5-2 OSU 300 User Manual 61200663L1-1
All statistical information is given in screens based on the following
time periods: the current 15-minute interval, a 24-hour history
(divided into 96 15-minute intervals), and the totals for the
previous 24 hours. Also, a cumulative alarm count is given. This
count continues indefinitely until reset by the user.
Alarm History
The OSU 300 keeps track of yellow and red alarms for the near end.
View alarm history information in one of the three time period
selections, or view a cumulative alarm count. Information in these
fields is for the given time period (if any) since the last reset. The
cumulative alarm count continues indefinitely until

examples of alarm history screens.
An alarm history is also available for the individual ports of a Quad
