Introduction
The CS300, manufactured by Apogee Instruments, measures total sun and sky
solar radiation for solar, agricultural, meteorological, and hydrological
applications. Its spectral range of 360 to 1120 nanometers encompasses most
of the shortwave radiation that reaches the Earth’s surface. This pyranometer
connects directly to our dataloggers. Its output can be measured by all of our
dataloggers.

Cut Help, which is accessed by clicking on Help | Contents |
Programming Steps.
8.
If LoggerNet, PC400, RTDAQ, or PC200W is running on your PC, and the
PC to datalogger connection is active, you can click Finish in Short Cut
and you will be prompted to send the program just created 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.
Overview
The CS300 measures incoming solar radiation with a silicon photovoltaic
detector mounted in a cosine-corrected head. Output from the detector is a
current, which is converted to voltage by a potentiometer potted in the sensor
head. The resistance of the potentiometer is adjusted when the sensor is
calibrated so that all sensors have the same output sensitivity.
The CS300 is calibrated against a Kipp and Zonen CM21 under natural
sunlight to accurately measure sun plus sky radiation (360 to 1120 nm). The
CS300 should not be used under vegetation or artificial lights.
During the night, the CS300 may read slightly negative incoming solar
radiation. This negative signal is caused by RF noise passing through the
photo-diode. Negative values may be set to zero in the datalogger program.
For more theoretical information on the silicon photovoltaic detector see Kerr,
J. P., G. W. Thurtell, and C. B. Tanner: 1967, “An integrating pyranometer for
climatological observer stations and mesoscale networks”, J. Appl. Meteor., 6,
688-694.

The black outer jacket of the cable is Santoprene® rubber. This
compound was chosen for its resistance to temperature extremes,
moisture, and UV degradation. However, this jacket will support
combustion in air. It is rated as slow burning when tested
according to U.L. 94 H.B. and will pass FMVSS302. Local fire
codes may preclude its use inside buildings.
Installation
If you are programming your datalogger with Short Cut, skip Section 7.3,
Wiring to the Datalogger, and Section 7.4, Programming. Short Cut does this
work for you. See Section 4, Quickstart, for a Short Cut tutorial.
7.1
Siting
The CS300 should be mounted such that no shadows or reflections are cast on
it by the tripod/tower or other sensors. The sensor should be mounted with the
cable pointing towards the nearest magnetic pole. For example, in the
Northern Hemisphere, point the cable toward the North Pole.
Mounting height is not critical for the accuracy of the measurement. However,
pyranometers mounted at heights of 3 m or less are easier to level and clean.

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, 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.
NOTE
Short Cut cannot edit programs after they are imported and edited
in CRBasic Editor.
A Short Cut tutorial is available in Section 4, Quickstart. If you wish to import
Short Cut code into either Edlog or CRBasic Editor to create or add to a
customized program, follow the procedure in Appendix A, Importing Short Cut
Code Into CRBasic or Edlog Editor. Programming basics for CRBasic and
Edlog dataloggers are provided below. Complete program examples for select
dataloggers can be found in Appendix B, Example Programs.
The output from the CS300 is 0.2 mV per Wm–2. The voltage signal from the
CS300 is measured using the single-ended voltage instruction (VoltSE in
CRBasic or Volt (SE) (P1) in Edlog). Dataloggers that use CRBasic include
the CR200(X), CR800, CR850, CR1000, CR3000, CR5000, and CR9000(X).
Dataloggers that use Edlog include CR7, CR10(X), CR510, and CR23X.
Solar radiation can be recorded as an average flux density (W m–2) or daily
total flux (MJ m–2). The appropriate multipliers are listed in TABLE 7-2.
Negative values should be set to zero before being processed.

Nearby AC power lines, electric pumps, or motors can be a source of electrical
noise. If the sensor or datalogger is located in an electrically noisy
environment, the measurement should be made with the 60 or 50 Hz rejection
integration option as shown in the example programs.
7.4.1 Total Solar Radiation
If solar radiation is totalized in units of kJ m–2, there is a possibility of
overranging the output limits. For CRBasic dataloggers, you can avoid this by
using the IEEE4 or long data format. With the Edlog dataloggers the largest
number that the datalogger can output to final storage is 6999 in low resolution
(default), and 99999 in high resolution.
For Edlog dataloggers, if you assume that the daily total flux is desired in kJ m–
and assume an irradiance of 0.5 kW m–2, the maximum low resolution output
limit will be exceeded in just under four hours. This value was found by taking
the maximum flux the datalogger can record in low resolution and dividing by
the total hourly flux.
2
3.9 hr =
6999 kJ m −2
( 0.5 kJ m −2 s −1)( 3600 s hr −1)
(1)
To circumvent this limitation for Edlog dataloggers, record an average flux.
Then, during post processing, multiply the average flux by the number of
seconds in the output interval to arrive at an output interval flux. Sum the
output interval totals over a day to find a daily total flux.
Another alternative for Edlog dataloggers is to record total flux using the high
resolution format. Instruction 78 is used to switch to the high resolution. The
disadvantage of the high resolution format is that it takes more memory per
data point.

CS300 Pyranometer
8.
Maintenance and Calibration
On a monthly basis the level of the pyranometer should be checked. Any dust
or debris on the sensor head should be removed. The debris can be removed
with a blast of compressed air or with a soft bristle, camel hair brush.
CAUTION
Handle the sensor carefully when cleaning. Be careful not
to scratch the surface of the sensor.
Recalibrate the CS300 every three years. Obtain an RMA number before
returning the CS300 to Campbell Scientific, Inc. for recalibration.
9.
Troubleshooting
Symptom: –9999 or radiation values around 0
1.
Check that the sensor is wired to the single-ended channel specified by the
measurement instruction.
2.
Verify that the range code is correct for the datalogger type.
3.
Disconnect the sensor leads from the datalogger and use a DVM to check
the voltage between the red (+) and the black (–) wires. The voltage
should be 0 to 200 mV for 0 to 1000 Wm–2 radiation. No voltage
indicates a problem with either the photodiode or the shunt resistor, both
of which are potted in the sensor head and cannot be serviced.
Symptom: Incorrect solar radiation
NOTE
12
1.
Make sure the top surface of the sensor head is clean, and that the sensor
is properly leveled.
2.
Verify that the range code, multiplier and offset parameters are correct for
the desired engineering units and datalogger type.
Jumps of 3 to 6 Wm–2 are typical of CR200(X) measurements, due
to the 0.6 mV CR200(X) resolution and the 0.2 mV/Wm–2 CS300
sensitivity.

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)
.CR6 (CR6 datalogger code)
.CR2 (CR200(X) datalogger code)
.CR1 (CR1000 datalogger code)
.CR8 (CR800 or CR850 datalogger code)
.CR3 (CR3000 datalogger code)
.CR5 (CR5000 datalogger code)
.CR9 (CR9000(X) 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 Datalogger

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.
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
Use the following procedure to import Short Cut code into the Edlog program
editor (CR10(X), CR500, CR510, CR23X, CR7, or 21X dataloggers).
NOTE
A-2
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.

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 B. Example Programs
The following programs measure the CS300 every 10 s and convert the
millivolt output to Wm–2 and MJm–2. Both programs output an hourly average
flux (Wm–2), and a daily total flux density (MJm–2). Negative values are set to
zero before being processed. Wiring for the examples is given in TABLE B-1.
