Digital Anemometer
Before using the instrument, please read this manual carefully, and save it well for future using.
Introduction
This is a professional digital anemometer with stable performance, safety, and reliability. It is widely used in wind energy, meteorology, industry, agriculture, hydrology and water conservancy, environmental protection, highways, airports ports, etc.
Key Components:
- Fan blade
- Display
- Unit of temperature MAX/MIN
- Power key
- Data hold
- Backlight key
- Units of wind speed
Display Screen
The display shows readings for wind speed, temperature, and humidity. It also indicates units such as m/s, km/h, mil/h, ft/m, ft/s, knots, and °C/°F.
| Symbols | Description | Symbols | Description |
|---|---|---|---|
| MAX | Maximum value | m/s | Meter per second |
| MIN | Minimum value | Km/h | Kilometers per hour |
| AVG | Average value | mil/h | Miles per hour |
| °C | Celsius | ft/m | Foot per minute |
| °F | Fahrenheit | ft/s | Feet per sec |
| knots | Nautical miles per hour |
Considerations
- Do not touch the fan blade with force.
- Do not store or operate the instrument in areas with high temperature or humidity.
- In use, do not let the strong light directly shine on the fan, in order to avoid measurement errors.
- Avoid violent vibration.
- Remove the battery before storing the instrument for a long time.
Operation
Wind speed measurement:
- Press the UNIT button to turn on the power.
- Hold the anemometer and let the fan plane of the anemometer align vertically with the wind direction of the airflow for measurement.
- The display will show the wind speed, wind temperature, and wind humidity at the same time.
Data hold:
To freeze a displayed reading, press the MAX/MIN button. The "H" icon will appear and the most recent reading will appear on the display. Press the MAX/MIN button to exit the mode and return to normal mode.
Backlight on or off:
Press the UNIT button and hold it for more than 2 seconds to enable or disable the backlight function.
MAX/MIN/AVG function:
Press the MAX key to turn on the maximum function, and then press the MAX key to cycle through the maximum, minimum, and average values. Long pressing the MIN key for 2 seconds returns to normal measurement function.
Temperature unit selection:
Press the °C/°F key to select the temperature unit.
Wind speed unit selection:
Press the UNIT key to select the desired wind speed unit (m/s, km/h, mill/h, ft/m, ft/s, knots).
Auto shutdown function:
When the power is turned on, the automatic shutdown function is turned on by default. No operation within 10 minutes will automatically shut down.
If you need to cancel the auto-off function, press and hold the UNIT key before turning on the meter, then press the UNIT key to turn on the power, and then release the UNIT key after the meter is turned on, the auto-off function will be canceled.
Reboot to restore automatic shutdown function automatically.
When the meter turns on the auto-off function, the display will show the ✔ symbol; when the auto-off function is canceled, it will not show.
