- Page 2 Introduction Thank you for selecting the Model CO230 Carbon Dioxide Monitor. This meter measures CO concentration, air temperature, dew point, wet bulb temperature and relative humidity. The audio-visual alarm and alarm relay output make this is an ideal instrument for indoor air quality (IAQ) diagnostics. Carbon dioxide (CO is a gaseous component of the earth’s atmosphere.

Page 4: Operation
Power the unit by plugging the AC adaptor into the meter and into an AC source. The meter will switch ON with a short beep. The LCD will perform a 30 second countdown and then displays the current CO concentration, air temperature, and relative humidity. CO230-en-GB_v1.0 1/16... -

(lower left display) and Humidity (lower right display). In STEL and TWA modes, the main display shows the weighted average of CO readings for the prior 15 minutes (STEL) or 8 hours (TWA). The lower display shows the current AIR, DP/WB temperature and humidity. CO230-en-GB_v1.0 1/16... -
Page 6: Alarm Overview
The TWA mode will display a weighted average of the readings taken during the prior 8 hours of operation. 2. The CO230 requires at least 5 minutes to calculate STEL and TWA values. The display shows “----” during this time. - Page 7 Press SET to enter P3.1 for setting the temperature units. The currently selected unit (°C / °F) will be blinking in the lower display. To switch units press▲/DP WB or MXN/AVG/▼. Press SET to save the setting or press CAL/ESC to exit without saving and return to P3.0. CO230-en-GB_v1.0 1/16...
