Modifying the moisture indications readings
This option is used for the modification (adjustment)
of moisture readings by increasing or decreasing
the displayed value (of the device) by the same
value in the entire measuring range. However, by
modifying the displayed values we are changing
the measuring range limits, i.e., when we make
an adjustment by „+2%" the measuring range will
change from 10%-80% to 12%-82%.
The modification is made, if the user finds that
for a given force of the pressed bale the tool has
a tendency to over- or understate the results by
the similar value in the entire moisture range. This
modification is useful when the bales of hay/straw
are poorly or very hard pressed, because the HMM
curve is based on an average compression strength.
