Met One 034B Wind Set
The dataloggers can also measure wind speed on a control port. With this
option the black wire is connected to the 5 V terminal.
A 034B-L Wind Set purchased directly from Met One Instruments
has a different configuration on the 6-pin connector. In addition,
they do not have the 10 kΩ resistance on the excitation line. The
wiring diagram and the multiplier and offset, for wind direction,
are different than the examples in this document.
7.4 Programming
Short Cut is the best source for up-to-date datalogger programming code.
Programming code is needed,
• when creating a program for a new datalogger installation
• when adding sensors to an existing datalogger program
If your data acquisition requirements are simple and you are connecting the
sensor to a pulse port, you can probably create and maintain a datalogger
program exclusively with Short Cut. If your data acquisition needs are more
complex, the files that Short Cut creates are a great source for programming
code to start a new program or add to an existing custom program.
Short Cut cannot edit programs after they are imported and edited
in CRBasic Editor.
A Short Cut tutorial is available in Section 4.2, Step 2—Use Short Cut to
Program Datalogger and Generate Wiring Diagram. If you wish to import
Short Cut code into CRBasic Editor to create or add to a customized program,
follow the procedure in Appendix A.1, Importing Short Cut Code into a
Program Editor. Programming basics for CRBasic dataloggers are provided in
the following sections. Complete program examples for select CRBasic
dataloggers can be found in Appendix B, Example Program. Programming
basics and programming examples for Edlog dataloggers are provided at
www.campbellsci.com/old-manuals .
7.4.1 Wind Speed
Wind speed is measured with the Pulse Count instruction, using the Switch
Closure configuration and set to output frequency in Hertz (see Appendix B,
Example Program, for examples).
