Error Indication
WMT700 provides advanced self-diagnostics for monitoring the status of
the wind sensor and the validity of the measurement data. You can use
the diagnostics as follows:
- To check the status of the wind sensor, include the status code item \er
in the data message. You need to convert the status code to a binary
number to verify the status. An error code does not indicate that the
wind data is invalid. For more information, see section Status Flags on
page 86.
- To check that the wind data is valid, include the \va item in the data
message. For more information, see section Items for Data Messages
on page 83.
- To check other diagnostics-related data, include the required items in
the data message. For more information, see section Items for Data
Messages on page 83.
