Alm Hysteresis - This field displays the alarm hysteresis (or deadband) value for the AI alarms in percent of Out scale. Click this value to enter a new value. An alarm does not recur until the PV has backed away from the corresponding limit by at least the percent of Out Scale specified by this value.
