compliance with all national and local codes and OSHA requirements.
Installation should be attempted only by individuals familiar with
proper installation techniques and with codes, standards, and proper
safety procedures for control installations.
INTRODUCTION
The CX Series is a non-dispersive infrared analyzer designed for
measuring environmental CO
systems and indoor living spaces. Its measurement range
of 0-2000 or 0-5000 ppm covers the range required to
monitor compliance with ASHRAE or other ventilation
efficiency standards.
The CX Series provides a user-selectable 4-20mA or 0-10VDC
output. An LCD display is available to provide local indication
of CO concentration and facilitate the setup and calibra-
2
tion process. An adjustable setpoint relay is available for
direct control and alarm applications. Microprocessor-
based digital electronics and a unique self-calibration
algorithm improves long-term stability and accuracy.
