8.6.1 Dead-Zone (dEAdZONE, %)
Dead-Zone indicates the percentage of error allowance. When AUTO 2 or AUTO 3 calibration are
done, this value would be set automatically and moderately. But if hunting still occur after AUTO 2 or
AUTO 3 calibration for the reason such as high level of packing friction, increasing the value of
Dead-Zone can stable the valve operation.

8.6.2 P1 Value (KP1)
P value indicates the ratio of the compensation signal based on the percentage of error allowance.
As the value increase, the positioner finds the target point quickly, but it is more likely to have hunting.
As the value decrease, the stability of the positioner is higher, but it finds the target point slowly. But
these values are applicable for only when input signal is increasing.
