WA — Fetch Averaged Wind Speed and
Direction
This command requests the averaged wind speed and direction
message with peak winds.
WA
The response to the WA command consists of the averaged wind
speed and direction data, peak wind speed, and associated
direction. The average wind speed is a scalar running average of
the fundamental
1-second interval wind speed measurement made by WMT700.
For a description of the data message, see section WS425 F/G
ASOS Data Message on page 152.
You can set the wind averaging time and gust time with the
wndAvg and wndGustTime parameters. Set the wndVector
parameter to 0 to use scalar averaging.
The command also fetches the WMT700 status, the averaging
time for average and peak wind speed and wind direction, and
signal quality.
WS — Fetch Internal Diagnostics Information
This command requests the verbose Built-In Test (BIT) results.
WS
The command gives a textual run down of the results of all Built-
In Tests (BITs). In every line, except the bad reading counter, the
pass/fail indication is given with the single character P or F. This
is followed by the description of the measured parameter, which
is followed by the actual measured value.
The Bad 1 second readings counter is a running total of the
number of fundamental 1-second readings that the sensor flagged
as bad. This number rolls over to zero after reaching the count
value of 65535. It is initialized to zero on each power-up or any
other activity that performs a re-initialization of the sensor. The
time measurement quality indices are given for path numbers as
follows:
- Path 0 is from south transducer to north transducer
- Path 1 is from north transducer to south transducer
- Path 2 is from north transducer to east transducer
- Path 3 is from east transducer to north transducer
- Path 4 is from east transducer to south transducer
- Path 5 is from south transducer to east transducer
