Calibration issue or is this normal...

Is a .0014 STD DEV normal?

we are trying to measure diameters and they are reporting +.005 oversize. Could this have to do with our STD DEV being so high?

That depends on the hardware you're using - stylus, tip, length, material, module, tactile, scanner. Also, depends on if your example is in metric or inches.

Can you provide more info?

I would guess that it is metric, unless he has a 1" diameter tip.

Actually, I think that's the size of the Calibration sphere. Which made me think it would be inches. If I remember right, the calibrations results window only shows the dia of the cal sphere, and not the dia of the tip used.

I do see that the QUALTOOL_ID=25MM, which is equal to ~1" (0.9843)
