4.2.1 Operation

1. Extend the telescopic rod to the necessary length paying attention to the cable so that it can slide
freely and without strain;
2. Uncover the sensor;
3. Introduce the probe in the air flow being measured, maintaining the arrow at the top of the probe
parallel to the flow, as indicated in the figures.

NOTE:

the probe should be maintained orthogonal to the flow and not tilted in relation to it:

OK

NO

4. Proceed with measurement following the instructions provided in this chapter.
