CPEC200 Closed-Path Eddy-Covariance
System
1. Introduction
The CPEC200 is a closed-path, eddy-covariance (EC) flux system used for
long-term monitoring of atmosphere–biosphere exchanges of carbon dioxide,
water vapor, heat, and momentum. This complete, turn-key system includes a
closed-path gas analyzer (EC155), a sonic anemometer head (CSAT3A),
datalogger (CR3000), sample pump, and optional valve module for automated
zero and span.
Before using the CPEC200, please study:
•
Section 2, Cautionary Statements
•
Section 3, Initial Inspection
•
Section 5, Installation
Operational instructions critical to the preservation of the system are found
throughout this manual. Before using the CPEC200, please study the entire

2. Cautionary Statements
•
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.
