and the ambient temperature. Enclose a copy of the data if the instrument should
be adjusted again by the factory.

4.0 VERIFICATION AND CORRECTION OF SWITCH POSITION
Now weigh the rest of the material sample, store it in more humid or drier
ambient conditions than where your calibration has been carried out. Do not
forget to adapt the measuring device to the corresponding temperature. Then
weigh your pile once more, calculate the moisture value by means of weight
applying the formula of control value calculation, measure this moisture value
and compare the result with the display

Please note: Checkline Europe provides special versions of P2, P4 and LM5
adapted to certain products. Refer to additional information on leather, page 10.
5.0 MEASURING
METHOD
Even if the kiln drying method is the only measuring procedure appropriate for
verification according to DIN 20287 it is time consuming, in-situ application can
very seldom be carried out; the method also has the disadvantage that the
samples are destroyed. Checkline Europe has developed the P2, P4 and LM5
generation – a measuring method which provides exact measuring results within
seconds. Yet it is not possible to develop a measuring device that is ideal under
every single condition; even P2, P4 and LM5 have a certain limited range to
provide optimum results. In order to minimize incorrect applications resulting from
that fact we have provided you with a list.
