9.2 Wind speed
Symptom: No wind speed
1. Check that the sensor is wired to the pulse terminal specified by the pulse count instruction.
2. Disconnect the sensor from the data logger and use an ohmmeter to check the coil. The
resistance between the white and black wires for the 03101 and black and red wires for the
03002 should be a nominal 1300 Ω. Infinite resistance indicates an open coil; low resistance
indicates a shorted coil.
3. Verify that the configuration code, and multiplier and offset parameters for the pulse count
instruction are correct for the data logger type.
10. References
Component part numbers and other information is available in the R. M. Young 03002 manual
available at
www.campbellsci.com/03002-wind-sentry
. Because Campbell Scientific cables the
sensor, the wiring in the R. M. Young manual will be different than the wiring listed in this manual.
