The instrument is calibrated ( factory adjusted ) in the incorporated scale. The scale are developed on the
basis of official methods of measuring the moisture content determination. The scale are compiled on the
basis of samples which represent the common grown crops in normal conditions. Growth factors which
deviates from the natural standards will have an effect on the electrical characteristics of the hay/straw and
it can therefore be necessary to recalibrate.

Storage and Advice for General Usage
It is recommended that you store the instrument in the enclosed transport packaging, that the instrument is
not exposed to large temperature fluctuations and that it is kept free of moisture.
If the instrument is taken into a warmer environment from a cold storage location, it is recommended that
one allow the unit to acclimatise in order that condensation does not affect the result of the
measurement.At the end of the season, wipe all surfaces with a well-wrung damp cloth and remove the
battery from the unit.
