EJA variator

In the Hart menu of the EJA differential pressure transmitter, what do SP and SP H/L Select mean under the SP sensor option? Can the H/L in SP H/L Select also be modified?
You mean the content that should be in the picture
I’m not sure if they understood the diagram upstairs; it seems that it’s possible to change the direction of the positive and negative pressure chambers. This feature is mainly used when the positive and negative pressure chambers of an instrument are installed in the wrong order and it’s not feasible to modify the pressure transduction tubes. Nevertheless, this feature should be used as little as possible, as it can lead to misinterpretations if someone unfamiliar with the setup checks the instrument. Many instruments do not offer this feature, and although it may be convenient, it hinders proper operation and can result in errors
Thank you. I consulted Yokogawa, and they said that the range of static pressure being measured generally cannot be changed
