Operation

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.
