a name brand.
The only fault of many inexpensive meters is their INATTENTION
TO FAULT CONDITIONS. A Fluke meter dialed to "Amps" and plugged into
a wall socket will burn up a fuse. A low-priced clone meter will
sometimes burn up. I use a couple of cheapos, but I'm careful
with them; only my best meter can be safely loaned out ('cuz it can survive
even MY friends...).
Jameco (415) 592-8097
has Metex M3650 multimeter with frequency and capacitance
measurement, transistor Hfe, audible $59.95
Kingdom auto-ranging shirt pocket DMM $27.95
and I assume other mail order suppliers have similar deals.
I am known for my brilliance, John Whitmore
by those who do not know me well.
