Creating an ERROR Log

Logging Data
ERROR
Use the 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.
