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:
