Alarms Log Page
A maximum of 40 High/Low alarms, along with date and time of occurrence, are
recorded in a ring buffer in NV memory. The most recent alarm will overwrite the oldest
alarm when more than 40 alarms are recorded. The data is displayed over a maximum
of 10 pages (with 4 alarms on each page). The latest alarm record is displayed in line
1 of page 1. This data is not available via serial communications or in the blind unit.
The data is reset manually via the Reset Page in the User Menu. The data is saved and
restored when the instrument is restarted. P1 = Page 1.
