4. Návod k obsluze
4.1 Zapnutí/vypnutí
Stiskněte tlačítko Moc tlačítko (
) 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.
- Stiskněte tlačítko JEDNOTKA 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.
- Stiskněte tlačítko ZAMĚSTNANEC button to enter airflow measurement mode.
- Použijte SOUBOR 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.
- Stiskněte tlačítko JEDNOTKA button to select the desired airflow unit.

5. Údržba
- Udržujte zařízení čisté a suché. Otírejte měkkým,amp tkanina. Nepoužívejte abrazivní čisticí prostředky nebo rozpouštědla.
- Ensure the fan blades are free from dust and debris to maintain measurement accuracy.
- Pokud se přístroj delší dobu nepoužívá, vyjměte baterii, abyste zabránili jejímu vytečení.
- Store the anemometer in its protective case in a cool, dry place.
6. Řešení problémů
- Žádný displej/zařízení se nezapíná:
- Zkontrolujte, zda je baterie správně vložena se správnou polaritou.
- Vyměňte baterii, pokud je slabá nebo vybitá.
- Nepřesná čtení:
- 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.
- Tlačítka nereagují:
- Turn the device off and then on again.
- Vyměňte baterii.
