Vaisala WINDCAP WMT700 Series, User Manual

Page: 139 / 210

The following WS425 F/G ASOS commands cannot be used with WMT700: WB ,
WFIRMWARE , WJ , WR , WCAL , WH , WCDV , WSTK , WL , WM , WN , WSST , and WATE . You can only
configure WMT700 in the configuration mode. For a list of configuration commands for
WMT700, see
5.3 Configuration (page 101) .
5.21.1.1 WA — Fetch Averaged Wind Speed and Direction
This command requests the averaged wind speed and direction message with peak winds.
WA <CR><LF>
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.
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.

5.21.1.2 WS — Fetch Internal Diagnostics Information
This command requests the verbose Built-In Test (BIT) results.
WS<CR><LF>
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
