Digital Multimeter's Need to learn how to use?
Anyone have a link to good info on using a Digital Multimeter for a DMM newbie? Indepth info would be really useful, as I am very new to all this. Basically wanting to troubleshoot automotive wiring issues, but not sure on how to use this new meter.
Try this:

Very nicely done with lots of illustrations.
On a personal note, here's a few tips:
1) Notice which jacks the test leads need to be plugged into. Usually you need to plug them into different jacks for different kinds of measurements.
2) If the meter has a knob for selecting the type of measurement, set it the right kind of measurement before connecting the leads. That is, don't have the switch on off, hook up the leads, and then twist the knob through volts and amps to get to ohms (or whatever). Note that some meters have selectors that make this impossible.
3) Measure voltage and and ohms by putting probes "across" something (like a battery or a wire). Measure amps by breaking the circuit and putting the meter "in" the circuit. When measuring amps the meter looks like a short circuit so do NOT connect the probes across something in amp (current) mode.
Good luck!
