Safety notices are one of the primary ways to call attention to potential
hazards. An absence of specific alerts does not mean that there are no
safety risks involved.
This Safety Alert Symbol identifies important safety
messages in this manual. When you see this symbol,
carefully read the message that follows. Be alert to
the possibility of personal injury or death.
Use of the word WARNING indicates a potentially hazardous
situation which, if not avoided, could result in death or serious
injury.
Use of the word CAUTION with the Safety Alert Symbol indicates a
potentially hazardous situation which, if not avoid ed, may result in
minor or moderate injury.
Use of the word CAUTION without the safety alert symbol
indicates a potentially hazardous situation which, if not avoided,
may result in equipment damage.

SAFETY NOTICES/1
OPERATOR’S MANUAL
LIABILITY
DICKEY-john designed the GAC® 2500 to measure oilseed and grain
moisture content. We rigorously test and calibra te each instrument before it
leaves the factory. Use of the instrument in the field, however, is subj ect to
environmental and operating conditions beyond our control. As a result, we
are unable to take responsibility for those conditions and any damages that
might follow incorrect results due to those environmental or operational
conditions.
Therefore, we expect the operator to take responsibility to assure that the
results of the testing is as accurate as possible by following approved
maintenance procedures on a regular basis, by cleaning the instrument and
its sensors on a regular and as-needed basis depending on the amount of
dust, dirt, and debris encountered in the instrument’s use, by monitoring
performance using daily check samples, and by adhering to the check
procedures set forth in the manual. As with any kind of sophisticated
equipment, optimal results depend in part on proper cleaning and
maintenance.
For questions concerning these issues, refer to the product warranty, or call
your DICKEY-john representative.

INTRODUCTION
The DICKEY-john Grain Analysis Computer GAC® 2500-AGRI quickly tests
grain and automatically calculates moisture content, temperature, and test
weight (bulk density) of the sample. The unit prompts for sample loading,
tests the sample, and displays the results.

OPERATOR’S MANUAL
INSTRUMENT PLACEMENT
Place the instrument in a clean environment that is protected from rapid
changes in ambient temperature and vibration. Avoid a hazardous
(classified) location as defined in Article 500 of the NFPA Handbook of the
National Electrical Code.
•Instrument should be placed on a flat, level surface that does NOT
exceed more than 1 degree of tilt (left to right and front to back).
CAUTION: A surface that exceeds this requirement can effect
measurement results.
•Surface should be vibration free.
CAUTION: Vibration from other machines or devices can
effect measurement results.
LEVELING INSTRUMENT
A bubble level located on the top surface of the instrument aids in leveling
the instrument for optimum test weight measurement.
– Adjust the feet (4) on instrument bottom until bubble is in the center
of the level.

MAINTENANCE
IMPORT ANT: It is highly recommended the unit be regularly ins pected
and cleaned to ensure continued and consistent result s.
For optimum performance, extensive cleaning should be performed
weekly or more often based on surrounding environment al conditions.
Factors such as dust, temperature extremes, grain dust, and external
humidity vary from location to location. If there are any questions
about the cleanliness or instrument performance, contact your local
authorized service center.
Note: The following recommendations are provided as a guideline to
maintain a robust and quality operating instrument. It should not be
interpreted as an exhaustive maintenance program. Dust and debris may
periodically accumulate in areas not specified in this manual. The owner is
responsible for ensuring overall equipment cleanliness. If any questions
arise regarding the maintenance or performance of the instrument, contact
your dealer or local authorized service center.
EXTERNAL CLEANING
The LCD display may require periodic cleaning. Use a commercial cleaner
for glass lenses to remove dust.
Do not apply water, organic solvent or chemicals, such as acid
and alkali to the LCD display.
The GAC® 2500 surface can be cleaned with any cleaner designed for
plastic and stainless steel surfaces.
Periodically use a rag to wipe the grain hopper and the (2) upper grain
hopper sensors.

INTERNAL CLEANING
Performing continuous tests can result in material accumulation a round th e
critical internal components and adversely affect the measurement.
Two types of cleaning are recommended on an as needed basis:
•Daily clean
•Extensive clean
DAILY CLEAN METHOD
A daily clean method allows cleaning the cell and door using an auto mated
process. During the cleaning sequence, the hopper door automatically
opens. Instruments with version 2.4 grain handler firmware, the trap door
opens automatically also.
To start the cleaning process:
1. At the Main Menu screen, press the Instrument Information button.
2. At the Instrument Information screen, press the Clean button.
– Pressing the Clean button automatically begins the cleaning
sequence and opens the hopper door and the trap door (versio n

EXTENSIVE CLEANING METHOD
NOTE: For customers that require a
more extensive cleaning
procedure with buildup in the
cell, contact and schedule your
instrument for cleaning with
your dealer or authorized
service center.
The daily cleaning method should be performed first before proceeding to
the extensive cleaning method .
IMPORTANT:
Extensive cleaning should be performed weekly or more often based
on surrounding environment conditions. Factors such as dust,
temperature extremes, grain dust, and external humidity vary from
location to location. If there are any questions about the cleanliness or
instrument performance, contact your local auth orized service center.
Tools required for internal mechanism cleaning:
•Brush p/n 206410003 (included with instrument)
Extensive cleaning of the instrument involves two steps to ensure optimum
instrument performance:
1. Internal mechanism cleaning
2. Temperature sensor probe cleaning
To Clean the Instrument:
1. Power down the instrument.

CLEANING THE TEMPERATURE SENSOR PROBE
IMPORTANT: Any particles in front of the sensor’s optics can affect
measurement performance. Therefore it is crucial to
sufficiently clean the sensor. For excessive dust and/or
foreign material buildup on or around the temperature
sensor, it is recommended the instrument be returned to
DICKEY-john Service or authorized service center.
The temperature sensor may require clea n ing due to du st bu ild up and/o r
foreign material that has collected around the sensor that could potentially
cause temperature error readings during analysis. It is important the
temperature sensor is visually inspected and cleaned each time a regular
maintenance check of the instrument is conducted.
Tools required for cleaning the temperature sensor probe:
1. One of the below cotton swabs:
– Standard 6” long cotton swab (i.e. McMaster-Carr p/n 7074T12) for

3. For instruments with the flush sensor and brush bracket, the following
procedure can be utilized to remove particles from the brush. Carefully
place the head of the screw driver (10” length recommended) at the
istles and use a sweeping side-to-side motion through the entire
