Test Procedure – Grain
1. Select a representative sample of grain to be tested.
2. Fill clean grain tray with grain. Compact sample by lightly patting and
smooth off level with top.
3. Insert the full tray into the test chamber and center the tray in the
chamber.
4. Apply pressure to the sample by turning the control know clockwise
until the yellow indicator band appears and the lower edge is level
with the knob face.
5. Press the "BATTERY" button to confirm that the battery voltage is
within the working limits. The digital display must read more than
75.0 (7.5 volts) or the battery should be replaced.
6. Press "SAMPLE" button and note log reading from the digital display.
7. Unwind the pressure knob and remove the sample tray. Check the
temperature of the sample using the tester's thermometer.
8. Refer to the temperature correction table for grains on the log charts.
Apply the temperature correction factor to the log reading according
to the chart. IMPORTANT: APPLY TEMPERATURE CORRECTION
TO LOG READING BEFORE LOOKING UP MOISTURE %.
9. Refer to the appropriate log chart of the grain under test and read
moisture content against CORRECTED log reading.
NOTES:
1. Keep hands away from ends of tet chamber when taking read-
ings, and never place tester on a metal surface when testing or
false readings will result.
2. If the sample of grain is to be held for even a short period before
being tested for moisture content, the grain should be placed in
a tightly closed, air-tight container, such as a zip-lock plastic bag
or a jar.
3. Variations between readings from your 1210 and your local
elevator are inevitable and normal. (Readings from two or more
elevators will vary.) We recommend that you take samples of
grain at different moisture levels to your elevator and note any
variations between your 1210 and your elevator's readings.
Apply these variations as a correction factor to the appropriate
log charts.
