This table contains the dead band values for set point adjustment at 10% and 90% of the selected scale. For adjustable dead band the lower value corresponds to the dead band spring totally released and the higher corresponds to the dead band spring fully tensed . For other set points the dead band value can be calculated by linear interpolation between the values at 10% and 90%. Design and specifications subject to change without notice Scale P.
