Voltage

When voltage is selected as the wind speed analog output, the

output from WMT700 varies linearly from 0 VDC at 0 miles per

hour to 1 VDC at 125 miles per hour. In SI units, the voltage

varies linearly from 0 VDC at 0 meters per second to 1 VDC at

55.88 meters per second.

Figure 49 below shows the voltage output when an adapter cable

for voltage output (227571SP) and a WS425 cable are used. With

WMT700, the wind speed signal appears at pin 15 (violet) of the

adaptor cable. The violet wire must be connected to V read

channel, and the pink wire must be connected to the analog

ground.
