① Mount the positioner to the control as shown below
② Connect the feedback lever to control valve stem at position where the angle between the valve stem and the feedback lever becomes 90˚ as shown below when the input signal is to 12mA (50%)
③ Stroke range for the best performance should be 5~80mm and the operating angle of the feedback lever should be maximum 45˚ to carry out accuracy perfectly |

① Mount the multi-tupe barcket to the actuator as shown below
② Confirm the rotating direction of the actuator for air piping (see catalog and manual for details)
③ Confirm if the feedback lever shaft "A" is placed in the orifice of the fork lever "B" and they are in perfect alignment with a rotary actuator output shaft |

① Supply 4mA input signal and set Zero by turning the zero screw on the control board until Zero reaches 0% of the valve / actuator
② Supply 20mA input signal and set Span by turning the span screw on the control board until Span reaches 100% of the valve / actuator |
|
 |
| |
 |
Input signal should be porvided for measurement of output signal.
① With a mA loop calibrator Select Measurement mode and connect ＋ to 4 and － to 5
② With a mulitimeter tester(mA) |
