Vector SRC-C Quick Start Manual

SRC-C - Indoor CO2 Desktop Monitor
The SRC-C is an indoor CO2 monitoring desktop unit. Three LEDs in the colors
green, orange and red indicate the CO2 concentration of the room air. This
shows the user when to ventilate. A simple USB wall charger is used to power
the unit. The CO2 background calibration of the SRC-C guarantees for
accurate room air monitoring.

CO2 transmitter
The CO2 concentration is measured through non-dispersive infrared (NDIR) waveguide technology with ABC automatic
background calibration algorithm. The applied measuring technology guarantees excellent reliability and long-term stability.
The microprocessor samples the CO2 once per second. It calculates an averaging signal over a preset number of samples and
generates the output signal.
Automatic baseline calibration (ABC)
The ABC background calibration constantly supervises the measured CO2 concentrations. The calibration function expects the
CO2 values sink to 400 ppm when the room is not occupied. Over a period of several days the controller tries to reach this
value step by step through recalibration of 30ppm per day max. In order to reach the given accuracy, it is required that the
sensor is for at least 3 weeks in continued operation with no power reset.
NOTE: The ABC calibration works only in those applications where the CO2 concentration sinks regularly to fresh air
levels of 400 ppm. For special applications such as green houses, animal farms, etc. the ABC calibration should be
de-activated and the sensor should be manually calibrated. The automatic calibration can deactivate through the
external operation terminal. The Sensor can be calibrated by the client and does not need to be sent in for
calibration. For manual calibration see section "Error! Reference source not found." on page Error! Bookmark
not defined..
Minimum and maximum values (CO2)
Using a display & programming module OPU-S, the user has the option to read out and reset the CO2 minimum and maximum
values. The minimum and maximum values are automatically saved to the device and are available after a power interruption.
For OPU-S usage see section "Displaying Minimum and maximum values" on page 4.
