Buying a Digital Multimeter

[timjturner]

I'm thinking of purchasing a digital multi-meter.... I'd like to make an economic purchase. Any suggestions? I'm also not sure if I need a 46-Range or what? What does this refer to?

Thanks

One thing that would be VERY nice to have in a multimeter is a V/Hz function. Essentially a simple low pass filter with f0 = 1 Hz. That allows you to check out what motor voltage you have throughout the whole range (at least from a few Hz and up).

Or at least a filter that takes all PWM out of the signal so one can read the fundamental. I know only one meter (a current clamp with V range) that has such a filter. But no DMM.

Well, a very nice multimeter to get is a DT9205A. Its around 20 to 30 dollars. Speaking of which, does any1 out here have one? When i was repairng mine, i accidentally lost the contact positions for the selection wheel, can anyone e-mail me a pic of the selecrion wheel with the copper contacts in the correct positions?

Many years ago when I was an instrument technician, I was looking at working in Petrochem so I bought a Fluke 27. Bulking great hulk of a thing. I regret every minute I use it that I didn't buy a smaller meter. Say one thing for Fluke meters though, i've been waiting a long time for this beast to die! Stupid thing was (as mentioned in earlier post) the intrinsic safety feature isn't really much point when you can still try a test a voltage with the current tongs. When the handbrake softens on the Subaru, I won't be looking for a brick.

I just got a Nexxtech Model No. 2218202.
About $40.00 Canadian.
Auto ranging
AC
DC
Ohms/diodes/continuity(beeper)
Capacitance
Frequency
mA
Hold
Relative measurements. Take a sample measurement and subsequent measurements will be given as relative to the sample.
Illuminated Display.
Little led spotlights in the ends of the probes.
Talking. A nice voice gives you the reading, at the push of a button on the positive probe or a button on the meter.
You may also set it to talk every few seconds.
It has a good feel.
This will be my "Kicking around" meter. The meter I can afford to lose, break, have stolen or whatever.

When I win the lottery, I want a meter like Gunnars.

The cat #s referred to above really don't relate much to stupidity. They relate to the probability of a surge coming through the system sufficient to blow up a meter when it is in your hands. Great info on this subject at fluke.com.

On another note, someone asked if I knew of "Dummies Guide to Using a DMM" for beginners. Haven't found one on the internet yet, does anyone know of one?

TurboXS--

Oh, for heaven's sake! I have seen some truly memorable foul-ups from dummies with DMM's. I certainly would wish that nobody publishes a book encouraging them...
