4.1 SAMPLE COLLECTION
The moisture content in various portions of a lot or parcel of grain to
be tested may vary considerably.
In order for the sample to be representative, grain should be removed
from different sections of the lot and thoroughly mixed. For the most
accurate results, a grain probe should be used and the sub-samples
mixed and divided in a Boerner divider.
If such equipment is not available, an equivalent procedure should be
devised and followed. The importance of accurate sampling cannot
be over stressed. This is true no matter what method of moisture
determination is used. In addition, the size of the sample upon which
the test is made should be as large as possible in order to average out
small variations. This is accomplished in the Seedburo Model

D
Digital Moisture Meter by the use of 3½” test cell which, for
most types of commodities, can contain sizes up to 300 grams.
The proper sample size is shown on the display. An outside scale
with the accuracy of .5 grams should be used.
4.2 POWER-UP
At Power-Up the Seedburo logo is shown on the screen, as well as the
program version and calibration version.
The Empty Grain cell and the empty DUMP cell must be connected to
the unit so that the instrument can perform the initial SELFTEST and
verify that all components are properly working.
Once the self test is performed (no error messages) the instrument
will change to the menu screen.
