Two Factor Dispersion Analysis of the Capacitive Grain Moisture Meters' Transfer Function

Moisture content in many cases determines the consumer properties of different food products. The main task of the study was to analyze robustness for the two types of the transfer function for the capacitive grain moisture meter when working with different types of grain. To check the robustness of the transfer function, we applied dispersion analysis. For both transfer functions we can choose two factors: influence of moisture content, and influence of grain type, which is of a special interest. Besides, the values of repeatability and adequacy dispersions for both of the transfer functions were calculated. The values of the repeatability and adequacy dispersions for the newtransfer function were approximately three times smaller, and F-test values were seven times smaller, proving its' better workability.
