On most meters, to measure current you have to move one of the leads to a different hole in the meter. Not all are this way but most. Usually there is a line drawn from the mA switch position to the appropriate spot to give you a hint where to put the lead. Also you might want to start with the highest Amp position you have to avoid blowing the fuse. If you don't have an alternate place to plug in the probe then the problem could be blown fuse. If you have the meter set up for current and then accidently try to measure voltage it will blow the fuse.
