Period T:
Period T indicates the positioners internal control time interval. By default the Mark 17X will check the current posi-
tion, respective to the current input signal every 100 msec.
Auto DZ (AUTO dZ):
After auto calibration, the positioner will automatically create deadzone. In some cases due to valve packing friction,
it may be necessary to increase the deadzone settings to reduce hunting or oscillation.
