• use white duct tape to secure probe to conduit

Anemometer notes

Testing each anemometer for

• propeller torque using anemometer torque disc (18310)
  • factory spec is 2.6 gm-cm (black nylon screw at 5cm and metal screw at 2cm)
    • 33821 moved with 0.2 gm-cm (a black nylon screw at 2cm radius), so this is much better than factory spec
    • 61996 moved with 0.5 gm-cm
  • tested both Clock Wise(CW) and Counter Clock Wise (CCW)
• Wind speed using anemometer drive (18802)
  • @200rpm = 0.98m/s. @1000rpm = 4.9m/s. @2000rpm = 9.8m/s
  • tested both CW and CCW
• Vane Torque using Vane Torque Gauge (18331)
  • mount the gauge, pull the string, if it moves with < 30 gm-cm of torque, golden.
  • tested both CW and CCW
• Wind Direction using Vane Angle Fixture Tower Mount (18212)
  • checked 3 directions
    • 33821 all within 1 degree of accuracy
    • 61996 reads 3 degrees less (ex: reads 177 when should be 180)
