Fresh Air Correction & Calibration

Fresh Air Correction

It is strongly suggested that the unit be corrected in a sunny, outdoor environment that is well ventilated. Do not correct

the unit in places crowded with people or close to areas with high CO

fireplaces.

To correct the unit for CO

unit will flash continually for about 5 minutes, then return to normal operation.

To abort correction at any time, simply turn the meter off.

CAUTION: The meter is corrected at ambient air of around 400ppm. Do not correct the meter in an environment with an

unknown CO

concentration. Doing this could lead to inaccurate measurements.
