OPERATING CONDITIONS
Test cell and corn MUST be free of any condensa-
tion or surface moisture. Moisture on corn or in test
cell will cause high readings. Very hot or cool corn
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 corn is irregularly shaped and may not
always pack the same way in the test cell, minor
variations in readings may occur. To enhance ac-
curacy, always take three (3) successive readings
of the total sample being tested and average the
results. Empty and refill the tester with new corn
from the sample between each test.
The tester is most accurate when corn 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, corn temperature should not be below 40˚F (4˚C) or above 110˚F (43˚C). If the
corn 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 corn at about the sample temperature.

Operation

TO ADJUST CALIBRATION
IMPORTANT: Always obtain three (3) test
results from the grain elevator for the sample be-
ing compared. Average these three (3)
results. Compare this average with the
average of three (3) tests by the
moisture tester.
1. The corn scale can be individually adjusted up
to 5.0% by increments of 0.1% to more closely
match the results of an elevator tester.
2. Test the corn selected, using the sample you
wish to adjust to. Once valid moisture
appears, press the CAL button (A).
NOTE: Calibration of corn cannot be performed unless a valid
moisture test has been performed.
3. Once CAL button (A) is pressed, tester will now display the obtained moisture
reading and the current offset applied to that moisture range.
4. Press the UP arrow (B) to raise the adjustment amount or press the DOWN arrow
(C) to lower. The tester will add or subtract up to 5.0% by increments of 0.1% to
the current moisture range.
5. After the adjustment amount has been selected, press the CAL button (A) to return
to corn tester mode.
NOTE: Adjustment can NOT be made to factory calibration to produce
moisture readings in a tester that shows “LESS THAN 5%” or
“TOO WET” readings.
IMPORTANT: This tester incorporates single-point calibration for corn. Therefore,
once a valid test is taken and an adjustment is made, the adjustment will only affect
the moisture range of the sample tested.

CONDICIONES DE MANEJO
El medidor de célula y maiz DEBE estar libre de
cualquier condensación o humedad superficial.
Humedad en el maiz o en el medidor de célula cau-
sará lecturas de idas y venidas. El maiz muy caliente
o frío absorberá humedad cuando se caliente o
refresque. La funda de presión del medidor puede
exprimir humedad de granos altamente humedeci-
dos, como una mazorca, en el fondo del medidor de
célula.
Porqué los maiz son de forma irregular y no siempre
encajan por igual en el medidor de célula, variac-
iones en la lectura de menor importancia pueden
ocurrir. Para aumentar la precisión siempre tome
tres (3) lecturas sucesivas de la muestra total
aprobada y tomar un promedio. Vaciar y rellenar
el medidor con un nuevo maiz de la muestra entre
cada prueba.
El medidor es más exacto cuando el grano y el medidor están entre 60˚F (16˚C) y
90˚F (32˚C). La unidad sin embargo, funcionará con temperaturas entre 33˚F (1˚C) y
120˚F (49˚C). Para obtener mejores resultados, la temperatura del maiz no debe estar
por debajo de 40˚F (4˚C) o sobre 110˚F (43˚C). Si la temperatura del maiz es 20˚F (11˚C)
más o menos que la temperatura de la unidad, precalentar el medidor según instruc-
ciones en la pagina 5. Condensación en el maiz o medidor de célula es mejor evitarse
teniendo el medidor y el maiz con temperaturas casi iguales.
