5. Operating Instructions
5.1. Power On/Off
- To power on the device, press and hold the On/Off button for approximately 3 seconds until the display illuminates.
- To power off the device, press and hold the On/Off button for approximately 3 seconds.
- The device features an auto-off function after 5 minutes of inactivity to conserve battery. This can also be manually overridden.
5.2. Mode Selection
Press the MODE button to cycle through different measurement modes, such as wind speed, temperature, and airflow volume.
5.3. Unit Selection
Press the UNIT button to change the measurement units within the selected mode. For example, in wind speed mode, you can switch between m/s, km/h, ft/min, knots, and mph. For temperature, switch between ℃ and ℉.
5.4. Wind Speed Measurement
- Ensure the device is powered on and in wind speed measurement mode.
- Hold the anemometer so that the fan blades are directly facing the wind source.
- Read the wind speed value displayed on the LCD screen.

5.5. Airflow Volume Measurement (CFM/CMM/CMS)
- Switch to airflow volume measurement mode using the MODE button.
- Before measurement, you may need to set the area of the air duct or opening. Refer to the device's on-screen prompts or specific instructions for area input.
- Select the desired unit (CMM, CMS, or CFM) using the UNIT button.
- Position the anemometer's fan vertically with the air outlet or inlet to ensure accurate airflow measurement.
- Read the airflow volume value displayed on the LCD screen.

5.6. Data Hold Function
To temporarily freeze the current reading on the display, briefly press the SET button. Press it again to release the hold and resume live readings.
5.7. Backlight
To activate or deactivate the LCD backlight for improved visibility in low-light conditions, press the dedicated backlight button (often indicated by a sun or lightbulb icon, or combined with the SET button by holding it for >3 seconds). The backlight ensures clear reading of wind speed, wind volume, and temperature.

This image shows the anemometer's display with its backlight feature active, making the readings visible in darker settings.
5.8. MAX/MIN/CURRENT Readings
Press the MAX/MIN button to cycle through the maximum recorded value, the minimum recorded value, and the current real-time reading for the active measurement parameter.
6. Maintenance
6.1. Cleaning
- Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Ensure the fan blades are free from dust and debris for accurate readings. Use a soft brush or compressed air if necessary.
6.2. Storage
- Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- If storing for an extended period, ensure the battery is partially charged (around 50%) to prolong its lifespan.
6.3. Battery Care
- Recharge the battery when the low battery indicator appears on the display.
- Avoid completely draining the battery frequently, as this can reduce its overall lifespan.
7. Troubleshooting
