The GMS is ready for operation if a battery in the bat-
tery compartment is properly inserted (pay attention
to polarity).
Switch the device on with the help of the button.
a) you will hear 1 short sound signal and then greet-
ing text appears on the screen which shows the
name of the device, rmware version, calibration
version and serial number, e.g.:
www.draminski.com
Grain Master
Firmware v: 1.28 K:1.10
SN: GS010030
b) then there appears a list of available species and in
the upper part of the device there appears mod-
el of the device, battery level (when the device
switches on, it shows the last tested species), e.g.:
GMS
Select species
Rye
Canola
Spring barley
Oat
Note! If the battery is discharged to continue op-
eration, the device automatically signals it with a
message:
GMS
Replace battery
which means that you have to insert a new bat-
tery;
c) in order to save batteries, when no key is pressed
for a certain time, the device will go to a standby
mode and the backlight will turn o (that time can
be changed through the proper menu option –
see SETTINGS section). Press any button to return
to the operation mode;

d) if the GMS remains in the standby mode for several
minutes, it will shut down automatically (time set-
ting possible in menu). Then you will hear a short
sound signal informing that countdown from 10
to 0 is displayed on the screen – press any button
to stop, or the device will switch o automatically
to save power, e.g.:
GMS
Shutdown in 5 s
GMS
Shutdown in 1 s
e) e) for manual switch o, hold button for 5 sec-
onds or select “Shutdown!”in the main menu.

INSTRUCTIONS
FOR MEASUREMENTS

– 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 dierent, 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
rst measuring result should be ignored, the nal
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;

– size of grains and purity of test sample deter-
mine obtainment of 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 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 the hot device (e.g. after being
exposed to sunlight and vice-versa).
The temperature sensor may react with a time-lag
because of metal parts of the measuring chamber.
– every species has a dierent range of moisture;
however, when it is exceeded, it is signaled with a
particular sign, e.g.:
“<8.5%”(below the range), when the sample’s mois-
ture is less than 8.5%,
“>35.0%” (over the range), when the sample’s mois-
ture is more 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;
