SAFETY NOTICES
Safety notices are one of the primary ways to call attention to potential
hazards.!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 avoided, 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,

INTRODUCTION
The DICKEY-john Grain Analysis Computer GAC500XT™quickly tests
grain and automatically calculates moisture content, temperature, and
approximate test weight (density) of the sample. The unit measures empty
cell characteristics, prompts for sample loading, tests the sample, and
displays the results. The selected grain name is also displayed during the
measurement sequence.
TESTING SAMPLES (QUICK START)
Performing a grain sample analysis consists of six basic steps.
1.
2.
3.
4.
Press the MEASURE function using the Arrow buttons
Press the Enter button to initiate a measurement sequence.
Follow display instructions to empty the cell
Press the Enter button to initiate empty cell measurements. A
progress bar will indicate measurement status.
5. Fill the hopper, strike the grain using the grain loader/striker (refer to
Figure 16), and press the Enter button to initiate grain measurement.
Again, a progress bar will indicate measurement status.
6. Read the test results on the display. Results include moisture,
temperature, and test weight.

SPECIFICATIONS
• Supply voltage and frequency
– wall mount adapter: 90VAC to 264 VAC, 47 to 63 Hz, 0.4A max
– 6-Volt vehicle adapter: 12-24VDC.
Operating temperature range: 5°C to 45°C (41°F to 113°F). If the
temperature range is exceeded, the until will measure moisture and
display an error message warning the operator that the readings do not
necessarily meet unit specifications.
Grain temperature range: 0°C to 50°C (32°F to 122°F). If the
temperature range is exceeded, the unit will measure moisture and
display an error message warning the operator that the readings do not
necessarily meet unit specifications.
Unit-grain temperature difference limit: the maximum allowable
difference between the empty cell and grain temperature is 20°C
(36°F). If the temperature range is exceeded, the unit will measure
moisture and display an error message warning the operator that the
readings do not necessarily meet unit specifications.
Classes/types of grain or seed: calibration bulletins may be obtained
through the DICKEY-john website (www.dickey-john.com) or by
requesting a calibration bulletin at:

OPERATOR’S MANUAL
INSTALLATION AND SETUP
Before shipping, the GAC500XT is tested and inspected to ensure the unit
is fully operational and meets all measurement specifications. After
unpacking, inspect for damage that may have occurred during transit. Save
all packing material until inspection is complete. If damage is found,
immediately file a claim with the carrier. Also notify your DICKEY-john Sales
Representative.
NOTE: Before relocating or
shipping the GAC500XT,
the shipping screws must
be replaced.
REMOVING SHIPPING SCREWS
Once the GAC500XT is placed in a level location, remove the shipping
screws.
Make sure shipping screws are removed prior to operating the
GAC500XT. Failure to do so may permanently damage the unit.

UNIT POSITIONING
To achieve the most precise measurements, select a location that is clean,
level, and protected from rapid changes in temperature. Level installation
helps to ensure weight measurement that correlates with the GAC2100.
