INSTRUCTIONS
FOR MEASUREMENTS
SECTION 5

Following the manual as well as experience gained
in time will largely facilitate reaching the expected
accuracy and repetition of sample moisture meas-
urements.
– size of grains and purity of test sample deter-
mine obtaining a correct result. Cha, screen-
ings and dirt content within the sample should
be as low as possible.
– water remaining on top of the sample (e. g. dew)
can aect measurement result. Samples should be
aired before measurement to avoid it,
– the dispenser included in the set must be used
to dose a proper amount of grain because the
way the measuring chamber is lled is impor-
tant and determines measurement accuracy.
Fill the dispenser with small surplus and re-
move the damper always the same way,
– while measuring, when „Chamber empty?”
message displays, check whether the chamber
is empty, clean and dry and then press but-
ton to conrm, because the device reads the pa-
rameters of the chamber before it is lled with
grain,
– the nal result of measuring should be the aver-
age value of e.g. 3 recent tests of a given sample,
which is calculated automatically and displayed in
the bottom right corner of the screen (number of
measurements used for calculation of the average
value can be changed in the menu),
– make sure that the measuring chamber tempera-
ture is the same as the sample temperature (do
not pour cool grain into hot device (e.g. after being
exposed to sunlight) and vice-versa). The tempera-
ture sensor may react with a certain delay, since
the measurement chamber walls have brass lining,

– each species has a dierent range of measured
moisture. Results beyond the set range are marked
with a proper sign:
„<8.5%” (below the range), when moisture of tested
sample is lower than 8.5%,
„>35.0%” (above the range), when moisture of test-
ed sample is higher than 35%,
– if signicant departures are found in the result for
a given species, either too high or too low by a
similar value within the entire measurement range
in comparison with the drying-and-weighing test
method, indications must be modied (see: MODI-
FYING MOISTURE INDICATIONS).
