7.2 Programming
This section is for users who write their own programs. A datalogger program
to measure this sensor can be created using Campbell Scientifics’ Short Cut
Program Builder software. You do not need to read this section to use Short
Cut.
Wind speed is typically measured an a datalogger pulse channel. The P2546A
uses the CRBasic PulseCount() instruction configuring the pulse channel for
switch closure with frequency counting. For dataloggers programmed with
EDLOG, specify configuration code 22 to output frequency in Hertz.
The expression for wind speed (U) is:
U = MX + B
where
M = multiplier
X = number of pulses per second (Hertz)
B = offset
