How can I determine the ON/OFF values of contacts “a” and “b” of an IS3000 series pneumatic pressure switch with a set pressure of 0.3 MPa?

According to the IS3000 specifications, the following can be said.
For hysteresis ± 0.05 MPa or less: “scale error ± 0.1 MPa” and “repeatability ± 0.05 MPa” are added to the ON/OFF values shown below.
Contact “a”: Turns from OFF to ON at 0 to 0.3 MPa.
Turns from ON to OFF at 0.5 to 0.4 to 0.3 to 0.25 MPa.
Contact “b”: Turns from ON to OFF at 0 to 0.3 MPa.
Turns from OFF to ON at 0.5 to 0.4 to 0.3 to 0.25 MPa.
