You probably blew the fuse on your meter by not paying attention to what you were 
connecting it to.  In particular, if you don't set the dial to the 
appropriate function and scale BEFORE you make the connection, you run the 
risk of putting too much current through the meter's indicator needle 
circuit.  The latter is protected by a fuse.  So open it up and check it
out.  You can check the fuse (if it is opaque) with someone else's Ohm 
meter.  (It conducts if not burned out!)  There are probably two spare fuses 
in your kit.  (Use the right one, not one of the wrong ones -- there are two 
different sizes.)  Also, you can in the future get more fuses from the Help 
Lab parts closet (which has 24/7 access with a South Campus Master.)
