Ed, if the count goes up as you move the cross slide to the back, (ie as the dia gets smaller, then the scale needs to be reversed, electronically in the readout. The manual should tell you how. If thus is the case it must not work for OD turning either, OD ID is the same. A quick fix is enter your measured dia as a negative number.
Free advice is worth exactly what you payed for it.
