3.4 Creating an ERROR Log
Use the ERROR submenu to create a new error log and to select the logging parameters. An error log updates every 5
seconds (when the display updates), but only if a new error condition occurs. Error logs have a fixed length of 2 pages
and contain sixty records per page. Each record shows the time of the error, the measurement parameter values at
that time, and the error code message. The logged values of the chosen measurement parameters at the time of the
error condition provide valuable troubleshooting information.
Press the appropriate side of the [SCREEN] key to activate the desired pane of the display screen, and complete the
following steps:
1. To access the Log Menu, press [LOG].
a.
If you have activated the security feature (see Chapter 1, Programming Site Data, page 50 for details), enter the
assigned password and press
[ENT].
2. Press [F4] = ERROR.
3. Use the [
, [ and [F1]-[F4] keys to inspect a completed log or to change an active log, or enter a new Name
(up to 5 characters) and press [ENT] to create a new log file.
Note: The option bar lists all error logs currently stored in memory. Recall that a flashing asterisk (*) appears at
the far right of the locator bar if the Model DF868 is currently logging data (see Chapter 3, Operation, page
3-4 of the Startup Guide).
4. At the Log Message prompt, enter a brief description (up to 21 characters) of the log and press [ENT].
5. Use the [
, [ and [F1]-[F4] keys to select the first parameter to be logged. See Table 36 for a list of the
available options.
IMPORTANT: Only the first
parameter logged may be graphically displayed (see page 63).
