Operating Instructions
Power ON/OFF
Turn the meter on by pressing the button. To turn the meter off, press and hold the button for 3 seconds.
Taking Measurements
The meter starts taking measurements when powered on and updates readings every 2 seconds.
Note: Make sure the CO the "CAL" position.
Rapid environment changes (i.e., moving your meter from indoors to outdoors) may cause inaccurate readings, therefore,it is always recommended to allow your meter to get acclimated to its new environment (approx. 10 to 15 minutes). Do not hold the meter close to your mouth or any other source of CO2.
Unit of Measurement Selection (°C/°F)
When the meter is powered on press the button to toggle between Celsius and Fahrenheit.
Note: The default unit of measurement is Celsius (°C). The meter will automatically save the last selected unit of measure when turned off.
Data Hold

Min/Max and Average Readings
When in this mode, the unit simultaneously monitors and stores the minimum, maximum and average values into the internal memory while continuously updating/refreshing the measurement values.
1. Press the button once, the MIN indicator will appear on the LCD display. The minimum values (CO2, humidity and temperature) are displayed and will automatically update when new minimum data values are measured.
2. Press the button again and the MAX indicator will appear on the LCD display. The maximum values (CO2, humidity and temperature) are displayed and will automatically update when new maximum data values are measured.
3. Press the button a third time and the short-term exposure limit (STEL) indicator will now appear on the LCD display. The STEL average limit for the past 15 minutes will be displayed and will automatically be updated every minute.
4. Press the button a fourth time and the time weight average (TWA) indicator will now appear on the LCD display. The TWA limit for the past 8 hours will be displayed and will automatically be updated every 10 minutes.
If the meter has been powered on for less than
15 minutes, the STEL and TWA values will only reflect the
weighted average of readings taken since it was powered on.
If the meter does not have enough data to display STEL
and TWA, "----" will appear on LCD display.
5. Press the TWA" indicators will blink simultaneously while continuing to update the readings in memory and can be viewed by returning to the appropriate function. While in this function, the meter is displaying the current measurement values only.

Appendix A – Recommended Guidelines
NIOSH Recommendations
• 250 to 350ppm: normal outdoor ambient concentrations.
• 600ppm: minimal air quality complaints.
• 600 to 1000ppm: less clearly interpreted.
• 1000ppm: indicates inadequate ventilation; complaints such as
headaches, fatigue, and eye/throat irritation will be more widespread. 1000ppm should be used as an upper limit for indoor levels.
ASHRAE Standard 62 to 1989: 1000ppm
• CO2 concentration in occupied building should not exceed 1000ppm.
Building Bulletin 101 (BB101): 1500ppm
• UK standards for schools say that CO2 at averaged over the whole day
(i.e. 9am to 3.30pm) should not exceed 1500ppm.
OSHA: 5000ppm
• Time weighted average over ve 8-hour work days should not
exceed 5000ppm.
Germany, Japan, Australia: 5000ppm
• 8 hours weighted average in occupational exposure limit is 5000ppm.
Product Care
To keep your instrument in good working order we recommend the following:
