Recording in the Event Log
The Event Log is a table that displays events recorded by the unit. A scroll bar is
available, allowing you to scroll up and down to view an extended history.
To use the Event Log:
1. Select a protocol processor tab.
2. Select the
Results button.
3. Select Event . As events occur (such as alarms, errors, or Pointer activity) they
appear and continuously scroll in the table.
Events display in a ascending order from the most recent event to the oldest
event. The Descending button indicates that events appear in descending order.
(This button switches between descending event order appearance and
ascending event order appearance. The current label of the button indicates the
event order.)
4. To begin a new test, select the Restart function button located at the bottom of
the touch screen. This will clear all history of previous events, and resets the
Start Test Date and Time stamp to current time. You now have a reference
point as to when new events occur, in comparison to when the test began.
5. Select Pause , to stop the scrolling action and then use the scroll bar to view
events. Select Resume to restart the event log.
