12.1 General
12.2 Hysteresis error
Angular measurement errors by the KMA199E result from linearity errors, temperature
drift errors and hysteresis errors.
where the measured angle
curve will further be denoted as angle reference line
For valid definition of errors, the angular range is set to
voltages are programmed to V
The hysteresis error
the device output when performing a positive (clockwise) rotation and negative (counter
clockwise) rotation over an angular range of 180 , measured at a constant temperature.
