FX-2000 B&W manual:FX-2000 B&W manual 50406Q5 12/10/08 8:57 A
If you check the calibration and 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 you have a fresh battery and the instrument still does not indicate an acceptable calibration, return it to DELMHORST for service.

hTo erase all the accumulated readings, hold the calibration
check button
@ for more than 5 seconds until the meter
displays “0”.
hTo keep the accumulated readings in memory, release the
calibration check button
@ before the total cycle time is
complete.
The meter will accumulate up to 100 readings. After all 100 readings are stored, it 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 calculation of average or highest reading.
TO OPERATE THE BACKLIGHT
hPress and release the calibration check button @. Within
one second, press and hold the set-point increase button
$.
hHold the set-point increase button
$ until the backlight
turns on. 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.
hThe backlight will remain activated while the meter is off
and will light up when any function is activated.
hTo deactivate the backlight, repeat the same steps taken to
activate it.
If there are 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.
Use of the backlight should be kept to a minimum to avoid draining the battery.

hThe meter will reset itself and display “222.” It will also
reset the set-point to 19% and clear all of the readings stored in memory.
Note: The meter will also reset itself if you change from the portable mode to the continuous mode.
TAKING A READING
Testing Baled Hay
hConnect the probe to the external connector on the top of
the meter
^.
hInsert the probe into the bale.
hPress the read button
!. The meter displays the %MC for
two seconds.
Notes
hThe 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.
hPartially 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.
hIf you are testing high density bales, we recommend using
the H-4 handle with the 830-2 10" prod, 830-3 18" prod, or the 830-4 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.
hWhen using the 36" prod, be sure to guide the prod into
the bale with one hand while pushing on the H-4 handle.

Testing in the Windrow
There are three ways to test moisture content in the windrow:
Test A
hAttach the #831 short pin prod to the H-4 handle and
connect the handle to the external connector on top of the meter.
hPrepare a representative sample by collecting hay from
various parts of the windrow.
hPlace hay in a non-conductive container (such as a 5 to 10
gallon plastic pail) and apply the short pin prod to the hay.
hPress down on the electrode to make firm contact with the
hay sample.
hPress the read button
! and take a reading.
hMix the sample once again and take at least two more
readings. Use the highest readings.
Notes
hWhenever pressure is being applied on the electrode, be sure
that the points of the electrode are touching nothing but the hay.
hRepeat the steps above if considerable variations are found
in the meter readings. To reduce these variations, chop the hay, mix it thoroughly and take several readings by follow­ing the procedures above. This will make the moisture distribution in the sample more uniform.

Page 9
Test B
hAttach the #831 short pin prod to the H-4 handle and
connect the handle to the external connector on top of the meter.
hPress down on the prod to make firm contact with the hay
sample.
hPress the read button
! and take a reading.
hMake several tests on the hay exposed to the sun, then
turn the windrow over and make an equal number of tests on the hay that had been closer to the ground. Use the highest readings.
Notes
hMake sure that the points of the electrode are not touching
the ground. The electrode points should make contact with the hay only.
Test C
hSelect up to five large, slower-drying stems from a section
of the windrow.
hPlace them one at a time across two adjacent points on
the #831 short pin prod.
hThe average of these stem readings should be about two to
five points higher than the actual moisture content.
Notes
hRepeat these steps in different parts of the field and pay
special attention to the areas where the hay is heaviest.
hThe 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.
FACTORS AFFECTING YOUR READINGS
Because of the many variables that affect the electrical meter readings, the indicated moisture content 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 the light of the density of the bales, anticipated handling and storage, and prevailing climate conditions.
Range of Moisture Content
The 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. Delmhorst 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 mostly 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 few high readings indicate 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.
Hay Temperature
The FX-2000 has been calibrated at 80°F on various samples of different types of hay, mostly alfalfa, and on different cuttings and mixtures. The higher the temperature of the sample, the higher the meter readings will be. Temperatures lower than 80°F cause lower meter readings. The correction is approximately 1% point for every 20° difference. Refer to chart on the next page:
Hay temperature Add to reading Subtract from reading
20°F/-7°C 3 -­40°F/ 5°C 2 -­60°F/15°C 1 -­80°F/30°C 0 0 100°F/40°C -- 1 120°F/50°C -- 2 140°F/60°C -- 3
Example
Meter reading: 22% Temperature: 40°F/5°C Moisture Content: 24% (22 + 2)

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 are the
variations. The more curing 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 testers applies to bales of normal “average’ density. Generally:
hDenser bales may yield readings 1-2% points higher.
hLooser bales tend to yield 1-2% point lower.
hTests in stacks usually yield readings 2%-3% lower.
hTests on grass hay may yield readings about 3% lower.
Baling should be done according to the lower meter reading.
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 H-3 handle as described on page 7.
Use of Preservatives
Hay preservative or stabilizers may also have an affect on meter readings. Normally a bale of hay treated with preser­vative will read higher than a bale of the same hay that had not been treated. The readings typically increase by 2-4% points, and 24-48 hours after treatment, the readings between the bales tends to equalize.
FX-2000 B&W manual:FX-2000 B&W manual 50406Q5 12/10/08 8:57 A
www.GlobalTestSupply.com
Page 12
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.
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%.
More tests must be made whenever the variations among readings are greater. 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.
It is extremely important to note the high readings and the frequency at which they occur.
TO USE THE METER FOR CONTINUOUS MONITORING
To install the meter:
hAttach 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.
hGround the other lead. A replaceable fuse protects the circuit.
The meter can also be powered independently of the trac­tor’s electrical system by using a 12V, (Eveready 732 or equivalent) all-purpose battery.
hSelect a location in the cab where the display can be easily
viewed while baling. Install the stainless steel mounting loop and slide the meter onto the loop.
hConnect the power cable to the meter.

To install the #1986 bale sensor:
Installation on a conventional small square baler:
hLocate a spot on either side of the bale chamber, approxi-
mately halfway up the side of the bale, 12" to 24" in from the rear of the chamber. The sensor pad and crop diverter need to be located in the baler chamber as close to the plunger face as possible. The sensor must mount flat.
hTape the drilling template onto the location. Make sure
before drilling that when the bolts come through the side of the chamber that they do not interfere or touch any other pieces of metal. Using the size drill indicated, drill the mounting holes. File any burrs from the holes.
hInstall 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).
hSlide the coaxial cable lugs between two flat washers.
Secure all six nuts.
hSecure the coaxial cable at several points with tape or
nylon ties so that it does not interfere with any moving parts of the baler.
hConnect the coaxial sensor cable to the meter.

Installation on an Inline or Center Line small square baler:
hFollow instructions for installation as above.
If placing the #1986 in the center channel you may need to cut an opening from the outside to be able to tighten down the nuts and secure the wire or use longer bolts and spacers.
Installation on a large or mid-size square baler:
When installing the #1986 on a large square baler, use the same guidelines as above. However, we recommend 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.
Installation on a John Deere Round Baler:
hLocate a spot on the right hand side of the bale chamber,
approximately 4.5" up from the bottom of the frame. The back edge of the sensor pad should be vertical so that the top rear corner of the sensor pad is approximately 3/8" forward from the rear edge of the upright frame tube.
hFollow instructions for installation as above.
Make sure that the beveled edge of the sensor pad is fac­ing the front of the baler.

TO USE THE METER IN THE CONTINUOUS MODE
hChange the set-point to the desired value as described on
page 4. This must be done prior to turning the meter on.
hPlug the external power supply into the side of the meter.
This will automatically put the meter in the continuous mode. Once power is supplied, the backlight will turn on and remain on until the external power is removed.
hTurn the meter on by pressing the read button
!. A deci-
mal point will display for a few seconds and then the meter will begin displaying the average and highest readings.
When the meter is operating continuously, it takes two readings every second, and accumulates eight readings before calculating their AVERAGE and HIGHEST val­ues. After all eight readings have been taken, the meter will begin a new read cycle. The meter displays the aver-
age as Axx.x and the highest as xx.x alternately for two seconds each.
hTurn the meter off by either removing the external power
supply or pressing and holding the calibration check button
@ until the meter is off. The backlight will stay on until
the power supply is removed.
Notes
hStart tractor before powering up meter.
hDisconnect meter before shutting down tractor.
ABOUT YOUR READINGS
The meter reads between 6% and 40%. Readings below 6% are displayed as “.0” and are used in calculation as 7.5%; readings above 40% are displayed as “99.9” and are used in calculation as 45%.
Readings obtained while using the 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.

We recommend 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.
CARE OF YOUR METER
To keep your meter in good working order:
hStore your meter in a clean, dry place. The optional
protective carrying case is an ideal storage place when the meter is not in use.
hChange the 9-Volt battery as needed. Continued use with a
low battery may cause the meter to go out of calibration.
hClean the meter and probe with any biodegradable cleaner.
Use the cleaner sparingly and on external parts only. Do
not immerse the meter or any prod in water.
hRemove the battery if the meter will not be used for one
month or longer.
