- Set the input current to 0% (4mADC in the standard specification) and turn the zero adjusting knob by hand to set it to the actuator starting point.
- Then set the input current to 100% (20mADC in the standard specification) and check the actuator stroke. At this point depending on the span is too large or too small, loosen the lock screw and adjust the span as shown in the illustration above.
- Set the input current to 0% and conduct the zero point adjudtment, as done in Step (1) again.
- Repeat the above operations until the predetermined stroke of the actuator is obtained to the input current.
