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
