The meter worked fine when I set it up,but after I sat down and adjusted the tension it stopped working correctly. It powers on when I push the mode button, and the pulse part still works, but none of the functions associated with it being attached to the pedal seem to work. It isn't measuring time/dist/calories/speed, and it doesn't come on automatically when pedal. I suspect a wire came loose, but I'm leery of taking it apart when I don't know exactly what I'm looking for. Would appreciate any advice.
