2. Precautions
•
WARNING:
o
Do not connect or disconnect the EC155 gas analyzer head or the
CSAT3A sonic anemometer head from the EC100 electronics
while the EC100 is powered. Doing so can result in unpredictable
performance of the system or damage to the instrument head.
o
Grounding electrical components in the measurement system is
critical. Proper earth (chassis) grounding will ensure maximum
electrostatic discharge (ESD) protection and higher measurement
accuracy.
o
Use care when connecting and disconnecting tube fittings to
avoid introducing dust or other contaminants.
o
Do not overtighten the tube fittings. Consult Appendix
(p. J-1)
, for information on proper connection.
o
A power source for a CPEC300-series system should be designed
thoughtfully to ensure uninterrupted power. If needed, contact
Campbell Scientific for assistance.
o
Retain all spare caps and plugs as these are required when
shipping or storing any CPEC300-series system.
3. Initial Inspection
Upon receipt of a CPEC300-series system, inspect the packaging and contents
for damage. File damage claims with the shipping company.
Verify receipt of all components of the CPEC300-series system purchased.
Model numbers are found on each product. On cables, the model number is
usually found at the connection end of the cable. Check this information
against the enclosed shipping documents to verify the expected products and
the correct lengths of cable are included.
4. Overview
The CPEC300, CPEC306, and CPEC310 are three closely related closed-path,
eddy-covariance (EC) systems that are used for long-term monitoring of
atmosphere–biosphere exchanges of carbon dioxide, water vapor, heat, and
momentum. The CPEC300 is a basic, entry level system, the CPEC306 is a
mid-level, expandable system, and the CPEC310 is the high-end, expandable
system.
The CPEC306 and CPEC310 have options for a CDM-A116 that allows for
additional sensors for energy-balance and meteorological measurements. The
CPEC310 is equipped with a three-valve module to allow automatic zero-and-
span.
