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
2
concentration such as
ventilating outlets or fireplaces.
To correct the unit for CO
2
, place the meter in the
calibration site and press and hold buttons 2 and 3
simultaneously. The 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
2
concentration.
Doing this could lead to inaccurate measurements.
