OPERATING CONDITIONS
Test cell and grain MUST be free of any condensation
or surface moisture. Moisture on grain or in test
cell will cause high readings. Very hot or cool grain
will pick up moisture when it warms or cools. The
pressure cap of the tester can squeeze moisture from
high moisture grains, such as corn, into the bottom of
the test cell.
Because grains are irregularly shaped and may
not always pack the same way in the test cell,
minor variations in readings may occur. To enhance
accuracy, always take three (3) successive readings
of the total sample being tested and average the
results. Empty and refill the tester with new grain from
the sample between each test.
The tester is most accurate when grain and tester are between 60˚F (16˚C) and
90˚F (32˚C). The unit will, however, operate at temperatures between 33˚F (1˚C)
and 120˚F (49˚C). For best results, grain temperature should not be below 40˚F
(4˚C) or above 110˚F (43˚C). If the grain temperature is 20˚F (11˚C) more or less
than the temperature of the unit, preheat the tester per instructions on page 10-4.
Condensation on the grain or test cell is best avoided by having the tester and
grain at about the sample temperature.
The environment to which a grain sample is exposed can appreciably change
its moisture content. Exposed to the open air, grain can gain or lose 1% to 2%
indicated moisture in only a few minutes. If a sample is to be held for even a
short time before being tested, it should be placed into a tightly closed, air-tight
container, such as a re-closable bag or jar.

TESTING GRAINS THAT ARE ABOVE OR BELOW THE LIMITS
If the grain being tested in the tester is above or below the grains calibration
limits the tester will display a < (less than) or > (greater than) symbol followed
by the tested grain’s upper or lower moisture limit. Even though the tester can’t
display a valid moisture result this information is still useful because you still
know the range above or below that the tester can display.
NOTE: Grains that are above or below the limits are not stored for averaging.
DISPLAYING THE AVERAGED MOISTURE RESULTS
1. Each time a moisture test is taken the averaged moisture result is
automatically displayed along with the current moisture and temperature.

Operation
CALIBRATION CONSIDERATION / LIMITS
Typically the moisture tester will be consistent
with most elevator testers over a broad range
of moisture levels. However, there are some
things to consider when thinking about your
moisture tester calibration.
NOTE: Graph 1 provided is for illustration purposes
only and does not reflect actual test data.
1. Tester Differences: Your moisture tester
unit may not match a given elevator tester.
None of the testers exactly match the
actual weighted moisture of any given
grain. There is no national standard for
elevator testers. The difference between
moisture testers and various U.S.D.A.
approved elevator testers is not a constant
value. A correction at one moisture level may
not be valid for a different moisture level.
Graph 1 illustrates how the moisture tester
might compare to an elevator tester over a
broad range of moisture levels. The moisture tester and most elevator testers
(shown in graph by solid line) will closely match those of the moisture tester
(shown by dashed line) for that range, as illustrated. However, as we get away
from mid-range into the high and low moisture levels, differences between
elevator tester and moisture tester not only become greater, but may switch
from a moisture tester reading higher than elevator tester to a reading lower
than the elevator tester. For example, in Graph 1, the area between B and C
represents the mid-range moisture. Moisture tester readings match elevator
tester readings in this area with an accuracy of plus or minus 0.5 percent.
The area between A and B represents the low moisture range. Moisture
tester readings differ more from elevator tester readings, and are LOWER
than elevator tester readings. The area between C and D represents the
high moisture range. Moisture tester readings again differ more from elevator
tester readings than they did at mid-range moisture, but now the readings are
HIGHER than elevator tester readings.
2. Calibration Requirements: Graph 1 illustrates that moisture tester readings
closely match elevator tester readings for mid-range moisture levels. (Graph
1 is for illustration purposes only and does not reflect actual test data.)
Calibration changes required for grain in this moisture range will be small,
if any. However, if grain is very dry (Low Moisture Range) or very wet (High
Moisture Range), it may be necessary to calibrate your moisture tester unit
against the elevator tester using a sample of your grain in both testers. Record
the calibration correction required. It will be valid for all testing in that moisture
range for that grain.

LOW MID HIGH

SYMPTOM A: Unit does not power up or loses power
occasionally (or backlighting does not operate.)
SOLUTION 1: Press ON-OFF button for shorter time.
Do NOT hold button down.
SOLUTION 2: Check batteries for 0% or higher.
Replace as necessary.
SOLUTION 3: Battery contacts may be making poor
contact. Remove batteries and pull metal contacts (A)
up from bottom of compartment and above height of
plastic knob using needle-nose pliers.
SYMPTOM B: Unit is inaccurate.
SOLUTION 1: Temperature of the grain and unit may be more than 20˚F (11˚C)
different. Follow preheat procedure (See page 10-4).
SOLUTION 2: If grain is at an extreme temperature, let grain settle to reach room
temperature. Retest grain.
SOLUTION 3: Grain and/or test cell may have developed surface moisture from
rapid change in temperature of the grain sample. Allow grain and tester to stabi-
lize near room temperature. Inspect for visible moisture on grain and inside test
cell. Dry the test cell with a soft cloth or a blow dryer if necessary. Retest grain.
(See page 10-5).
SOLUTION 4: If the tester displays SYSTEM BATTERY LOW, the test results
may be inaccurate. Replace battery.
SOLUTION 5: Unit may need to be re-calibrated by factory. Return to your John
Deere Dealer for repair or replacement.
SYMPTOM C: Unit reads MOISTURE BELOW LIMIT or MOISTURE ABOVE LIMIT.
SOLUTION 1: Grain may be too wet or dry to test. Check moisture limit guide-
lines on page 10-6 of Operating Instructions. NOTE: Limits shown on page 10-6
are only guidelines.
SYMPTOM D: Unit reads ERROR (---).
SOLUTION 1: Electronic failure. Return to your Dealer for repair or replacement
or contact manufacturer (See page 25-1).
