The most common instrument failures will be reported as a warning on the analyzer’s 
front panel and through the COMM ports. Section 12.1.1 explains how to use these 
messages to troubleshoot problems. Section 12.1.3 shows how to view and clear 
warning messages. Table 4-3 lists all warning messages for the current version of 
software.
