to the datalogger.

9. If the sensor is connected to the datalogger, as shown in the wiring

diagram in step 6, check the output of the sensor in the datalogger
support software data display to make sure it is making reasonable
measurements.

The 014A is constructed of corrosion-resistant, stainless-steel and anodized
aluminum. Its three-cup anemometer assembly contains a sealed magnetic reed
switch. Rotation of the cup wheel produces a pulse that is directly proportional
to wind speed.

The accompanying Met One manual contains additional information on
operating principals, installation, and maintenance.

The –L portion of the model number indicates that the 014A has a user­specified cable length. TABLE 5-1 gives the recommended lead length for

Met One 014A Wind Speed Sensor

If you are programming your datalogger with Short Cut, skip Section 7.3,
Wiring, and Section 7.4, Programming. Short Cut does this work for you. See

Section 4, Quickstart, for a Short Cut tutorial.

Locate wind sensors away from obstructions (for example, trees and buildings).
As a general rule, there should be a horizontal distance of at least ten times the
height of the obstruction between the sensor and the obstruction. If it is
necessary to mount the sensors on the roof of a building, the height of the
sensors, above the roof, should be at least 1.5 times the height of the building.
See Section 10, References, for a list of references that discuss siting wind
speed and direction sensors.

The 014A can be attached to a CM200-series crossarm via a 1049 NU-RAIL
fitting or a CM220 Right Angle Mounting Bracket. The procedure for using
these mounts is provided in the quickstart (Section 4.1.3, Mount to a Tripod or
Tower).

Alternatively, the 014A can be attached to the top of a CM106B, CM110,
CM115, or CM120 tripod via the CM216 Sensor Mounting Kit. The CM216
extends 10 cm (4 in) above the mast of the tripod.

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, Use SCWin to Program
Datalogger and Generate Wiring Diagram. If you wish to import Short Cut
code into either CRBasic Editor or Edlog 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 and Edlog
dataloggers are provided in the following sections. Complete program
examples for select dataloggers can be found in Appendix B, Example
Programs.

Wind speed is typically measured with a pulse count instruction, using the
switch closure configuration. For dataloggers programmed with Edlog, specify
configuration code 22 to output frequency in hertz.

If using a control port, see Appendix B.2, Control Port Example Program.

The expression for wind speed (U) is:

U = MX + B

where

M = multiplier
X = number of pulses per second (hertz)
B = offset

TABLE 7-3 lists the multipliers (M) and offsets (Off) to obtain meters/second
or miles/hour when the pulse count instruction is configured to output the result
in Hz.

8. Maintenance

8.1 Suggested Maintenance Schedules

8.1.1 6 to 12 Month Periodic Service

by the execution interval in seconds

Visually inspect the anemometer cups for cracks and breaks, and make sure
that each arm is securely attached to the cup assembly hub. Also check to see
that the vent hole, located at the base of the sensor, is unobstructed.

Special caution is advised under adverse conditions of high winds, heat, and/or
sandy areas. Look for abrupt stopping of the cup assembly with slow cup
rotation. If this occurs, the bearings may need to be replaced.

11

9. Troubleshooting

Symptom: No wind speed

10. References

1. Check that the sensor is wired to the pulse channel specified by the pulse
count instruction.

2. Disconnect the sensor from the datalogger and use an ohm meter to check
the reed switch. The resistance between the white and black wires should
vary from infinite (switch open) to less than 1 ohm (switch closed) as the
cup wheel is slowly turned.

3. Verify that the Configuration Code (switch closure, hertz), and multiplier
and offset parameters for the pulse count instruction are correct for the
datalogger type.

Symptom: Wind speed does not change

1. For the dataloggers that are programmed with Edlog, the input location
for wind speed is not updated if the datalogger is getting “Program Table
Overruns”. Increase the execution interval (scan rate) to prevent overruns.

NOTE

Appendix A. Importing Short Cut Code

This tutorial shows:

• How to import a Short Cut program into a program editor for

additional refinement.

• How to import a wiring diagram from Short Cut into the comments of

a custom program.

A.1 Importing Short Cut Code into a Program Editor

Short Cut creates files that can be imported into either CRBasic Editor or
Edlog program editor. These files normally reside in the

C:\campbellsci\SCWin folder and have the following extensions:

• .DEF (wiring and memory usage information)

• .CR2 (CR200(X) datalogger code)

• .CR1 (CR1000 datalogger code)

• .CR8 (CR800 datalogger code)

• .CR3 (CR3000 datalogger code)

• .CR9 (CR9000(X) datalogger code)

• .CR5 (CR5000 datalogger code)

• .DLD (contain code for CR10(X), CR23X, CR500, CR510, 21X, or

CR7(X) dataloggers)

The following procedures show how to import these files for editing.

A.1.1 CRBasic Dataloggers

Use the following procedure to import Short Cut code into CRBasic Editor
(CR200(X), CR1000, CR800, CR3000, CR5000 CR9000(X) dataloggers).

1. Create the Short Cut program following the procedure in Section 4,
Quickstart. Finish the program and exit Short Cut. Make note of the file
name used when saving the Short Cut program.

2. Open CRBasic Editor.

3. Click File | Open. Assuming the default paths were used when Short Cut
was installed, navigate to C:\CampbellSci\SCWin folder. The file of
interest has a “.CR2”, “.CR1”, “.CR8”, “.CR3”, “.CR9”, or “.CR5”
extension, for CR200(X), CR1000, CR800, CR3000, CR9000(X), or
CR5000 dataloggers, respectively. Select the file and click Open.

4. Immediately save the file in a folder different from \Campbellsci\SCWin,
or save the file with a different file name.

Once the file is edited with CRBasic Editor, Short Cut can no
longer be used to edit the datalogger program. Change the name
of the program file or move it, or Short Cut may overwrite it next
time it is used.

A-1

Appendix A. Importing Short Cut Code

NOTE

5. The program can now be edited, saved, and sent to the datalogger.

6. Import wiring information to the program by opening the associated .DEF
file. Copy and paste the section beginning with heading “-Wiring for
CRXXX–” into the CRBasic program, usually at the head of the file.
After pasting, edit the information such that a ' character (single quotation
mark) begins each line. This character instructs the datalogger compiler to
ignore the line when compiling the datalogger code.

A.1.2 Edlog Dataloggers

Use the following procedure to import Short Cut code into the Edlog program
editor (CR10(X), CR500, CR510, CR23X, 21X, and CR7(X) dataloggers).

1. Create the Short Cut program following the procedure in Section 4,
Quickstart. Finish the program and exit Short Cut. Make note of the file
name used when saving the Short Cut program.

2. Open Edlog.

3. Click File | Document DLD File. Assuming the default paths were used
when Short Cut was installed, navigate to C:\CampbellSci\SCWin folder.
The file of interest has a “.DLD” extension. Select the file and click
Open. The .DLD file, which is a type of ASCII machine code, is
imported, documented, and, when saved, given a “.CSI” extension.

4. Immediately save the file in a folder different from \Campbellsci\SCWin,
or save the file with a different file name.

Once the file is edited with Edlog, Short Cut can no longer be used
to edit the program. Change the name of the program file or move
it, or Short Cut may overwrite it.

5. The program can now be edited, saved, and sent to the datalogger.

6. Import wiring information to the program by opening the associated .DEF
file. Copy and paste the section beginning with heading “-Wiring for
CRXXX–” into the Edlog program, usually at the head of the file. After
pasting, edit the information such that a ; (semicolon) begins each line,
which instructs the datalogger compiler to ignore the line when compiling
the datalogger code.

Appendix C. Sensor Maintenance

C.1 Reed Switch Replacement Procedure

To verify parts and locations, refer to the cable and parts diagrams (FIGURE
C-2 and FIGURE C-3) and the parts list (TABLE C-1).

A. Remove sensor from mounting arm and disconnect cable.

B. Remove the cup assembly.

C. Remove the three Philips screws at the top of the sensor and lift out the

bearing mount assembly.

D. Unsolder the leads of the reed switch and remove the switch from the two

mounting terminals, see the parts diagram.

E. Solder the new switch onto the sides of the switch mount terminals (form

a loop in the relay leads to obtain proper lead length -- DO NOT CUT
THE RELAY LEADS.) Measure the distance between the bottom of the
rotating magnet and the top of the switch envelope, as shown in FIGURE
C-1. The spacing should measure between 0.01 and 0.02 inches.

F. Spin the shaft to verify switch operation by listening for a faint sound of

the switch closure. If the switch cannot be heard, move the switch slightly
closer to the magnet assembly.

G. Reassemble sensor.

FIGURE C-1. Reed switch assembly

C.2 Bearing Replacement Procedure

The bearings used in the 014A sensor are special stainless steel ball bearings
with a protective shield. Bearings are lubricated and sealed. DO NOT

LUBRICATE BEARINGS AS THE LUBRICATION WILL ATTRACT
DUST AND INHIBIT BEARING OPERATION.

A. Follow steps A, B, and C in reed switch replacement procedures.

B. Loosen set screws in magnet assembly, lift shaft and collar up and out of

bearing mount. Be sure to retain lower spacer.

Appendix D. Theory of Operation

D.1 Mechanical

The sensor’s cup assembly consists of three aluminum cups mounted on a cup
assembly hub. A stainless steel shaft, which rotates on precision-sealed ball
bearings, connects the cup assembly to a magnet assembly. When the shaft is
rotated, the turning magnet assembly causes a reed switch to close. There are
two contacts (reed switch closures) per revolution. The frequency of closures
is linear from threshold to 45 m s

D.2 Calibration

The 014A sensor has a threshold speed of 0.447 m s–1and follows the equation:

–1

.

V = 0.447 + f/1.250 where
V = wind speed (m s
f = output frequency (hz,)

or, V = 1.0 + f/0.5589
where V = wind speed (mph), and
f = output frequency (hz.)
