Adjusting the Calibration of the Meter
Superpro is factory calibrated for every crop using the official methods of measuring moisture content as
compiled by ISTA (International Seed Testing Association). The calibration scales are compiled using
samples of crops grown in normal conditions. Differing growth factors between years and between
varieties can have an effect on the electrical characteristics of the crop and it can therefore be necessary to
recalibrate the meter. To avoid disputes, it is strongly recommended that Superpro is checked against the
meter being used by the buyer of the grain (using grain from the same sample in both cases), and adjusted
as required.
Each crop calibration in the meter can, if necessary, be adjusted individually up or down by up to 3.9% in
increments of 0.1%. This is achieved as follows:
1. Turn on the meter by pressing ON/TEST.

8. An asterisk (*) will appear at the end of the name of the crop if adjustments have been made
compared to the factory calibration.
