Empty the bottom unit by turning it and
clean it by means of the paintbrushes
with hard or soft bristles depending on
the moisture content or the glueing of
the sample
.
Attention!
Do not beat out the lower part!
This can lead to damage the
measuring cell.
Notice:
For moist, oily and sticky samples we
recommend to grind a dry sample
(approx. 14
measuring cell.
Residuals are connected with the coarse
meal and can easily be removed.
6.4 Automatic temperature correction
The temperature correction is executed automatically. Reliable results are obtained at
ambient temperatures between 10 °C to 30 °C. For optimal results the instrument and the
sample to be tested should have nearly the same temperature. Warm grains just taken from
the drier should be measured after cooling down. Cold grain should be allowed to warm up
to ambient temperature, e. g. by spreading it out on a sheet metal.
6.5 Maize, especially humid maize, e. g. freshly harvested maize
For maize use a filling measure heaped with kernels. When changing from moist to very dry
samples, e. g. during drying we recommend to carry out a »blank test«. The measurement
takes place as with the normal measurement, but the result is not taken into consideration.
For this purpose fill the measuring cell, close it, open it and refill the measuring cell again
with the filling measure slightly heaped with maize, close it and only then carry out the
measurement.
6.6 Sunflower seeds
When testing sunflower seeds use a slightly heaped filling measure.
