How to use a multimeter?

I've got one and am not sure how to use it and haven't tried. Any help would be greatly appreciated.

Your question is too vague. You can use it to check voltages, measure resistance, check for continuity, and perhaps a couple of other things. What do you want to do? For voltage and resistance/continuity the red probe goes in the middle jack and the black in the bottom jack. You then ste the dial to what you want to do and turn it on using the switch below the dial. For AC voltage the dial would be set on one of the two settings top center. Use the lowest setting that is greater then the voltage you want to measure.

Most times the manual (if it has been translated well...lol) will explain all the basic functions and what they do. But as Ray said...what exactly are you trying to accomplish?

Either a cheap analog multimeter ($8-$15) or a much more expensive brand name digital meter. Cheap digitals like the one above can sometimes give false readings due to induced voltages but if you understand that can still be very useful.

Mainly checking voltage
For 120 volt circuits set to 200v. For 240 set to 750 volts. If unsure of the voltage set to 750.

Multi Meter

I was looking at something like this, just need to wait for a good sale price. Most likely more meter that I will need.

Nice gift for a master electrician whose pregnant daughter you are dating but an unpainted steel hammer will drive a nail just as good as a gold plated hammer.

Radio Shack used to print their book called "Using Your Meter" by Alvis Evans. I was looking at my copy the other day, very informative. I bet you can get a copy of it on Amazon for penny.

I have a couple of those free harbor freight jobs you have there but I don't have the guts to put those flimsy probes on line voltage!! Great battery tester though.

The Fluke 117 is likely more meter that you would ever need. I use a Fluke 7-600 which is the easiest meter I have ever used. It has been discontinued and it's replacement is the Fluke 113. For the normal user that would be the one I pick and is less money then the 117. Your sale is here!

Here is a PDF of Evans' book Using Your Meter. http://www.jumpjet.info/Pioneering-W...eful/1985a.pdf

I'll let you know how it fairs... I know harbor freight doesn't always make the best stuff but for $5 I thought I would try it out.

Can any of you smart gentlemen describe to us the proper way to use a multimeter to check voltage at circuit breakers in a live electrical panel, including the main?

The old Radio Shack book doesn't cover that one

Place one probe on the breakerscrew and the other on the neutral or ground.
