Air Flow (volume) Calculation:
Keep the meter away from electromagnetic interference (EMI) which may cause erratic readings.
Please turn off the meter to avoid the sensor burned when you have finished testing the high wind speed (more than 20m/s) and remove the probe.
To extend the probe, hold the handle in one hand while pulling on the probe tip with the other hand. Do not hold the cable while extending the probe.
Remove the sensor protective cover, make sure the sensor window is fully exposed and the orientation is facing upstream.
