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
determine obtaining a correct result. Cha,
screenings 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
waythemeasuring chamberislledisimportant
and determines measurement accuracy. Fill the
dispenser with small surplus and remove the
damper always the same way,
– While measuring, when „Is chamber empty?”
message displays, check whether the chamber
is empty, clean and dry and then press
button to conrm, because the device reads
the parameters of the chamber before it is lled
with grain,
– The nal result of measuring should be the average
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
temperature 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
temperature 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
tested 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-
FICATION OF MOISTURE INDICATIONS ).
