7.2 Warnings
Whenever a warning message is displayed on the display, it is also sent to the RS-232 output.
See Table 2-4 for a list of the warning messages. These messages are very helpful when trying to
track down a system problem and for determining whether or not DAS average data is actually
valid. The message format is:
"W DDD:HH:MM IIII WARNING MESSAGE<CRLF>"
An example of an actual warning message is:
"W 194:11:03 0000 SAMPLE FLOW WARN<CRLF>"
Warnings may be cleared via the RS-232 interface by issuing a command of the form:
"W COMMAND<CRLF>"
where "COMMAND" indicates which warning message to clear. For example, to clear the
"SAMPLE FLOW WARN" message, the host computer can issue the command:
"W WSMPFLOW<CRLF>"
To clear all warning messages:
"W CLEAR ALL<CRLF>"
Attempting to clear a warning which is not active has no effect. Table 7-2 lists the command to
use to clear each possible warning message.
