The fact that your using a caliper and not a mic should tell you that read lower then .0001 would be inaccurate. My digital calipers don't even read that low anyway. Either way for most robotics applications there is no need to get any closer then within a few thousands (unless we are talking about bearing bores). Not to mention that getting within +-.0001 on these small and cheap machines would be hard at the least.

Dial or Digital, whatever! Just get something that can measure accurately to within +-.001.
