Could someone explain it simply? I’ve searched for some answers, but I still don’t understand

Normally, when PV ≤ 1 MPa, the alarm should be cleared; however, sometimes the process isn’t yet stable, and PV keeps fluctuating around 1 MPa, causing the alarm system to continue issuing alerts. To prevent such a situation, the threshold for exiting the system alarm state is set at 1 range * 2% (it can also be set to 2%-5%) MPa, that is, 0.97 MPa; this means that when PV
