[ARC5] Meter Calibration

[Geoff]

I wonder if that DMM will work with a Fluke HV probe?  Is the input 
impedance listed?

Those cheap meters are in every vehicles glove compartment, garage, toolbox, 
etc. Fine for the basics and Ive fried a few also (-; I bought a case lot of 
20 for something like $50 at a local fleamarket several years ago. Tossed 
the junk batteries and leave batteries out of the unused ones until needed.

I bought this relatively inexpensive DMM from Harbor Freight:

http://www.harborfreight.com/5-in-1-digital-multimeter-98674.html


"Just in case" I were to have problems with my Fluke. The meter reads within 
less than 1% of what I read on my considerably more expensive Fluke!

I did get it "on sale" for like $34.95 a few months ago.

The quality of things bought at Harbor Freight range from absolutely junk to 
pretty darn good! One has to look at the item and make a determination of 
the quality. Fortunately, there is a Harbor Freight outlet about 5-miles 
from my house which does allow me to look at the item before purchasing.

I also have several of the Harbor Freight "red" DMM units that are often on 
sale for as little as $1.99 each at the local store. For "quick" 
measurements the accuracy is fairly good. Not as good as my Fluke, but, good 
enough to see if things are working properly. Besides, if I happen to blow 
one up (haven't done so this far, but there is always a possibility), at 
$1.99 each, I haven't lost any real money.

I generally keep one of these "red" DMMs in each tool box, in the glove 
compartment of my car, etc.
