■ Correction of calibration model for sugar contents deviation
When measuring fruits that have differences in the variety of fruit,
area/time of cultivation, environment temperature, and so on, if
the same calibration model applied to the instrument, predicted
sugar contents value may have a deviation comparing with actual
value measured from juice extraction. Before the first use of the
instrument for measuring a certain fruit, it is recommended to do
deviation correction first adjusting to the value of actual sugar
contents measured from juice extraction.
Though SUNFOREST H-100 has built in auto-correction function for temperature compensation, the measured
value may has still a deviation due to different environment temperature and time of cultivation. Therefore, it
would be better to have a deviation correction for calibration model before using the instrument at a new
environment. Required number of samples to be used for deviation correction are over 3 pieces at least
collected at each range of sugar contents i.e. low, medium, and high level. Also the average value to be applied
should be born out of more than 3 times of measurement by H-100 instrument.
■ Creation of a new calibration model
Under severe differences in the variety of fruit and area/time of cultivation, existing calibration model may not
be simply adjusted by deviation correction and would be no longer suitable for a new environment. In this
case, a new calibration model must be newly created by the user program provided by USB memory included
in H-100 product package.
With the user program provided, the user can create their own calibration model without complicated
procedure. For the creation of calibration model, refer to the user manual included in USB memory.
