Instructions
This section explains how to use the Farmpro
Prepare and Make a Measurement
Inspect the two parts of the grinder cell to make sure they are clean and empty.
If the temperature of the grain sample differs a great deal from that of the meter, e.g. when taking
measurements directly from the dryer, it is recommended to preheat the meter as follows:
a. Fill the test cell with the desired crop, grind it and wait approx. 1-2 minutes.
b. Proceed with the normal testing procedure as detailed below..
1 TURN ON DEVICE Press the Power button “ON/TEST”
2 SELECT ‘Measure’ and press the ON/TEST button
Select the crop to be tested by using the arrow keys ⇑ or ⇓.
To select a different crop press the ESC/OFF button to return to MEASURE and use arrow keys ⇑ or ⇓ to
cycle through the options.
3 Fill the sample into the grinder
Using the built-in measuring cups (9ml and 11ml) in the upper part of the grinder to measure out the
quantity required of the crop to be tested. The quantity is shown in the display alongside the crop name
(9ml and 11ml).
4 Grind the sample and press the ‘ON-TEST’ button
Screw on the upper part of the grinder and rotate it clockwise until the two stop pins meet. It is important to
rotate to this point to obtain the correct test result.
Important: Never screw together the upper and lower part of the grinder when the measuring
chamber is empty as serious damage can be done to the fine grooves of the grinding discs.
Ver 1.1.0
Page 6/12

Press ON/TEST immediately. A series of asterisks will appear across the screen, followed by the moisture
reading.
The analyser will take ~10sec to measure the moisture content and calculate the temperature
compensation and hereafter display the result.
A new reading can be made by emptying and cleaning the test cell and filling it with a new sample. Do not
re-test the sample without first emptying and refilling.

Note: In order to ensure correct measurements, clean both grinder discs thoroughly with the
enclosed cleaning brush after each measurement. Remnants of sticky or moist material can
be removed by grinding a dry grain sample.
Note: When grinding crops with high water content there may be a risk of the two grinder discs
touching one another so that the display reads Hi. If this happens, carry out a new
measurement with an increased sample size. Try with approx. 2-3 ml more than the quantity
specified in the display. In particular, when measuring maize with more than 20 % moisture
(and some grass types), 18ml (2x9 ml) must be measured out for grinding, as stated in the
display.
Note: If the temperature of the grain sample differs a great deal from that of the result in the
unit, e.g. measurements directly from the dryer, it is recommended to preheat the tester as
follows:

1. Fill the grinder with the desired crop, grind and wait 1-2 minutes before pressing the ’ON-TEST’
button
2. Read the results on the result screen
Adjusting the Calibration of the Meter
Farmpro is factory calibrated for every crop using the official methods of measuring moisture content as
compiled by ISTA (International Seed Testing Association). The calibration scales are compiled using
samples of crops grown in normal conditions. Differing growth factors between years and between
varieties can have an effect on the electrical characteristics of the crop and it can therefore be necessary to
recalibrate the meter. To avoid disputes, it is strongly recommended that Farmpro is checked against the
meter being used by the buyer of the grain (using grain from the same sample in both cases), and adjusted
as required.
Each crop calibration in the meter can, if necessary, be adjusted individually up or down by up to 3.9% in
increments of 0.1%. This is achieved as follows:
1. Turn on the meter by pressing ON/TEST.
2. When MEASURE appears in the display use the arrow keys ⇑ or ⇓ until CALIBRATION is displayed.
3. Accept this choice by pressing ON/TEST.
4. Use the arrow keys ⇑ or ⇓ to select the crop that is in need of calibration adjustment.
5. Accept this choice by pressing ON/TEST. The numeric value +0.0 is shown in the display (factory
calibration).
6. Use the arrow keys ⇑ or ⇓ until the desired calibration adjustment value is displayed. Adjustments
can be made in the range from -3.9% to +3.9%.
7. Accept the selected calibration adjustment value by pressing ON/TEST.
8. An asterisk (*) will appear at the end of the name of the crop if adjustments have been made
compared to the factory calibration.
Farmpro Settings and Menu´s
The Farmpro has a number of settings that can be reached by doing the following:
Ver 1.1.0
Page 8/12

1. TURN ON DEVICE
2. Use the arrow-keys to choose between the menu settings
The device have four menus:
MEASURE
The menu measure is used to choose the crop to be tested.
BATTERY
This menu will give you an overview of the battery level.
CLEAR AVERAGE
This menu is used to clear the average of the last five measurements done.
1. Turn on the meter by pressing ON/TEST.
2. When MEASURE appears in the display use the arrow keys ⇑ or ⇓ until CLEAR AVERAGE is displayed.
3. Accept this choice by pressing ON/TEST. OK will appear in the display followed by an automatic return to
MEASURE.
CALIBRATION
The calibration menu is used to recalibrate the meter. Differing growth factors between years and between
varieties can have an effect on the electrical characteristics of the crop and it can therefore be necessary to
recalibrate the meter. See page 8.
Some more valuable information about the moisture
meter
Using the averaging facility
1. Due to the changing nature of grain when being harvested or dried, it is recommended to take several
readings. These will automatically be used to create an average reading.
2. It is recommended to take 3-5 measurements from the same batch of grain and use the average as the
true moisture content of the grain.
3. Remember to empty, clean and refill the test cell between each reading.

Battery
The meter is supplied with a 9-volt alkaline battery. This should be installed in the compartment on the
underside of the meter. When the battery is in need of replacement the message Replace battery will
appear on the display.
Only replace it with a similar high quality 9-volt alkaline battery. Removing the battery has no effect on the
information stored in the meter.
9-volt batteries should not be thrown away with trash. This may risk contact with other batteries or pieces
of metal which could lead to danger.
In case of battery leaking please remove carefully by using gloves. After removal please clean the device
carefully with a clean cloth.
Storage and Advice for General Usage
It is recommended that you store the meter at all times in the carrying case provided, so that the instrument
is not exposed to large temperature fluctuations and that it is kept free of moisture. If the instrument is
taken into a warmer environment from a cold storage location, it is recommended that you allow the unit to
acclimatise so that condensation does not affect the results of the measurement. At the end of the season,
wipe all surfaces with a well-wrung damp cloth and remove the battery from the meter. Clean all parts of
the grinder mechanism and lubricate the spindle with a thin layer of non-corrosive oil.
Auto Turn OFF time - Setting
Our Farmpro is pre programmed to Turn-OFF after approximately 90 seconds of inactivity.
If the device turns off by itself while using it please turn on the meter by pressing ON/TEST.
How to make your own grain calibration.
If you need to make a calibration scale for a particular crop that is not included in the meter, this can be
done as follows:
1. Turn on the meter by pressing ON/TEST.
2. When MEASURE appears press ON/TEST again.
3. Use the arrow keys ⇑ or ⇓ scroll through the crop options until Bit is displayed.
4. Fill the test cell with a sample of the desired crop for which you know the moisture content, grind
the sample and perform the test as described earlier.
5. Note down the value which appears in the display, eg. 03.65, and the temperature, eg. 19C, together
with the moisture content in the crop. Perform this process repeatedly using samples with different
levels of known moisture content until the calibration scale meets the range and requirements
needed. The more samples that are used the more accurate the calibration will be. Try always to use
samples at the same temperature.
6. Plot the values on a graph, either manually or using Excel, with moisture content on the y-axis and
Bit on the x-axis and draw a line or curve that best fits the points. The calibration is now completed
Ver 1.1.0
Page 10/12

and moisture contents can now be read off the y-axis for any Bit value measured using subsequent
samples of the same crop in the meter.
