Setting Limits for a Phase-Tracking Fault Notification
Use this menu to have the detector give you a fault notification when the phase angle of
the product exceeds the default or user-defined “unacceptable change” notification limit.
Phase Tracking Fault Limit
In the example above, the current phase-angle setting is 90 degrees and the
“unacceptable change” notification limit is a change in phase angle plus or minus
10 degrees. Thus, if the most-recent value for phase angle is larger than 100 degrees or
smaller than 80 degrees, the detector will notify you that a fault has occurred.
Modifying the “Unacceptable Change” Limits
To modify the “unacceptable change” notification limits, do the following.
1)
Make sure the phase-tracking fault-limit function is highlighted (as shown above).
2)
Press the Go button and an input screen appears.

fault notification to occur.
