Appendix F Additional PDU Information
Default Hysteresis Values for Thresholds
Event Types
In This Chapter
Event Types...........................................................................................245
MAC Address ........................................................................................247
This table describes the default hysteresis values for each type of
measurement. Values must recede past the threshold by the hysteresis
value before the Dominion PX de-asserts the condition. You can disable
the hysteresis feature for outlet current while the feature for other
measurements continue to apply. Or you can change the default
hysteresis on appropriate threshold pages for each measurement.
