OPERATOR’S MANUAL
INSTALLATION AND SETUP
CONTINUOUS MONITORING INSTALLATION
Attach the red lead of the power cable to a positive (+) 12-volt supply point
controlled by the ignition switch, or attach it directly to the tractor battery.
Ground the other lead. A replaceable fuse will protect the circuit.
The meter may also be powered independently of the tractor’s electrical
system by using a 12-volt (Eveready 732 or equivalent) all-purpose battery.
Select a location in the cab where the display may be viewed easily while
baling. Install the stainless steel mounting loop and slide the meter onto the
loop. Connect the power cable to the meter.
467912130 BALE SENSOR INSTALLATION
Locate a spot on either side of the bale chamber approximately halfway up
the side of the bale, 12” to 24” in from the rear of the chamber. The sensor
must mount flat.
Tape the drilling template on the location. Using the indicated drill size, drill
the mounting holes. File any burrs from the holes.
Install the sensor plate with only the bale chamber wall between it and the
backplate. The beveled edge of the insulation must face the plunger
(opposite direction of bale movement).
Slide the coaxial cable lugs between two flat washers. Secure all nuts.
Secure the coaxial cable lugs at several points with tape or nylon ties so
that it does not interfere with any moving parts of the baler.
Connect the coaxial sensor cable to the meter.

OPERATOR’S MANUAL
BALE SENSOR LARGE OR MID-SIZE BALER
INSTALLATION
When installing the 467912130 Bale Sensor on a large square baler, use
the same guidelines as previously illustrated. However, it is recommended
that you add a 1/4” thick piece of strap iron in front of the sensor’s beveled
edge. This will provide additional protection to the sensor plate.
BALE SENSOR ROUND BALER INSTALLATION
Locate a spot on the side wall or tailgate on either side of the baler, as low
as possible to the bottom.
Follow the previous installation instructions. Be sure the sensor plate lies
flat with the beveled edge facing the pickup. The hay will begin to pass over
the sensor when the bale is formed to approximately 1/4 of full size.
BACKLIGHT OPERATION
Check button
Press and release the Check button. Within one second, press and hold the
Set-point Increase button. Hold the Set-point Increase button until the
backlight illuminates. The backlight will be activated and remain lit as long
as the meter remains on. After the meter turns off, the backlight will also
turn off. The backlight will remain activated while the meter is off and will
illuminate when any function is activated.
To deactivate the backlight, repeat the same procedure.
Set-point Increase button
If there are any readings stored in memory, the meter will run through the
check cycle while activating the backlight. If no readings are stored, it will
display “0”.
The backlight will be deactivated automatically when changing from the
PORTABLE mode to the CONTINUOUS mode.
IMPORTANT: Use of the backlight should be kept to a minimum to
avoid draining the battery.

CHECKING CALIBRATION
Remove the probe from the top of the meter. Press and hold the Read
button and Check button simultaneously. The meter is in calibration mode
when it displays “12.0” (+/- 0.2).
Read button
If the display does not read “12”, it is likely an indication of a low battery. If
this occurs, change the battery immediately. Continued use with a low
battery may cause the meter to go out of calibration. If a fresh battery is
installed in the meter and the instrument still does not indicate an
acceptable calibration, contact the DICKEY-john Service Department. Refer
to SERVICE AND MAINTENANCE for additional information.
Check button
CONTINUOUS MODE
Change the SET POINT to the desired value (refer to CHANGING SET
POINT). This must be accomplished prior to turning the meter on.
Plug the external power supply into the side of the meter. This will
automatically put the meter in CONTINUOUS MODE. Once power is
supplied, the backlight will turn on and remain on until the external power is
removed.
When the meter is operating continuously it takes two readings every
second and accumulates eight readings before calculating the AVERAGE
and HIGHEST values. After all eight readings have been taken, the meter
will begin a new read cycle. The meter will display the average as Axx.x and
the highest as xx.x alternately for two seconds each.
Turn the meter off by either removing the external power supply or pressing
and holding the Check button until the meter powers off. The backlight will
stay on until the power supply is removed.
IMPORTANT: The tractor must be started before powering up the
meter. Disconnect the meter before shutting off the
tractor.

CHECKING ACCUMULATED READINGS
This feature allows the user to view the total number of all accumulated
readings, the average of those readings, and the highest stored reading.
To add a reading to the sum of all previously stored readings, press and
release the Read button within 2 seconds. Pressing and holding the Read
button will repeat the read cycle but will not add a new reading to the
storage until the button is released.
Read button
Check button
To view the readings, press and release the Check button. The meter will
display the number of accumulated readings for one second, then the
average of those readings for two seconds. It will then display the highest
stored reading for two seconds. The total cycle time is five seconds.
To erase all accumulated readings, hold the Check button for more than
five seconds until the meter displays “0”.
To keep the accumulated readings in memory, release the Check button
before the total cycle time is complete. The meter will accumulate up to 100
readings. After all 100 readings are stored, the meter will not add new
readings until the memory has been cleared. It will also continue to display
the average of all 100 readings as a reminder that the memory is full.
Readings below 6% will be displayed as “.0”. Those above 40% will be
displayed as “99.9”. Neither will be added to the accumulated readings or
used in the calculation of average or highest reading.
RESETTING THE METER
Press and release the Check button. Within one second, press and hold the
Set Point Decrease button. The meter will reset itself and display “222”. It
will also reset the set-point to 19% and clear all the readings stored in
memory.
Set-point Decrease button
IMPORTANT: The meter will also reset itself if you change from the
PORTABLE mode to the CONTINUOUS mode.
TESTING BALED HAY
Connect the probe to the external connector on the top of the meter. Insert
the probe into the bale. Press the Read button. The meter will display the
%MC (percent moisture content value) for two seconds.
The hay prod is electrically insulated, except at the metal points near the tip.
The moisture content measured represents the hay in contact with the tip of
the prod only.
Partially cured hay may have wide variations in moisture content throughout
the bale. Readings should be taken in several different parts of the bale and
the highest readings used as a guideline. The arrangement and compaction
of hay fibers in a bale may have an effect on meter readings.
8 OPERATION
Dj FX-2000 Hay Moisture Meter
11001-1354-200511
OPERATOR’S MANUAL
When testing high density bales, it is recommended that you use the
467912120 handle with the 467912070 10” prod, 467912080 18” prod, or
the 467912100 36” prod. Using the handle/prod combination eliminates
excess stress on the instrument case that may occur when trying to insert
the prod into a high density or large bale.
When using the 36” prod, be sure to guide the prod into the bale with one
hand while pushing with the 467912120 handle.
TESTING IN THE WINDROW
When testing in the windrow, push down on the pressure button until the
palm of your hand touches the screw that holds the button in place. The
pressure button depresses a calibrated spring inside the handle. When the
screw touches the palm of your hand, the pressure applied on the sample is
27-30 lbs, which closely simulates the pressure in a standard bale of hay.
There are three ways to test moisture content in the windrow.
METHOD A
Attach the 467912110 short pin prod to the 467912120 handle and connect
the handle to the external connector on top of the meter. Prepare a
representative sample by collecting hay from various parts of the windrow.
Place the hay in a non-conductive container (such as a 5 to 10 gallon plastic
pail) and apply the short pin prod to the hay.
Press down on the electrode until the head of the screw, which holds the
pressure button, touches the palm of your hand. Press the Read button and
take a reading. Mix the sample once again and take at least two more
readings. Use the highest readings.
Read button
Whenever pressure is being applied on the electrode, be sure that the
points of the electrode are touching nothing but the hay. Repeat the
previous steps if considerable variations are found in the meter readings. To
reduce these variations, chop the hay, mix it thoroughly, and take several
more readings by following this procedure. This will make the moisture
distribution in the sample more uniform.
METHOD B
Attach the 467912110 short pin prod to the 467912120 handle and connect
the handle to the external connector on top of the meter. Apply the prod to
the hay in the windrow and press down on the electrode handle until the
head of the screw touches the palm of your hand. Press the Read button
and take a reading.
Perform several tests on the hay exposed to the sun. Then turn the windrow
over and perform an equal number of tests on the hay that had been closer
to the ground. Use the highest readings.
Make sure that the points of the electrode are not touching the ground. The
electrode points should make contact with the hay only.

OPERATION 9
OPERATOR’S MANUAL
METHOD C
Select up to five large, slower-drying stems from a section of the windrow.
Place them, one at a time, across two adjacent points on the 467912110
short pin prod. The average of these stem readings should be about two to
five points higher than the actual moisture content.
Repeat this process in different parts of the field and pay special attention to
the areas where the hay is the heaviest. The amount of variation found
among windrow readings as well as the average stem moisture should be
taken into consideration before the decision is made to start baling.
ABOUT THE READINGS
The meter reads between 6% and 40%. Readings below 6% are displayed
as “.0” and are not used in calculations. Readings above 40% are displayed
as “99.9” and are used in calculations as 45%.
Readings obtained while using the Dj FX-2000 in its continuous mode are
usually higher than those obtained when probing the bale by hand. Under
normal conditions, expect the continuous readings to be around 2-4 points
higher on average. Tests show this difference can be even greater,
especially on large square bales, depending on overall conditions.
Do not be concerned that such differences exist. However, it is important to
have a feel for what the difference is since conditions in the field change
rapidly.
It is recommended that you spot check the windrow and freshly made bales
to give additional information with regard to these differences and to help
establish the appropriate range for baling.

OPERATOR’S MANUAL
FACTORS AFFECTING READINGS
Due to the many variables that affect the electrical meter readings, the
indicated moisture constant should not be used as an absolute quantitative
measurement. Meter readings are very useful guidelines for safe storability
of hay.
Meter readings become more significant when they are considered in
regard to the density of the bales, anticipated handling of storage, and
prevailing climate conditions.
CURING
Before proper curing has taken place, wide variations in moisture content
should be expected in both recently-baled hay and hay in the windrow.
These variations will be exposed by meter readings taken on different parts
of the windrow or bale. The higher the moisture range, the wider the
variations will be. The more curing that has been allowed to take place, the
greater uniformity in moisture distribution can be expected.
The validity of the meter readings is closely related to the care spent in
sampling the hay to be tested. Whether hay in the windrow or baled hay is
tested, the number of tests made should be increased whenever the initial
readings show considerable variations.
DENSITY
The calibration of the moisture meters applies to bales of normal “average”
density. Generally:
•
•
•
•
Denser bales may yield readings 1-2% points higher.
Looser bales tend to yield 1-2% points lower.
Tests in stacks usually yield readings 2-3% lower.
Tests on grass hay may yield readings about 3% lower.
When testing baled hay, drive the prod across the slices of the bale, not
between them. This will ensure firmer and more uniform contact.
When using the short pin prod, uniformity of pressure from one sample to
the other is achieved by applying pressure to the “pressure button” at the
end of the # 467912040 handle as described in TESTING IN THE
WINDROW.

OPERATOR’S MANUAL
HAY TEMPERATURE
The Dj FX-2000 has been calibrated at 80OF on various samples of different
types of hay (mainly alfalfa) and on different cuttings and mixtures. The
higher the temperature of the sample, the higher the meter readings will be.
Temperatures lower than 80OF cause lower meter readings. The correction
is approximately 1% point for every 20OF difference.

RANGE OF MOISTURE CONTENT
The Dj FX-2000 is designed to test moisture in hay over a range of 6-40%.
Readings over 30% should be used only as a qualitative indication of high
moisture content. DICKEY-john moisture meters use the relationship
existing between electrical conductivity and moisture content in hay. As
moisture content increases, so does the conductivity.
Tests on hay at high moisture content, over 25%, are less accurate. This is
primarily due to the variability in moisture distribution. The reduced level of
accuracy in the high range does not significantly affect the usefulness of the
meter, as a high reading indicates that some action be taken to dry the hay
to avoid spoilage or even self-combustion.
While it is important to note the average of several readings, it is even more
important to note the high readings and the frequency at which they occur.
12 FACTORS AFFECTING READINGS
Dj FX-2000 Hay Moisture Meter
11001-1354-200511
OPERATOR’S MANUAL
SAMPLE SIZE
When testing baled hay, it is essential to take readings at several different
points in the bale. Hay moisture may vary a great deal in the same bale. For
example, at one point bale moisture may be 20% and at another over 35%.
Additional tests must be made whenever the variations among readings are
great. If there is a possibility of high moisture areas, samples from these
locations should be taken. Areas of high moisture content will spoil,
resulting in loss.
IMPORTANT: It is extremely important to note the high readings and
the frequency at which they occur.
USE OF PRESERVATIVES
Hay preservatives or stabilizers may also have an affect on meter readings.
Normally a bale of hay treated with preservatives will read higher than a
bale of the same hay that has not been treated. The readings typically
increase by 2-4% points, and 24-48 hours after treatment, the readings
between the bales tend to equalize.
Occasional higher readings may occur if, in addition to the effect of the
increased conductivity due to the stabilizer, the bales tested also show an
increase in temperature and “sweating”. As the stabilizer becomes more
thoroughly absorbed and the sweating subsides, the meter readings recede
to the initial level and will continue to decrease, assuming that the bale
becomes progressively dryer.
