Usage with Wind Data Logger:

The RPM sensor can be connected to one of the anemometer channels as you would with a normal anemometer.

Your calibration values values for calculating RPM and total daily revolutions would be as follows (n = number of magnets used).

RPM:
Anemometer m (multiplier) = 60 / n
Anemometer b (offset) = 0

Total Daily Revolutions:
Counter m (multiplier) = 1 / n
Counter b (offset) = 0

So for an example, if you used Anemometer Channel 2 and two magnets, you could do the following:

Main Setup Menu > Anemometer Setup > Anemometer 2

AN_M2 = +0030.0000
AN_B2 = +0000.0000
Label2 = TURBINE RPM
AN2_UNIT = RPM


Main Setup Menu > Counter Setup > Counter 2

CNT_M2 = +0000.5000
CNT_B2 = +0000.0000
Label2 = TOTAL REVS
CNT2_UNIT = CNT
