TEST PROCEDURE – GRAIN
1. Select a representative sample of grain to be tested.
2. Fill clean grain tray with grain. Compact the 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 knob 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 test chamber when taking readings,
and never place tester on a metal surface when testing or false read-
ings will result.
2. If the sample of grain is to be held for even a short period before be-
ing 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 eleva-
tor 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 cor-
rection factor to the appropriate log charts.
