Understanding Calibration Results on CMM Reports

L

lee01

I’m having a lot of trouble of late and one of the problem is understanding CMM calibration reports with especial consideration to the following reading:

E= 3.5 + L / 150? I understand this is the measurement of both repeatability and accuracy using a length, but can someone please go through it with me as you would type it into the calculator to gain a simple micron reading please!

Many thanks for your assistance!

lee01,

There doesn't seem to be much help here. I am going to move a copy of this to the 17025 thread. That thread also addresses MSA and they may be able to help.
