Hightowermark, its only my opinion, but most "regulars" seem to forget where they are.
This is a DIY Forum, not a "trade counter" with a bunch of sparks talking amongst themselves.
Often they (and me sometimes) will ask a poster how they expect to do a job with no multi meter, and here you are asking for advice on how to use one, only to be told its not a lot of use (that is the way it reads, so far)
Even with an "aproved voltage tester" you still have to test it before use, so i can not see a multimeter fuse blowing in the time it takes you to go from a known live supply to a maybe live supply.
Yes you should consider changing the meter leads if too much is exposed, but i wonder how many have insulation tape on the "ends" of their test leads.
But back to the question.
have you read the manual that came with it?, then i suggest you try something simple like a small lamp (12v) and a battery, to see what and how you use your meter
