Deadband
The Deadband prevents alarms from triggering excessively when the sensor measurement
vacillates around the trigger point.
With High Alarms, the measurement must fall below the High Alarm point minus the Deadband
before the High Alarm will be triggered again. Likewise, the Deadband on the Low Alarm requires
the measurement to rise above the Low Alarm point plus the deadband before the Low Alarm will be
triggered again.
For example, if the deadband is set to 5, and a high alarm occurs at 50, the alarm will not trigger
again until the value first drops below 45 (50 - 5), as shown in the figure below. The default
Deadband is
0.50
.
