Accessing the Review
Errors Menu Option Item To access the error log and learn more about the REVIEW ERRORS
menu option item, follow these steps:
1. Rotate and press the Trim Knob control to scroll to and select
REVIEW ERRORS from the service mode menu option items.
2. The review errors menu option items include four possible selections;
one each for viewing output or input errors along with one each for
clearing output or input errors. Rotate and press the Trim Knob
control to scroll to and select VIEW OUTPUT ERRORS from the
review errors menu option items.
3. The RUN TIME ERROR LOG pop-up window appears on the left
side of the monitor display. One time-dated output software error
appears in the pop-up window at a time.
The Trim Knob control can be used to scroll through each logged
error, perusing all of the parameters associated with each output
software error. Rotate the Trim Knob control to move the cursor ( > )
to a position for viewing the NEXT or PREVIOUS error as well as the
position that allows the user to QUIT viewing output errors.
Selecting QUIT closes the run time error log pop-up window and
returns to the review errors menu option items.
4. The VIEW INPUT ERRORS menu option item, when selected using
the Trim Knob, causes a RUN TIME ERROR LOG pop-up window to
appear on the monitor display. The pop-up window now displays
input software errors and provides basically the same information as
the VIEW OUTPUT ERRORS pop-up window provided. The
appearance of both pop-up windows are similar, the difference being
errors that are logged as input versus output to/from the monitor.
5. To clear out the stored run time error logs, use the Trim Knob to
scroll to and select the CLEAR OUTPUT ERRORS or CLEAR INPUT
ERRORS menu option item, respectively.
Immediately following the assertion of the Trim Knob to clear one of
the error logs, a message appears directly above the menu option
items, on the right side of the display. The message verifies the
actuation of the Trim Knob for this function.
Error Log
Information
This part of the section describes in greater detail what information the
error log contains and what can be learned from error logs.
An error log in the monitor is constructed as a circular file (not referring
to a wastepaper basket). This circular file can hold up to 50 events. As an
event occurs, error information is stored in the log. Subsequent events
are stored sequentially as they occur. When the 50-event limit is reached,
the next error (the 51st error) is written over the first event that was
logged, erasing that event and replacing it with the latest event. The
52nd event is written over the second event, and so on. If errors occur
infrequently the error log could span a period of weeks and months,
maybe even years. For example; if a problem with the network begins,
repeating frequently, the error log might consist only of errors from the
last few hours. In any case the error log contains the 50 most recent
detected and recorded errors.
