3.0 HOW TO CHOOSE TYPE OF PRODUCT
Since there is no unified manufacturing process of the measuring products the
adjustment of the switch can not be standardized. But there is always the
possibility of having your device calibrated by Checkline Europe. In this case we
need a pile of your product (2 cm thick) size A4 in a plastic wrapping that is as
tight as possible. You can classify your products by means of a comparison
measurement applying methods appropriate for verification according to
DIN20287. Take a 2 cm thick pile with an average quantity of moisture size A5,
weigh some of the sheets and dry them in a drying stove. Store the rest of the
paper in a plastic wrapping to preserve the moisture. The dried sheets of paper
are weighed again. By using the following formula the absolute moisture is
calculated.
Caution! The dried sheets of paper must not be used for measurement again.
M
n : mass of sheets with an average moisture.
M
t
: mass of dried sheets
%F: calculated absolute moisture.

Now take the rest of the pile out of the plastic wrapping and measure it with your
measuring device. Adjust the switch until the most exact value can be seen on
the display and note down the position of the switch.
