4.1 Vklop/izklop
Pritisnite Moč gumb (
) to turn the device on or off. The device features an auto power-off function to conserve battery life.
4.2 Measuring Air Velocity
- Turn on the anemometer.
- Point the air velocity flow sensor (fan) directly into the airflow you wish to measure. Ensure the airflow passes through the fan blades.
- The current air velocity reading will be displayed on the LCD screen.
- Pritisnite ENOTA button to cycle through different measurement units (m/s, km/h, ft/s, knots, mil/h, fp/m).

4.3 Airflow Measurement (CFM/CMM/CMS)
- Turn on the anemometer.
- Pritisnite ZAPOSLENI button to enter airflow measurement mode.
- Uporabite NASTAVI button to input the cross-sectional area of the air duct or channel. This is crucial for accurate airflow calculation.
- Once the area is set, point the sensor into the airflow. The device will display the airflow volume in CFM, CMM, or CMS.
- Pritisnite ENOTA button to select the desired airflow unit.

4.4 Data Hold, Max/Min/Avg, and Record Functions
- Zadrževanje podatkov: Pritisnite PRIDRŽI gumb za zamrznitev trenutnega odčitka na zaslonu. Ponovno pritisnite za sprostitev.
- MAKS/MIN/POVPREČ: Pritisnite MAX / MIN / AVG button to cycle through maximum, minimum, and average readings during a measurement session.
- zapis: Pritisnite REC button to initiate data recording. (Note: Specific details on data storage and retrieval may be in the full manual or software).

5. Vzdrževanje
- Napravo hranite čisto in suho. Obrišite z mehko,amp krpo. Ne uporabljajte abrazivnih čistil ali topil.
- Ensure the fan blades are free from dust and debris to maintain measurement accuracy.
- Ko naprave dalj časa ne uporabljate, odstranite baterijo, da preprečite puščanje.
- Store the anemometer in its protective case in a cool, dry place.
6. Odpravljanje težav
- Ni zaslona/naprave, ki se ne vklopi:
- Check if the battery is installed correctly with the right polarity.
- Replace the battery if it is low or depleted.
- Netočni odčitki:
- Ensure the fan blades are clean and spinning freely.
- Verify that the sensor is pointed directly into the airflow.
- Check if the correct measurement unit is selected.
- For airflow measurements, confirm the air duct area setting is accurate.
- Gumbi se ne odzivajo:
- Izklopite napravo in jo nato ponovno vklopite.
- Zamenjajte baterijo.
