Why there are variations in the results, when analyzing water (instead of milk)

 Example from measurements:

                Fat = 0.08%
                Fat = 0.03%
                Fat = 0.06%

 What is the reason?

When analyzing water (instead of milk) results for FAT are close to zero, then Freezing point and Added water are completely wrong , therefore are not shown on the display.
There are variations in the results out of measuring range. We recommend making assessments with real milk samples only.
