4. Press to view average readings of other parameters.
5. Press AVG again to return to normal mode.
Air Volume
You have 3 options for measuring air volume:
1. Enter the square dimensions of the vent or duct you wish to
measure directly into the meter. (see Setup p. 11).
2. The App offers you additional options for calculating air
volume. (see p. 15)
3. Use the optional airflow cones. Make sure the meter is fully
inserted and locked into the cone. indicates that it
recognizes the cone. The meter will now automatically
calculate air volume, without reference to any measurements
you may have previously entered.
Note:
The vent size must be no larger than the cone.
CO2
The CO2 sensor is built into the rear of the center of the vane.
Press repeatedly to reach CO2 in the upper display.(See
p. 11 for CO2 calibration). For accurate readings at high
altitudes CO2 should be compensated for air pressure. This
can be done directly on the meter (see Setup P4.0 on p. 11,
or via the App. see p. 15)
