Custom Split Range End (CST ENd)
It is used to set the current corresponding to the endpoint when the valve position of 0 to 100 % is
controlled by the user-set CUSTOM. For example, if the valve is controlled by 4 ~ 18 mA instead of 4
~ 20 mA, CST END is 18 mA. However, the difference of the current between the origin point and the
endpoint must be greater than 4 mA.
