Missing Readings
If WMT700 is not able to measure the wind, it indicates a missing
reading in the output. Most common reasons for measurement problems
are ice, birds, or other foreign objects on the line of measurement.
When the WMT700 profile is used, WMT700 indicates missing readings
by showing 999 in the data messages.
Example:
When WMT700 Data Message 22 is polled, missing readings are
indicated with the following response:
