While specifically for the 3560, you may need to look for or similar documentation from Emerson Process Management.
Increase the input signal to the maximum value (e.g., 15 psig).
Ensure the process line is completely depressurized and bypassed if necessary. Disconnect all power and air supplies to the actuator.
Repeat the zero and span adjustments iteratively until both endpoints are accurate. Fisher 3560 Valve Positioner Manual Pdf
Observe the valve travel. If the valve does not reach full travel, or reaches it too early, you must adjust the span.
Let us apply what we have learned. With the open to page 18 (Calibration Procedure), follow this simplified process:
Dependent on the specific model and actuator requirements, typically up to 100 psig (6.9 bar). 2. Fisher 3560 Model Variations While specifically for the 3560, you may need

The Ultimate Guide to the Fisher 3560 Valve Positioner: Manual, Operation, and Maintenance
Increase the input signal to its maximum value (e.g., 20 mA or 15/30 psi). Disconnect all power and air supplies to the actuator
The input signal pressure acts upon the instrument bellows.
is to ensure the valve stem position precisely matches the control signal by continuously adjusting pneumatic output to the actuator.
The Fisher 3560 series (specifically the ) is a legacy pneumatic valve positioner typically used with sliding-stem actuators. Because this is an older model, technical documentation is often found in consolidated Fisher manuals or archives from Emerson . Quick Reference Guide
