This is a dual zero and spancalibration procedure.
Must bring sensor to NULLposition before calibrating.
This calibration technique allows youto independently trim the span settingwithout altering zero position.
Note, when trimming the span value,the zero offset value is automaticallyrecalculated and adjusted for the newscale factor.
