2. Product Overview and Features
The Aicevoos H7 Digital Anemometer is equipped with several features to provide comprehensive environmental measurements.
Key Features:
- Wind Velocity Measurement: Measures wind speed in 6 selectable units: Feet per minute (ft/m), Feet per second (ft/s), Miles per hour (mph), Knots (knots), Kilometers per hour (km/h), and Meters per second (m/s).
- Wind Humidity & Temperature: Measures ambient temperature in Celsius (0℃-45℃) or Fahrenheit (32℉-113℉) and relative humidity (0.0% ~99.9%RH).
- CFM Display: Directly displays Cubic Feet per Minute (CFM) for air volume assessment in HVAC, vents, and dust collectors.
- Large Backlit LCD Screen: Provides clear readings in various lighting conditions.
- Lightweight and Portable: Designed for easy handling and convenient storage.
- Automatic Shut-off: Conserves battery power by turning off after 10 minutes of inactivity.
- Overload Prompt: Indicates when wind speed or temperature exceeds safe operating limits.

3. Setup
3.1. Unpacking and Inspection
Carefully remove the anemometer from its packaging. Inspect the device for any signs of damage.
3.2. Package Contents
The package should contain the following items:
- 1x Aicevoos H7 Digital Anemometer
- 3x AAA Batteries (Note: Product specifications indicate batteries are not included, but feature bullets mention they are. Please verify upon receipt.)
- 1x User Manual
- 1x Carry Pouch
3.3. Battery Installation
- Locate the battery compartment cover on the back of the device.
- Use a small screwdriver to open the battery compartment.
- Insert three AAA batteries, ensuring correct polarity (+/-).
- Replace the battery compartment cover and secure it with the screw.
4. Operating Instructions
4.1. Power On/Off
- To power on the device, press the red power button.
- To power off, press and hold the red power button for a few seconds, or allow the device to automatically shut off after 10 minutes of inactivity.
4.2. Backlight Control
- Press the light bulb icon button to turn the LCD backlight on or off.
4.3. Unit Selection
- Press the UNIT button to cycle through different wind velocity units (m/s, km/h, ft/s, ft/m, Knots, mph).
- To change temperature units (℃/℉), press the SET button.
4.4. Function Selection (FUNC Button)
The FUNC button allows you to switch between various display modes and functions. Refer to the on-screen indicators for the active mode.
4.5. Data Record (REC Button)
Use the REC button to record data. Specific recording functions (MAX, MIN, AVG) are typically accessed via this button in conjunction with other controls.
5. Measurement Modes
5.1. Wind Speed Measurement
Hold the anemometer so that the fan is exposed to the wind flow. The current wind speed will be displayed on the LCD screen in the selected unit.
Figure 3: Wind speed measurement. The image shows the anemometer held to measure wind speed, with the display showing a reading.
5.2. Wind Power Level Measurement
The device can display the wind power level, typically ranging from 0-12, with an accuracy grade of ±1. This provides a qualitative assessment of wind intensity.
Figure 4: Wind power level measurement. The display shows the wind power level alongside other readings.
5.3. Temperature and Humidity Measurement
The H7 measures ambient temperature and relative humidity. Ensure the sensor is exposed to the environment you wish to measure.

5.4. Air Volume Measurement (CFM/CMM/CMS)
For air volume measurement, align the fan of the instrument vertically with the air outlet. The cross-sectional area of the air outlet must be input into the device (if applicable, refer to advanced settings in the full manual) before accurate air volume measurements in Cubic Feet per Minute (CFM), Cubic Meters per Minute (CMM), or Cubic Feet per Second (CMS) can be obtained.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Check battery polarity. Replace with fresh AAA batteries. |
| Inaccurate readings. | Obstructed impeller, sensor dirty, or incorrect unit selected. | Ensure impeller is clear. Clean sensors. Verify selected measurement units. |
| "OL" (Overload) displayed. | Wind speed or temperature exceeds the device's measurement range. | Move to an environment within the specified operating limits (wind speed < 45m/s, temperature between -10℃ and 50℃). |
| Backlight not working. | Backlight turned off or low battery. | Press the backlight button. Replace batteries if low. |
