Romer probe

You need to be careful if it is a tight tolerance hole - any edge break or deburr will add depth to the probe and give you a larger reading, and if the hole is not deburred, a burr can cause the same issue the opposite direction. Under "measure circle" you have the option of 3 point or single point. Make sure your workplane is the surface the hole enters or it will error out.

Go to the View drop down> then Other Windows> Then chose Quick Start
Within Quick Start, chose to measure a circle. At the stop of the Quick Start window, you'll see a box to check called "Single Point Select". Check this. now, you'll only be prompted to take one hit within the circle. Your probes should rest in the hole/bore you're measuring when you accept the hit.
