How to Use the Index Bias Correction on the Vista Follow

This "how to" describes the process to implement a bias/slope correction for an index.  Examples and 3 methods for correcting the equations are presented.

HunterLab has introduced, in its Vista product via EasyMatch Essentials software, a measurement correction algorithm that allows the user to adjust the instrument’s base performance via a Bias and Gain correction. This precisely matches reported results to assigned values for physical standards. 

The Y (adjusted Index value)=m(gain)*uncorrected Index Value + offset (bias) equation allows the end user to correct reported values using standard sets numbering just one value to many.
