(C70) Span adjustment
Zero point / span for a positioner can be adjusted. PID constant
will not be set unlike automatic calibration (parameter code: C30).
This adjustment is useful when zero point / span needs to be
adjusted again with the PID constant set before.

(C80) Initialize
Initialize (parameter code: C80) is used for mounting the
positioner, which is mounted to the actuator and calibrated, to
another actuator, or returning parameter set values to ex-factory
condition. After execution, calibration is necessary to return to
ex-factory condition.
16: If operation direction is changed by exchanging piping of OUT1 and
2 with each other after calibration, calibrate a positioner again.
17: See "■Improved Controllability" if hunting with a PID constant set
by calibration needs to be performed.
18: After execution, all parameters returns to ex-factory condition. Can
not return to condition before execution. When parameters changed
manually before execution is necessary, take notes of them
beforehand.
