4. After selecting the sensor, click Wiring Diagram to see how the sensor is
to be wired to the datalogger. The wiring diagram can be printed now or
after more sensors are added.
5. Select any other sensors you have, then finish the remaining Short Cut
steps to complete the program. The remaining steps are outlined in Short
Cut Help

diagram in step 4, check the output of the sensor in the datalogger support
software data display to make sure it is making reasonable measurements.
5. Overview
The 034B, Wind Set is used to measure horizontal wind speed and direction.
Wind speed is measured with a three cup anemometer. Rotation of the cup
wheel opens and closes a reed switch at a rate proportional to wind speed.
Vane position is transmitted by a 10 k Ω potentiometer. With a precision
excitation voltage applied, the output voltage is proportional to wind direction.
The Met One manual contains additional information on the operating
principals, installation, and maintenance of the sensor. The Met One manual is
available at their website (

).
Cable length for the 034B is specified when the sensor is ordered. TABLE 5-1
gives the recommended cable length for mounting the sensor at the top of the
tripod/tower with a CM202 crossarm.
