After the command is issued to the sensor, it will respond with the
following prompt:
Enter actual temperature in xx.x C
It is most important to enter the temperature to the tenth of degree
Celsius with a decimal point. A leading minus sign is allowed but is not
likely needed since this should be an indoor operation. After entry of the
known ambient temperature, the sensor will respond with the following:
Wait for new constant to be saved.
After a short delay, the sensor will respond with the following:
Configuration change saved, re-initializing.
The sensor will then go through the standard power on initialization
routine and output.
WCDV Command
This command returns data that is calculated during the WCAL self
calibration command. The command format is:
WCDV CR LF
The sensor response to this command is two rows of data.The first row
of data are three ASCII TAB delimited numbers representing the zero
wind speed sonic transit time average for each of the three measurement
paths between transducer pairs. The values returned will change with
changes in ambient temperature at the time the WCAL command that
created them was issued. For N, S, and E representing north, south and
east transducers, the side order for the three data values is S-N, N-E,
then E-S.
The second row of data are six ASCII TAB delimited signed numbers
representing the zero offsets the sensor will apply to each of the six raw
sonic transit times measured between pairs of transducers. The data
order is S to N, N to S, N to E, E to N, E to S, then S to E.
This command may be used to determine if the sensor has been self
calibrated already. If the command returns three 20000 values in the
first row and six 0 values in the second row, these are the default values
and the sensor is uncalibrated. Be sure to run the WCAL command
before deploying if this is the case.
