Chamber Calibration Overview
Calibrating the chamber to create a moisture curve consists of two parts:
1.
Calibrating with moisture and test weight with the first sample.
2.
Calibrating with the remaining moisture samples.
Both of these parts are necessary to create an accurate moisture curve.
To begin the calibration you will need one sample that is at least 6 lb (2.7 kg) at the
industry moisture standard (e.g., the industry moisture standard for corn is 15.5%).
For more information about the industry moisture standard, see
Moisture and Test
Weight.
Continue the calibration with a dry grain sample and a wet grain sample (more samples
can be used as well). Each sample should be cycled at least three times.
The Calibration Steps in the table below describe each step needed to create a moisture
curve.
