4.2 Koneksyon Sonde
Ensure the wind fan probe is securely connected to the main unit via its cable. The connector should fit snugly into the port on the top of the main unit.
5. Operasyon Enstriksyon
5.1 Power On/Off
- Pou limen aparèy la, peze epi kenbe bouton an ON/OFF bouton.
- Pou etenn aparèy la, peze epi kenbe bouton an ON/OFF button again. The device also features an auto-power-off function to conserve battery life.
5.2 Chanje Inite Mezi yo
With the device powered on, short press the INITE button (which is also the ON/OFF button) to cycle through available wind speed units (m/s, Ft/min, Knots, Km/h, Mph) and temperature units (°C, °F).
5.3 Wind Speed and Temperature Measurement
The device automatically displays wind speed and temperature upon power-on. Extend the telescopic rod of the wind fan probe and position the fan in the airflow you wish to measure. Ensure the fan is facing directly into the wind for accurate readings.
