Due to mechanical tolerances and manufacturing differences in the potentiometer, it is difficult to predict the
degree of rotation of the potentiometer. Table 7 gives an orientation for the configuration of the QS3 voltage,
hence the radar's hold-time. Please note that your values may differ slightly from the values below.
