Test cell and grain MUST be free of any conden
-

c

or cools. The

The tester is most accurate when grain and tester are between 60
˚
F
(

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
1
10˚F (43˚C). If the grain temperature is 20˚F (11˚C) more or less than the temper
a
-
ture 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

The environment to which a grain sample is exposed can appreciabl
y
change its
moisture content. Exposed to the open air,
g
rain can

ain or lose 1% to 2% indicated
moisture in onl
y
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

difference between moisture testers and various U.S.D.A. a
