The SETMEA command configures the essential measurement parameters.

SETMEA [gaincorr] [offset] [powersave] [allowedspdchange] [maxinvalidspdcount] [thies] [calibmin] [calibmax] <value><cr>
gaincorr Anemometer transfer function gain parameter. Range: 0.0 … 10.0 (default: 0.101).
offset Anemometer transfer function offset parameter. Range: -10.0 … 10.0 (default: 0.348).
powersave Defines whether sensor power is pulsed or provided continuously. Pulsing saves power as the sensors are only powered when read.

0 = Continuous power

1 = Pulsed power (default); not used with WA25

allowedspdchange Maximum allowed difference in m/s between two adjacent samples in the sensor data. Range: 0.1 ... 25.0 (default: 10.0).
maxinvalidspdcount Maximum number of adjacent discarded samples in sensor data. Value 0 deactivates the check. Range: 0 ... 15 (default: 2).
thies Defines the sensor type:

0 = Vaisala WA15 or WA25 series (default)

1 = Thies first class anemometer and analog vane (default values for gaincorr and offset are automatically changed accordingly)

calibmin 4 mA calibration value for analog vane (default: 540)
calibmax 20 mA calibration value for analog vane (default: 2640)
value Value for the option
For a WA25 system, use the following settings:
  • powersave = 0
  • spdvoltlimit = 0
  • dirvoltlimit = 0

Example

>setmea offset 0.318 
       GAINCORR                 = 0.10100
       OFFSET                   = 0.31800
       POWERSAVE                = 1
       ALLOWEDSPDCHANGE         = 10.0
       MAXINVALIDSPDCOUNT       = 2
       THIES                    = 0
       CALIBMIN                 = 540
       CALIBMAX                 = 2640
