Only problem.. I dont know how to use it as I have never needed to at school (10yrs ago).

If it helps the meter I have is a Jaytech QM1530
You can use the diode checker on your meter too which is what I would do so you don't have to remove the entire transistor. Its up to you though. You will need to google the transistor and find out which is the Base(B) , Collector(C), Emitter (E). The attached pic may help you to determine which is which.
Check out this video:

Using the diode checker on the meter, for a good transistor in one direction you will have continuity and the other direction you will not..(when checking from 'B' to 'E' or from 'B' to 'C'). A bad transistor will show continuity in BOTH directions.
