1. Overview
This product is a high-performance digital anemometer using the infrared
laser beam and blade cutting method. It can measure wind speed, ambient
temperature, and humidity. Additionally, it allows the display of wind
spe ed an d airflow measur ements in diffe rent units. It finds wide
applications in environmental monitoring, wind energy assessment,
meteorological analysis, industrial, agricultural, environmental protection,
highway, airport, port, and various measurement scenarios.

3. Key Instructions
Power Button: Press and hold for more than 2 seconds to automatically turn the
device on or off. In the powered-on state, a short press of this button toggles the backlight on
and off.
Wind Speed/Volume Unit Switch Key: In measurement mode, press this key to
switch units. In setting mode, press this key to change the set values.
Data Hold Key: Short press to hold or release the current data; long press for more
than 2 seconds to enter the maximum and minimum value measurement mode.
Wind Speed/Volume Toggle Key: Short press to switch between wind speed and
airflow measurement; long press for more tha 2 seconds to enter the duct cross-sectional
area setting mode.

4. Operating Instructions
Wind Speed Measurement:
1. Power on the anemometer by pressing the power button; the anemometer defaults to
the 'VEL' measurement mode.
2. Hold the anemometer and align the plane of the fan blade perpendicular to the
direction of the airflow for measurement.
3. Read the displayed values on the screen, including wind speed, wind force level,
temperature, and humidity.
Note: Press the UNIT button to switch between corresponding units: Knots, km/h,
mph, m/s, ft/s, ft/min (6 units in total).
Airflow Measurement:
1. In the VEL mode, press the (VEL) button once to enter the FLOW mode for
airflow measurement.
2. Hold the anemometer and align the plane of the fan blade perpendicular to the
direction of the airflow for measurement.
3. Read the displayed values on the screen, including airflow, wind force level,
temperature, and humidity.
Note: Before measuring airflow, it is necessary to set the duct cross-sectional
area; otherwise, airflow measurement cannot be performed. In the airflow
measurement mode, press the UNIT button to switch between corresponding units: CMM,
CFM, CMS (3 units in total).
Duct Cross-sectional Area Setting:
1. In the powered-on state, long press the (VEL) button for more than 2
seconds to enter the AREA cross-sectional area setting mode.
2. Input the corresponding set value based on the actual cross-sectional area of
the measured duct. Press the UNIT button for increasing, press the HOLD button for
decreasing, and press the VEL button to move the setting position.
3. After setting is completed, long press the VEL button for more than 2 seconds
to exit the setting mode and start FLOW airflow measurement.
Disabling Auto Shutdown:
1. Power on the instrument normally by pressing the power button. The instrument
will automatically shut down after 15 minutes of inactivity.
2. After auto power-off, press the power button to restart.
3. Hold down the HOLD button and then press the power button for more than 2
seconds to power on. The instrument will emit 5 beeps, indicating the successful
cancellation of the auto shutdown function.
Note: Avoid strong vibrations, and do not touch the fan blades forcefully.
