30. uching takes place in a given teaching measurement time after teaching starts a teaching error is assumed and no parameter update takes place However when this value is 0 only the reference value REFx is taught In this case no teaching error is assumed because no touch is required A value from O to 255 can be specified Judging Change THRx The change approximate value of measurement at electrode touch is defined This parameter must be defined beforehand to differentiate measurement change due to noise noise change from change due to electrode touch At teaching touch is determined when a detected change is a half of the value defined here Accordingly the value defined here may be an approximate value at which the measurement may change at electrode touch 15 Hysteresis HYSx A hysteresis approximate value is defined A value of 0 may be defined here when noise Is relatively low On J udging Ratio RTHRx Hysteresis Ratio RHYSx The ratio of judging change THRx or hysteresis HYSx compared to measurement change due to touch is defined A value from 0 to 15 can be defined Touch each electrode three times or more for teaching Next B6TS internally calculates the minimum value of change for each electrode minimum change Assuming that the minimum change is4 A the judging change and hysteresis are calculated as followed Updated result of judging change THRx 4 A x On judging ratio 16
