Status Data – Diagnostics History 
This screen is only in instruments that have the Real Time Clock option and appears 
when you click on the “Diagnostics” button on the Status Data Maintenance Screen. The 
Diagnostic screen shows the last ten diagnostic conditions that have occurred. A blank in 
the “Cleared” column indicates that the problem still exists. Essentially, this screen 
shows the same diagnostic messages as available on the controller via the lower display 
window. 
See Section 
7 for other information about Troubleshooting and Diagnostics.
