Extension of the Calibration Curve We have a theoretical curve for the WS in the PSB. Theory Curve Theory Curve Extension Linear Curve Extension We are in this region! 24 11/08/2014 Carolina Bianchini 18/11/2014
Extension of the Calibration Curve The extension procedure calculate all the steps between one point and the next one in the Theoretical curve. Then I have: -Theoretical curve (position vs potentiometer) -Theoretical curve steps. In order to add the extension, the program search the last point around 30 and -30 on the first array. Then with the same array-index, in the second array get the step-value and add on the last point. Following this operation with the others steps in order to arrive at 50 and -50. 30 -30 25 11/08/2014 Carolina Bianchini 18/11/2014
