OPERATION
CHANGING SET-POINT
To change the set-point value, press the Set-Point button. The meter will
display the current set-point. To scroll forward to a higher value, hold the
Set-Point button while the current value is displayed and scroll to the
set-point value desired.
To scroll backward through the set-point values, press and release the
Set-Point button. Within one second, press and hold the Scale button.
Continue to hold the Scale button and the set-point will decrease.
When scrolling in either direction, release the button to stop at the desired
set-point. If the meter reads a %MC (percent moisture content value) higher
than that of the set-point, a buzzer will sound.
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. When taking and storing
readings for a specific material, be sure to clear the meter before moving on
to the next scale if you do not want to group all of the readings together.
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.
CHECKING CALIBRATION
Press and hold the Read button and Check button simultaneously. The
meter is in calibration if it displays “11.1%” (+/- .2) on the scale, regardless
of the scale setting.
If the calibration is checked and the display does not read “11.1”, 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 and the meter still does not
indicate an acceptable calibration, contact the DICKEY-john Service
Department.

6 OPERATION
When the battery is replaced, the meter will display its software version for
one second and then power off. After replacing the battery, the meter must
be reset as described in RESETTING THE METER.
RESETTING THE METER
Press and release the Check button. Within one second, press andhold the
Scale button. The meter will display a reset sequence of “121” followed by
“8”, “1.1”, “11.1”. The last number, “11.1”, is a calibration check. Resetting
the meter clears the memory and restores default settings.
SETTING THE SCALE
Set the scale for #1 Lint Cotton or #2 Seed Cotton. To change the scale,
press the Scale button. The meter will display the current scale for one
second. Press and hold the Scale button to toggle between the two scales.
Release the Scale button to stop at the desired scale. Changing the scale
will automatically reset the set-point value to the default setting for that
particular scale. Default settings are as follows:
• Lint Cotton - 7.0%
• Seed Cotton - 12.0%
TESTING LINT COTTON
Attach the 467912000 Sample Cup Electrode to the connector on top of the
meter. Set the scale for LINT COTTON and select a set point. Place a small
quantity of lint cotton in the sample cup. Press the cotton firmly into the cup
with your finger. The cotton sample in the cup should be overflowing during
the test, even while you are pressing it with your finger.
Press the Read button and read the moisture content on the display. The
meter will display the %MC (percent moisture content value) for two
seconds. Readings below 4% lint cotton will be displayed as a negative
number. Readings above 16% lint cotton will be displayed as a blinking
16.2%. Both the underrange and overrange readings should be
disregarded. They will not be added to the accumulated readings or used in
the calculation of the average or highest reading.
TESTING SEED COTTON
Attach the 467912000 Sample Cup Electrode to the connector on top of the
meter. Set the scale for SEED COTTON and select a set-point. Place a
small quantity of cotton in the sample cup. Press the cotton firmly into the
cup with your finger. The cotton sample in the cup should be overflowing
during the test, even while you are pressing it with your finger.
Press the Read button and read the moisture content on the display. The
meter will display the %MC (percent moisture content value) for two
seconds. Readings below 6% seed cotton will be displayed as a negative
number. Readings above 20% seed cotton will be displayed as a blinking
20.2%. Both the extreme low and extreme high readings should be
disregarded. They will not be added to the accumulated readings or used in
calculation of the average or highest readings.

OPERATION 7
Tests made on seed cotton may not be as accurate as those made on lint
cotton. This is due to the fact that the seed cotton sample is obviously made
up of lint and seed, and the quantity of seed may vary from sample to
sample. Also, the moisture content of the seed is usually higher than that of
the lint.
When testing seed cotton, direct contact is still made with the cotton fiber
only and not with the seed of the sample. Variables in quantities and
moisture content of the seed, during calibration and in field tests, may affect
the accuracy and repeatability of the meter readings. The seed cotton scale
gives an indication of total moisture content (the moisture content of the
seed and the lint in a sample as determined by oven tests) in the seed
cotton sample. This may be of interest only in buying and selling seed
cotton where some consideration may be given to the weight relationship
between moisture content and dry matter.
TESTING BALED COTTON
Slide the plastic spacer over the 467912010 contact pins from the bottom of
the pins. Mount the pins in the chucks and tighten the set screws. (The
467912010 contact pins are not inserted into the chucks for shipping
purposes.)
Attach the Type 467912010 Electrode to the connector on top of the meter.
Set the scale to LINT COTTON and select a set-point. Insert the electrode
pins into the bale and press the Read button. Place the pin spacers near
the tips of the pins when contact is first made with the bale. This helps to
keep the pins parallel as they are forced into the bale.
The 467912010 contact pins are insulated, except for 1-3/4” at the tip. The
insulation helps to identify the area of moisture, since the reading is
obtained from the tip of the pin. Keeping track of moisture readings as the
pins are pushed into the bale will give an idea of the uniformity of moisture
distribution in the bale. Higher moisture readings near the surface are an
indication that the cotton has been exposed to higher moisture after baling.
The Dj C-2000 provides accurate results on normally compressed bales. If
the bale is loosely packed, the meter will read lower than the actual
moisture content. If the bale is very tightly packed, the readings will be only
slightly higher than normal, and as a rule, no correction needs to be made.
Well-conditioned material will provide uniform readings. However, material
that is baled before it is dry will show a wide range of moisture content.
Several tests should be performed on each bale, and the average and
highest readings should be noted.
TESTING YARN
Connect the 467912020 Multi-Pin Electrode to the connector on top of the
meter. Set the scale to LINT COTTON and select a set-point. Insert the
electrode pins into the yarn and press the Read button.

FACTORS AFFECTING READINGS 9
FACTORS AFFECTING READINGS
Moisture content of the samples is the primary factor affecting meter
readings. However, readings are also affected by the following:
• Type of cotton.
• Area where it is grown.
• Impurities.
• Compaction (density) around the electrode surfaces.
• Temperature of the sample.
In order to minimize the effect of these factors and improve the repeatability
of the meter readings, it is recommended to keep in mind the following
points:
• Use samples with minimum of impurities.
• Optimal accuracy may be obtained it meter readings are checked
against %MC (percent moisture content value) by means of a properly
run oven test on the particular product being tested.
TEMPERATURE CORRECTION
The basic calibration assumes the cotton temperature to be 70OF. For best
accuracy, apply a temperature correction if the cotton temperature is outside the
range of 60OF to 80OF. Make a correction of approximately 1.0% for every 20OF.
The meter will read higher than the actual moisture content as cotton temperature
increases, and will read lower as cotton temperature decreases.
Example:
At 70OF, a reading of 7% indicates actual %MC (percent moisture content value) of
7%. At varied temperatures, meter readings will vary as follows:
Cotton temperature = 110OF Meter reading = 9.0% Actual %MC = 7%
Cotton temperature = 50OF Meter reading = 6.0% Actual %MC = 7%
