5. Close the discharge gate of the blanking cylinder, empty the sensor of the sample and prepare for the
next measurement.
6. In order to reduce measurement error, pay attention to the consistency in operating method: the same
sample (especially large-grain samples such as corn) shall be subject to several measurements, whose
results will be averaged: press the “
” key once and the average value of previous measurements
will be shown.

IV. Error Correction
Due to objective factors in regions and category difference, preset calibration parameters with the meter
shipment may have limitation and measurement error is likely to occur. The moisture value can be
corrected with the following method so as to guarantee or improve measuring precision:
1. Determine error correction value: as a rule, the moisture value measured through 105 standard
℃
drying oven method is adopted as the standard value. The correction value is obtained by deducting the
measured value from the standard value. For instance, the moisture value measured by the meter is
13.6%, but actual moisture value to be displayed is 14.0%. So correction value is +0.4, which means
that the calibration is 0.4 upward. If the correction value is negative, that means the downward
calibration is necessary;
2. Enter into correction status: take the sample out of the meter, press and hold the “Category” key and
release it after hearing the buzz. By this time, the character “Correction” flickers on the LCD panel,
which means the meter has been in correction status, and the set error correction value (the default
correction value before shipment is 0.0) is also displayed;
3. Correct error: press the “ ” key to raise the correction value (e.g.,
△
0.4), and then press the “
确
定
”(OK) key to save the value. The meter will flicker for confirmation. Turn off the meter or press the
“Category” key to exit from correction status.
The entire correction process is shown below:
