2.5.6.5. Limit Hysteresis
Hysteresis is used to adjust the sensitivity of the trigger for alarm
messages. It is used to compensate when a process variable fluctuates
around the same value as a limit. A high level alarm occurs when a value
exceeds an upper limit. The alarm’s status remains true until the value
drops below the limit minus the alarm hysteresis. The directions are
reversed for low limit detection.
Enter a value for the hysteresis here, to be used for all warnings and
alarms. The units are always %.
