The WT816A Anemometer offers various measurement modes and unit selections for comprehensive wind and temperature monitoring.

4.1 Button Functions

• Power Button (Red): Press once to turn on. Press and hold to turn off.
• UNIT Button: Cycles through different wind speed units (m/s, km/h, mph, knots, ft/min).
• MAX/MIN Button: Displays the maximum or minimum recorded wind speed during a measurement session.
• AVG Button: Displays the average wind speed during a measurement session.
• °C/°F Button: Switches the temperature display between Celsius and Fahrenheit.
• Backlight Button (Sun symbol): Toggles the LCD backlight on/off.

4.2 Taking Measurements

1. Power on the device using the red power button.
2. Hold the anemometer so that the fan (impeller) faces the direction of the wind or airflow you wish to measure.
3. The current wind speed and temperature will be displayed on the LCD.
4. Use the UNIT button to select your preferred wind speed unit.
5. Press the MAX/MIN button to view the highest or lowest wind speed recorded.
6. Press the AVG button to see the average wind speed.
7. Use the °C/°F button to switch between temperature units.
8. Activate the backlight in low-light conditions by pressing the Backlight Button.

4.3 Beaufort Scale

The device can also display wind force according to the Beaufort scale, providing a qualitative measure of wind conditions.

5. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the anemometer in a temperature environment between -30°C (-22°F) and 60°C (140°F). Prolonged storage outside this range may cause internal damage.
• Battery: If the device will not be used for a long period, it is recommended to remove the battery to prevent leakage and damage.
• Impeller: Ensure the impeller is free from dust and debris for accurate readings.

6. Troubleshooting

• Device not turning on: Check if the battery is correctly installed and has sufficient charge. Replace the battery if necessary.
• Inaccurate readings: Ensure the impeller is spinning freely and is not obstructed. Clean the impeller if dust or debris is present. Verify that the device is held correctly in the airflow.
• Display issues: If the display is dim or flickering, the battery may be low. Replace the battery.
