Q: How do I perform calibration?
A: Simply press the Auto-Calibration button — the positioner completes the process automatically in minutes.
Q: Can I customize the valve response curve?
A: Yes — select Linear, Quick Open, Equal Percentage, or create your own 5- or 18-point characterization.
Q: What is the typical air consumption?
A: Less than 2 LPM at idle, helping plants achieve significant energy savings.
