MCT466-QC User Guide Manual Linear Regression Statistics The NIR tester’s calibration program calculates several statistics during its calibration routine; these statistics give a measure of the accuracy and quality of the calibration. Correlation Coefficient: This is an expression of how well the tester readings match the true moisture values. - Page 19 Cooler Temperature: This is the actual detector’s temperature.

The miscellaneous menu, shown in Figure 23 below, provides access to change the password of the user menu and the readings decimal places. It also lists the MCT466-QC NIR tester’s information such as the sensor version, board type and the interface version. - Page 23 This submenu helps the user control the MCT466-QC signal’s gain for better performance. The Gain is also presented in the diagnostics menu to help balancing the MCT466-QC NIR tester. The pregain is a user selectable gain factor that is used to adjust the size of the reflected filter signals.
- Page 24 MCT466-QC User Guide Manual Signal Gain System The MCT has a software adjustable preamp gain factor. This factor is the gain applied to the filter signals coming from the detector. The amplification applied is split into two components: Pre-Gain: This is a manually settable course gain factor that selects a pre-amp gain resistor to amplify the detector signals.

Questions and answers
Hi, we have a model that has not been calibrated since 2022. I **** wondering how often it should be calibrated. As well, is the moisture in dry basis or wet basis?
The document mentions "Calibration Confirmation: Calibration Check Standard" during scheduled plant maintenance but does not specify an exact frequency for calibration. The moisture measurement can be in dry basis mode, as described, where moisture is calculated as a percentage of the dry material rather than the wet material.
