– in order to measure proper volume of grain use the
cap with 24 mm screw which is used as dispenser
as well. You should take one full dispenser, spread
the grain on the grinding mechanism of the meas-
uring chamber and tighten the knob of the cham-
ber until it stops on the knob’s block system limit
extending from the measuring chamber. After
that select the species from the list of the device
and start measuring pressing button;
– measuring the sample with the dispenser and
tightening the knob properly is necessary in or-
der to obtain accurate results;
– the measuring chamber should be thoroughly
cleaned especially when you change the species of
grain and when the samples have different, usually
increased moisture;
– grinding device should be thoroughly cleaned af-
ter measuring samples which have increased hu-
midity;
– if humidity is increased (more than 25%), it is nec-
essary to avoid the situations when too cold grain
is inserted into the chamber, because water vapour
condenses on the surface of the grain. In these
situations it is necessary to mix the grain properly,
take the sample and wait a few minutes until the
temperature of the grain increases. Moreover, the
first measuring result should be ignored, the final
result should consist of an average result of the fol-
lowing three measurements;
– when mounting the knob on the threaded shaft of
the measuring chamber, you should pay special at-
tention to proper interlocking of the thread;
