Mine has 4 beats/sec by ear. I practice with 1001, 1002, 1003, 1004 ... until I believe I have the 1 second rhythm. Then I count the beats 1,2,3,4,1,2,3,4...to determine if they are the same. It would probably be easier to use a stop watch and count 20 beats for example but I would have to get one out.
Thanks Ben, I thought they would be 18,000 as well but I have dug another out from the bank safe and it keeps perfect time. So I put it on my B300 machine and it will not pick-up on auto, the first one I was talking about also will not pick up on auto either. When I change the beat frequency to manual @ 18,000 it still will not pick up amplitude or beat error, but if set @ 16,200 manually they both immediately registers all measurements and they time in perfectly, I'm just wondering if my timing machine is on the blink?
