Alarm Interval
For high/low limit on rate-of-change alarms, variation is measured over a preset interval.
If the variation exceeds the preset value, an alarm occurs. This interval can be set and
applied to all channels.
Hysteresis
Set the width between the value of alarm occurrence and its release. This setting
prevents frequent alarm occurrences/releases in an unstable environment. Hysteresis
values can be set in the 0–1% percentage range of the span. The hysteresis setting is
used for high and low limit alarms.
Set the span percentage using the Alarm Hysteresis pull-down box.
