EVENT LOG SCREEN

Displays the last 2000 events logged in the ST-72. The events are logged in a first in first
out format, in non-volatile memory so a SD card is not necessary to view the event log.
These events include Alarms In and Out, Alarm Resets, Calibrations, System and Cold
Boots, and Communication and Configuration Error. The events are time and date
stamped and if channel specific the number is shown in the right column in Figure 8-4.
