3.7.3. Events
The list of trips recorded by the protection release is available in the Measurements-Log Files-Events section.
The page of each event is similar to that of the trips, with a description of the event instead of the message about the protection
and numbering that refers to the last event recorded (Last, Last-1, Last-2,...).
PR332/P and PR333/P are able to record up to 80 events. Use the UP and DOWN buttons to scroll all the events.
3.7.4. Measurements Log register
PR332/P and PR333/P can record various different measurements and allow the recording time between one measurement and
the next to be set.
The measurements are available in the Measurements-Log Files-Measurements section:
