INSTRUCTIONS
FOR MEASUREMENTS
SECTION

18
Following the manual as well as experience gained
in time will largely facilitate reaching the expected
accuracy and repetition of sample moisture measurements.
– size of grains and purity of test sample deter-
mine 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 aect 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 important and determines measurement accuracy.
Fill the dispenser with small surplus and remove 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 button to conrm, because the device reads the parameters 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 temperature sensor may react with a certain delay, since
the measurement chamber walls have brass lining,
SECTION 5 | INSTRUCTIONS FOR MEASUREMENTS

– each species has a dierent 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 signicant 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 modied (see: MODIFYING MOISTURE INDICATIONS).

In order to measure grain moisture:
a) switch the device on using , button. After a
short welcome message, the list of available species will appear on screen. The GMM mini will always indicate the name of the recently selected
species e.g Canola:
GMM mini
Choose species
Canola
Spring barley

b) use or button to select the species to be
tested and conrm with
c) when proper grain is selected, the device will ask
if the measurement chamber is empty and display
the current chamber temperature:
GMM mini

Is chamber empty?
Canola
at that point, check if the measurement
chamber is really empty and clean. Conrm
with
button,
d) when the status is conrmed, “Wait!” message will
be displayed for 1 second:
GMM mini
Wait!
Canola
do not touch the measurement chamber or
put anything inside when that message is
displayed because the device has to read the
chamber parameters before sample insertion,
in order to improve the measurement accuracy.
e) now the device is ready for sample insertion. Use
the dispenser to place grain inside the chamber.
(Placing the device on an even and rm foundation is recommended)

Filling the measurement chamber using the
dispenser:
Place the damper in the dispenser slot until it
locks. Place grain inside the dispenser with a small
surplus.
CAUTION!
If the dispenser is not lled completely, large
measurement error may occur. Overlling has
smaller eect on the result.
Do not compress grain in the dispenser.
When these actions are completed, place the lled
dispenser on the chamber (bottom edge of the
dispenser is specially proled to match the GMM
mini casing). Then remove the damper to ll the
measurement chamber with grain.
CAUTION!
To ll the measurement chamber, remove the
damper with a quick and smooth movement
within around 1 second (it is important that the
damper is removed always the same way).
When pouring our, remove the damper slowly, for
2-3 seconds, letting our to pour in portions into
the chamber.
Upper edges of the measurement chamber
must be completely covered.

The Draminski GMM mini grain moisture meter is capable of storing in its memory a few hundred dierent types of grain to be used in measurements. The
list of available species may vary in each device, depending on current oer in the country of purchase.
Current list of all available species is available on the
manufacturer’s website www.draminski.com in
Products / Moisture Meters / GMM mini.
Users of the Draminski GMM mini grain moisture
meters may activate additional species by entering
a special code in the main menu, after selecting the
option “Add species” (see: SETTINGS). In order to get
the special actvation code for a chosen grain type,
please contact us:
e-mail: wilgo@draminski.com

or your local authorised distributor of Draminski
products.
Contact us if you have a grain type not included in
the list on our website or a special grain type that
you would like to test. We are open for remote cooperation to add new species congured according
to your needs, that could be activated in your device
using a special code.
These unique possibilities make the GMM mini a universal device that will oer its unlimited capabilities
even after many years of use.

MODIFICATION
OF MOISTURE INDICATIONS
SECTION
9
32 SECTION 9 | MODIFICATION OF MOISTURE INDICATIONS
The Draminski GMM mini grain moisture meter
stores moisture curves for each species, determined
on the basis of results for normalised samples (bulk
density of grain and mass of 1000 seeds), which
guarantees accurate and repeatable results. However, it may happen that crop of a given year varies
from normalised seeds (due to various factors) and
departures may occur in moisture indications.
Such factors include:
1. seed formation and maturity
– weak and badly formed seeds = results under-
rated,
2. specic features of a given grain
– very tiny seeds = results underrated,
– very large seeds = results overrated,
3. degree of contamination and screenings = results
usually underrated,
4. degree of damage caused by pests and fungi.
NOTE!
Results of measurements should be compared only
with the laboratory drying-and-weighing test, not
with results of other moisture meters, as they may
be misleading.
The Draminski GMM mini grain moisture meter
enables the user to modify (adjust) measurement
indications.
In any case of modication, each grain type is
treated individually. When a modication is made,
an asterisk (*) will be displayed next to the grain
name, while during the measurement, a note will
be displayed in the upper right corner of the screen,
showing the value of adjustment of indication for a
given grain (the result will automatically reect the
modication):

We recommend restoring factory settings in
each following year and make another adjustment of indications (modication) if required.
When factory settings are restored, the asterisk
(*) next to the grain name disappears.

The moisture meter is powered with two AA type batteries 1.5V (LR6).
In order to change batteries:
– unlock the battery compartment cover on the
underside and remove discharged batteries by
pulling up the ribbon,
– place the ribbon inside the battery compartment,
– install new batteries according with their polarity
signs +/– (pressing the ribbon inside),
– close the battery compartment with the cover.
Press it carefully until it locks with a click, which
indicates that the battery compartment is properly
secured and there is no risk of batteries falling out.

46 SECTION 12 | FINAL NOTES
– Protect your grain moisture meter against direct
exposure to water. Avoid operating the device in
extreme temperatures. Do not allow moisture con-
densing out of the air to accumulate on metal parts
of the device, as it may aect measurements.
– At the end of the season, clean and dry the measur-
ing chamber carefully. Leaving the device dry guar-
antees long and reliable operation.
– Store the device in dry and warm conditions.
– Before any prolonged storage, remove batteries
from their compartment in order to eliminate the
risk of damage caused by battery leak. We recom-
mend using batteries of leading manufacturers.
– In case of any problems with the device or dicul-
ties in interpretation of the results, please contact
the manufacturer DRAMIŃSKI S.A. or your local au-
thorised distributor before sending the device for
repair.
– Do not dismantle the device on your own. Any
modications or repairs performed by unauthorised persons are unacceptable, as they may result
in permanent damage and void the warranty.
– Always check if the mini-USB port rubber cap is in
place, otherwise dirt might get inside and cause
damage.
