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

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.
