Standard Deviation

[Darrollh]

Good afternoon,
I am have an issue with one of my probes. I’m getting a SD of .001. Not sure what’s why. Just thinking out loud.

Try swapping out the extension(s)/tip(s) and try again. You can narrow down if it's due to a module going bad or the extension/tip that is going bad. Also, make sure you don't have too long/heavy of a tip for the particular module you are using! You could also add a few more points to the calibration routine. I've also lowered my STD by a few tenths from changing from 13 hits to 17 hits for calibration.

Loose probe, dirt on probe, chipped probe,buildup on probe, bad module, dirty calibration sphere.....

Thanks guys. I’m using a smart standard force module. I’ve change the stylus and got the same results. I’m going try increasing the hits and doing a thorough cleaning. Thanks you all!!
