    Many multimeters have a battery in them to power the display.· Do you have a fresh battery in the Metex M3850?· Is it inserted correctly?

    Also check you leads/probes.· is the wire firmly connected to the jack and to the probe?

    When I got my first MM I made the mistake of trying to measure the current of a circuit by placing it in parallel with the ciurcuit instead of serial. This low impedance path made much more current flow through the MM than it was designed for, and a fuse inside the MM was blown, openning up the MM and replacing the fuse fixed the problem.

    LOL, I sent my $250 dollar MM to hell the same way. I took it one step further though. Swapped the low range(1A) and high range(10A) fuses because I was in a pinch, forgot about it, made the same mistake a week later.....Poof! Everything still worked except the current portion! Now I keep a box of fuses in the case of my new meter.
