The current alarm value will appear on the LCD. Press the “UP” and 
“DOWN” buttons to modify the ppm value by increments of 100. The 
alarm ranges from 100 to 9900ppm. When the desired alarm value is 
displayed, press the “ENTER” button to save, or press the “ESC” button 

to cancel.

When measured CO

2

 values are above the set limit the meter will start 

to beep. Press any button (except for the “POWER” button) to stop the 
beeping, or move the meter to a location where the ppm value is below 
the alarm limit. If the beeping does not stop, restart the meter.

Temperature Unit

To change the temperature scale from °C to °F, press and hold the “SET” 
button for 2 seconds. Press the “DOWN” button and “Unit” and P3.0 will 
appear on the LCD. Press the “ENTER” button, and modify the tempera

ture unit by pressing the “UP” or “DOWN” buttons. Press the “ENTER” 
button to save the setting, or press the “ESC” button to cancel. 

CO

2

 Calibration

This meter is calibrated at a standard 400ppm CO

2

 concentration. It’s sug-

gested to perform manual calibration regularly to maintain good accuracy. 
For a more thorough calibration and for maintenance for this product, 
please contact REED Instruments at [email protected].

Do not calibrate this meter in an environment with unknown CO

2

 con-

centrations. Manual calibration should be done in fresh outdoor air that 
is well ventilated and in sunny weather. Turn on the meter and hold down 
the “CAL” and “MODE” buttons simultaneously. “400ppm” and “CAL” will 
blink on the LCD indicating you have activated manual calibration, and will 
blink for approximately 5 minutes. When the blinking stops, CO

2

 calibra-

tion is complete, and the meter will automatically switch back to normal-
measuring mode. To abort the calibration, turn off the meter at any time. 

 

 

NOTE

: Ensure the batteries are with full voltage during the calibration to 

prevent from interruption or failed calibration.
