Axial Displacement Probe Calibration

A

Thread Starter

ahm2

we make calibration for eddy current axial displacement. we get voltage/displacement
mm---VDC
0--1.16
0.5--1.16
1---3.13
1.5---5.24
2---7.41
2.5---9.57
3---11.74
3.5---13.99
4---16.15

the tolerance
the maximum positive linearity error 1.50%
the maximum negative linearity error -1.50%

we have a calibration sheet from manufacture and the linearity diagram. my question is how get the ideal values from diagram to calculate the error?
