test and calibrate each instrument before it leaves the factory. Use of the
instrument in the field, however, is subject to environmental and
operating conditions beyond our control. DICKEY-john®disclaims all
liability for damages resulting from environmental and operating
conditions beyond our control and for any damages that might follow
incorrect results due to those environmental or operational conditions.

The operator is responsible for ensuring the results of the testing are as
accurate as possible by following approved maintenance procedures on
a regular basis, making sure the calibrations are up to date and the latest
version is being utilized, 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 precision instrument, optimal
results depend in part on proper cleaning and maintenance.
The GAC™2700-LF moisture tester is not approved by the National Type
Evaluation Program (NTEP) for use in commercial grain transactions.
For questions concerning these issues, refer to the product warranty,
or call your DICKEY-john®representative.
The complete Operator’s Manual is available on our website.

Setting up the GAC™2700
Moisture Tester
Setting up the GAC™2700 moisture tester requires the
following procedures:
1. Open the carton and remove the Allen wrench from the upper
foam insert.
2. Remove the GAC™2700 unit from the plastic bag. Save the bag,
the packaging material, and the carton to use for future transport
of the instrument.
3. Ensure the installation location is level using the bubble level at
the top of the instrument; adjust the feet if necessary. Unit must
be kept level, making sure that there is sufficient clearance between
the GAC 2700 unit and the countertop so that the grain drawer is
cleanly inserted into the instrument.
4. Remove the grain drawer and place the unit gently on backside to
locate the shipping brackets on the left and right-side walls.
IMPORTANT:Be careful when placing the unit on its backside to
avoid damage to the security switch.
5. Loosen and then remove the hex bolt from the bracket on the
left side wall.

Maintenance
The GAC™2700 moisture tester utilizes an RF frequency of 149 MHz
to make measurements within the machine. It is not a strong signal
strength. If potential interference is determined to originate from the
GAC™2700 moisture tester simple corrective steps can be taken; move
the products further apart from each other, re-orientate the products to
each other.
IMPORTANT
It is highly recommended the unit be regularly inspected and
cleaned to ensure continued and consistent results.
For optimum performance, extensive cleaning should be
performed weekly or more often, as needed, based on
surrounding environmental 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.
For customers that require a more extensive cleaning, contact
and schedule your instrument for cleaning with your dealer or
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™2700 moisture tester’s surface can be cleaned with any
cleaner designed for plastic and stainless-steel surfaces.
