Batteries are included, but need to be installed before
using the meter (see chapter 5 „BATTERY RE
PLACE ENT”). The battery compartment is on the
bottom side of the meter.
A display and a keyboard are on the front panel.
The measurement chamber above the display is
where tested seed is to be placed. There is a temper-
ature sensor on the bottom of the chamber.
Device is placed in plastic carrying case for multiple
use. t is made of material resistant to atmospheric
conditions, most chemical substances and allowing
easy cleaning.

PRELI INARY RE ARKS

1. Working according to manual will enable to ob-
tain expected accuracy and recurrence in mois-
ture measurement.
t is recommended to make three measurements. The
avearge of three measurements is the nal result.
2. Temperatures of sample and instrument should be
similar (sensor reacts with some delay).
3. Cleanness of sample for measurement has an in-
uence on obtaining accurate result. Sample
should not contain husks, tailings and dirti-
nesses.
4. You should check if there are no seeds in measure-
ment chamber before work. You should remove
any remainings from earlier measurement from the
chamber. Before turning on an instrument meas-
urement chamber should be clean and empty.
5. The way of lling the measurement chamber is
important and may inuence precision of meas-
urement results.
6. Producer suggests using alcaline batteries. The
electrolite which comes out of ordinary battery
after exhausting may damage the device. Alcaline
battery works longer and there is no risk of outow
of electrolite.
7. When the limit ranges of measurement are ex-
ceeded the display shows:
„<8%” (below range), when moisture of measured
sample is lower than 8%.
„>35,0%” (above range), when moisture of measured
sample is higher than 35%.
8. f important variations of readings appear in com-
parison with laboratory results of the samples, you
should use modication mode (see the chapter 4:
„DATA ODIFICATION”).

11CHAPTER 2 | PREL M NARY REMARKS
EN
To get skill in usage of device you should make several
measurements (for example with one kind of seed) and
notice results, to observe the spread of results.
We recommend reading the chapter 3 „ EASURE-
ENT” and follow these rules in practise.
ATTENTION!
Results obtained with this device can not be used for trade calculations.

12 CHAPTER 2 | PREL M NARY REMARKS
CHANGE OF THE LANGUAGE (optional)
f you want to change the language please press „OK”
button while the tester is turned off. Pressing the but-
ton constantly please turn the tester on by pressing
the „ON / OFF” button. Using the arrows „▲”, „▼” choose
the language: Hungarian (HUN), Czech (CZE), Polish
(POL), Spanish (ESP), French (FRA), German (DEU), Eng-
lish (GBR). Conrm with „OK” button.

EASURE ENT
EN

The procedure of measuring the grain humidity is
following:
a) Turn on the power supply with the red „ON/OFF”
button.
The name of the device will be shown for a while on
the display and then the model and serial number.
The name of the last measured sample will always ap-
pear afterwards, for example „rye”.
b) The appropriate species of grain should be chosen
using „s” or „t” buttons.
c) Having chosen the name press „OK” button.
Under the name there will be the instruction
„PLEASE WAIT” displayed for a short time (during
this time the device measures the electrical capacity
of the empty chamber).
ATTENTION!
While the instruction „PLEASE WAIT” is displayed
the measurement chamber should be empty and
clean, as well as while turning on the power sup-
ply of the device. During this time the measure-
ment chamber should not be touched. You
should not put your hand inside or put any ob-
jects in.
d) When the instruction „pour in seed” appears you
should put the measured seeds into measurement
chamber using the dosage tube.
Filling the measurement chamber using the
dosage tube.
The slider should be put into the dosage tube’s slot
until its semicircular edge suits the external edge of
the tube.
Next put the seeds into the dosage tube until it is en-
tirely lled. The surface of the poured seeds and the
upper edge of the dosage tube should be at the same
level.
Not quite lling the dosage tube can cause a read-
ing error. Overlling the dosage tube will have
a weaker inuence on the reading.
ATTENTION!
You cannot press the seeds in the dosage tube.

15CHAPTER 3 | MEASUREMENT
EN
Having performed these actions you can put the
dosage tube on the measurement chamber of the
meter (on the lower edge of the feeder there is a spe-
cial slant). You should then pull out the slider, which
will cause the sample to fall into the measurement
chamber.
ATTENTION!
While pouring the seeds you should pull out
the slider with a steady, but decided movement
which lasts about 1 second.
Upper edges of the measurement chamber (red
elements) should be completely covered by
seeds after lling.
e) Having lled the measurement chamber you
should not move or shake the device. You should
only press the button „OK”.
Under the name of the sample there will be the in-
formation: „analysing” displayed. After a short
time the result of the measurement will be shown –
the percentage of humidity and temperature in C
degrees. (the final humidity reading will appear
after the temperature’s influence is taken into ac-
count).
f) After measurement you should empty the cham-
ber and press „OK” button.
The command „pour in seed” will be displayed. t
means, you can repeat the measurement for the same
sample or check the humidity for another sample (of
the same species).
g) To choose another species (another name of the
sample) you should press the button „CAL/CANCEL”.
h) After nishing measurements the tester should be
turned off by pressing „ON/OFF” button.
f the tester is not being used, it will turn off auto-
matically after 3 min.
ATTENTION!
Please remember, to pour seeds into the meas-
urement chamber only after the command „pour
in seeds” is displayed.

DATA ODIFICATION
EN

The tester’s user can modify the data (calibrate the
device), which means that they can correct the coded
humidity curves for each species, which have been
prepared basing on the comparison with drier
method.
To make the required corrections you should turn on
the power supply with, ”ON/OFF” button while the
button, „CAL/CANCEL”is pressed.
That starts a special mode of the device, which allows
to introduce or delete the corrections in the device’s
memory – „shortened modication” will be dis-
played.
Using keys „s” or „t”, you can choose needed option:
”modication” or „erasing”, then conrm using
„OK” button.
1. ODIFICATION ODE:
It consists of modifying (correcting) the tester’s
readings by increasing or decreasing the device’s
readings by the same value in all the measuring
range. „ odication” is performed if the user
states that the device has a tendency to increase
or decrease the readings in all the measurement
range.
After choosing this function („OK” button), the name
of the last measured sample will be shown, which you
can change using „s” or „t” buttons.
Having chosen the needed name you should press
„OK” button again. The information: „change: 0,0
%” will appear. Now using the buttons „s” or „t” you
can introduce the values by which you want to mod-
ify the readings for the chosen species, for example
+1,2%.
Having introduced the chosen value once again press
„OK” button, and the information: „change +1,2%?.”
will be displayed.
• if you want to approve a change in the memory,
press „OK”, and the inscription „Ok” will appear,
which means that the changes have been saved in
the memory permanently,
• if you want to cancel changes, you press „CAL/CAN-
CEL”and then the information „cancel” will be dis-
played.

You can leave the modication mode by turning off
the power supply.
ATTENTION!
The name for which the modication has been
made, is marked with „*” sign.
2. ERASING ODE:
This operation restores the factory settings for the
chosen sample name (it removes all the correc-
tions for one species).
To select ERASE DATA, hold down the „CAL/cancel”
key and turn on the power with the „ON/OFF” but-
ton, then press the „UP” button and accept the
ERASE option by pressing the „OK” button.
After you’ve accepted the password in the modica-
tion mode menu the name of the last tested sample
will appear. That can be changed using or 
After you’ve accepted the selected name the „OK”
message will appear. At this point all adjustments will
be removed. The „*” symbol will be also removed
with the previously modied type of grain.
The „OK” message will appear and all adjustments
will be removed. The „*” symbol will be also removed
with the previously modied type of grain.
Pressing „CAL/CANCEL”will cause the canceling of this
operation and the information „CANCEL” will be dis-
played. You can leave the modication mode by turn-
ing off the power supply.
