AUTO3 Calibration Mode:
AUTO3 will only change the valve parameters. Zero and End Point adjustments will not be made.
Manual Mode:
MANUAL mode is used to adjust the valves stems movement manually. In MANUAL mode the positioner will bypass
the supply pressure to the actuator. The valve stems movement in this mode will not affect the positioners save data
values.
PARAM – Parameter Mode:
While AUTOCAL optimizes the actuator values, in some applications where hunting or oscillation occurs it may be
necessary to make additional adjustments in PARAM mode.
Once the parameter values have been adjusted, the new values are saved as soon as they are adjusted. There
is no need to return to RUN mode after changes are made to observe the changes.
