BEFORE YOU BEGIN

Button Functions

!Read Button - Reads the percent moisture con-

tent value %MC when the meter is in the

portable mode. Turns the meter on in the

continuous mode.

@Calibration Check Button - Checks the meter

calibration. Displays the average of up to 100

accumulated readings; displays the highest

stored reading; erases the readings (portable

mode only). Turns the meter off in the continu-

ous mode.

#Set-Point Decrease Button - Allows you to

decrease the set-point to a lower value.

$Set-Point Increase Button - Allows you to

increase the set-point to a specific %MC. A

buzzer will alert you if the meter reads higher

than the selected %MC. Also operates the back-

light in the portable mode.

When the battery is replaced, the meter displays its

software version for one second and then turns itself

off. After replacing the battery, you must reset the

meter as described on page 6.

TO USE THE METER IN THE

PORTABLE MODE:

Please read this section carefully. In the portable mode, the

FX-2000 has different functions than in the continuous mode.

CHECK CALIBRATION

hRemove the probe from the top of the meter.

hPress and hold the read button !and check button @

simultaneously. Meter is in calibration if it displays “12”

(± .2) regardless of the scale setting.

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.

CHANGE THE SET-POINT

hTo change the set-point value press the set-point increase

button $. The meter will display the current set-point

value.

hTo scroll forward to a higher value, hold the set-point

increase button $while the current value is displayed

and scroll up to the set-point value desired.

hTo scroll backward through the set-point values, press and

release the set-point increase button $. Within one sec-

ond press and hold the set-point decrease button #.

hContinue to hold the set-point decrease button #and the

set-point value will decrease.

hWhen scrolling in either direction, release the button to

stop at your desired set-point.

If the meter reads a %MC higher than that of the set-point,

a buzzer will sound.

TO CHECK ACCUMULATED

READINGS

This feature allows you to view the total number of all

accumulated readings, the average of those readings, and the

highest stored reading.

hTo add a reading to the sum of all previously stored readings,

release the read button !within 2 seconds. If you press

and hold the read button !, the meter will repeat its read

cycle, but will not add a new reading to the storage until

the button is released.

hTo view the readings press and release the calibration

check button @. First the meter displays the number of

accumulated readings for one second, then the average of

those readings for two seconds. Then it displays the highest

stored reading for two seconds. The total “cycle” time is

five seconds.

FX-2000 B&W manual:FX-2000 B&W manual 50406Q5 12/10/08 8:57 A

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 back-

light. If no readings are stored, it will display “0”.

The backlight will be deactivated automatically when chang-

ing from the portable mode to the continuous mode.

Use of the backlight should be kept to a minimum to avoid

draining the battery.

FX-2000 B&W manual:FX-2000 B&W manual 50406Q5 12/10/08 8:57 A

TO RESET METER

hPress and release the calibration check button @.

hWithin one second, press and hold the set-point decrease

button #.

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 repre-

sents 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.

FX-2000 B&W manual:FX-2000 B&W manual 50406Q5 12/10/08 8:57 A

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 follow-

ing the procedures above. This will make the moisture

distribution in the sample more uniform.

FX-2000 B&W manual:FX-2000 B&W manual 50406Q5 12/10/08 8:57 A

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 read-

ings are very useful guidelines for safe storability of hay.

FX-2000 B&W manual:FX-2000 B&W manual 50406Q5 12/10/08 8:57 A

TestEquipmentDepot.com

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)
