You can order WXT532 with either 4 … 20 mA scaling or 0 … 20 mA scaling.

You can scale the output with the command aSU.

Example commands to set 4 … 20 mA operation:

Parameter Description
Wind speed gain aSU,a=0.333333<cr><lf>
Wind speed offset aSU,b=4 <cr><lf>
Wind speed minimum aSU,c=0<cr><lf>
Wind speed maximum aSU,d=22<cr><lf>
WS error indication aSU,e=2<cr><lf>
Wind direction gain aSU,f=0.044444<cr><lf>
Wind direction offset aSU,g=4<cr><lf>
WD minimum aSU,h=0<cr><lf>
WD maximum aSU,j=22<cr><lf>
WD error indication aSU,k=2<cr><lf>

The output o in mA is o=i* gain + offset. o is clamped between min and max. If wind measurement fails, the output value is err.
