Mike, thanks for the info. I thought that I had held the button down for a long enough period, but maybe not. In Fact, I was not alone at the time, a friend also tried to reset it but nothing seemed to work. I may give it another try, but this time I will try it out in the store. What's one more micrometer.
Yes Ray, it did come with the ball add on I had to pay extra for the one on my Starrett.
