1: Bias lets us know what the variation is from the targeted measurement.

Say a 0-6" height gage is measured to a .500 gage block and measures .001 off of the target. That is your bias and needs to be taken into account when measurements are taken on the instrument.

Same height gage:

At 1" the gage has a bias of .001
At 2" the gage has a bias of .005
At 4" the gage has a bias of .002

This equals linearity. The height gage may be within acceptable standards to measure within .001 at the 1" level and .005 at the 2" level.

IMHO
