5. The average of the laboratory results and the Filtered Unscaled value make up one
calibration point.
6. Steps 3-5 should be repeated for additional calibration points. Ideally calibration points
should be collected to cover the entire expected Brix range of the material.
Hydro-Com software should be used to calculate the calibration coefficients and to update the
sensor with the calibration.
9.1 Good/Bad Brix Calibration
A good Brix calibration is achieved by analysing the material over the working range. A good
spread of points is necessary to provide higher accuracy.
Figure 22 shows a good calibration with all points close to the best fit curve.

Figure 23 is an example of a bad Brix calibration, this is evident as the points are not all close
to the best fit curve.
