Whenever a warning message is reported on the analyzer display, if the RS-232 interface is in
the normal mode(i.e. not in quiet mode) the warning message is also sent to the RS-232
interface. These messages are helpful when trying to track down a problem with the analyzer and
for determining whether or not the DAS reports are actually valid. The warning message format
is for example:
W 194:11:03 0000 SAMPLE FLOW WARN
The format of a warning command is W command. Examples of warning commands are:
W LIST List all current warnings
W CLEAR ALL Clear all current Warnings
Individual warnings may be cleared via the front panel or the command line interface. To clear
the sample flow warning shown above the command would be:
W WSMPFLOW
