Operation

OPERATING CONDITIONS

Test cell and grain MUST be free of any con-
densation 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 bot-
tom 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 oc-
cur. To enhance accuracy, always take three
(3) successive readings of the total sample
being tested and average the results. Empty
and refi ll 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 5. 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 plastic bag or jar.
