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
•
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
(p. 2)
. If you wish to
import Short Cut code into CRBasic Editor to create or add to a customized
program, follow the procedure in Appendix
, Importing Short Cut Code Into
(p. A-1)
. Programming basics for CRBasic dataloggers are
provided in the following sections. A complete program example for a select
CRBasic datalogger can be found in Appendix
(p. B-1)
Programming basics and programming examples for Edlog dataloggers are

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
(p. B-1)
, for examples).
