digital multimeter tutorial


Recommended Posts

Anyone know of a "Trouble Shooting Guide Using a Digital Multimeter for Dummies"? I know some of the basic stuff, but have to call a friend, who's an Ex-Marine Avionics Tech (Yea, I know, there's no such thing as an "Ex-Marine" - once a Marine, always a Marine. But that's how he refers to himself) in order to do anything other than real basic stuff. I'd like to pick up some helpful literature, if it's available.

the question can lead to a lot of vague reply...

id say first try to understand the ohm law's.

current-voltage-resistance, and the associated VERY basic formulas.




once you understand thoses bases you will understand what the multimeter shows you, thus, you will know what to look for...assuming you know vehicle's electricity basics.

other than that, what do you want to do exactly ?

Thx, guys, but having gotten "A"s in both high school and college physics I do know ohms law. And I do know how to check for continunity and volts using a multimeter. It's just the more esoteric checks that I'd like to know how and when to use. Guess I'm not making myself clear, so maybe I'll call my ex-Marine friend and see if he's got any suggestions or old manuals.

Footnote: I had not seen your post 02for2 when I posted the above. Thanks, that's what I was looking for.

...mmm, things like metering voltage drops across connections, stuff like that, right?

I think you're thinking about it backwards- try looking for electrical troubleshooting

tips and tricks- the multimeter's only a tool.

Kinda like, you wouldn't look at torque wrench sites to figure out

how to change a head gasket...
