Setup
Battery Installation
The BT-8806 Anemometer requires batteries for operation. To install:
- Locate the battery compartment cover on the back of the device.
- Use the included screwdriver to open the battery compartment.
- Insert the required batteries (not included) according to the polarity markings (+/-) inside the compartment.
- Securely close the battery compartment cover.
Attaching Lanyard
Attach the included lanyard to the designated loop on the anemometer for secure handling and to prevent accidental drops.
Tripod Mounting
For stable, hands-free operation, the device features a standard tripod screw mount at its base. Attach it to a compatible tripod as needed.
Operation
Power On/Off
Press and hold the Power button (red circle with line) for approximately 2 seconds to turn the device on or off.
Backlight Control
Briefly press the Power button to activate or deactivate the display backlight for improved visibility in low-light conditions.
Wind Speed Measurement
Hold the anemometer so that the wind cup sensor at the top faces the airflow. The current wind speed will be displayed prominently on the LCD.
Changing Wind Speed Units
Press the UNIT button to cycle through the available wind speed units: meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), and Knots.
Temperature Measurement
The current ambient temperature is displayed at the bottom section of the LCD simultaneously with wind speed readings.
Changing Temperature Units
Press the °F/°C button to switch the temperature display between Celsius (°C) and Fahrenheit (°F).
MAX/MIN/AVG Function
Press the MAX/MIN button to view the maximum, minimum, and average wind speed readings recorded since the device was powered on or the function was reset. Press the button repeatedly to cycle through these modes.
Data Hold Function
Press the HOLD button to freeze the current readings on the display. This is useful for noting down measurements. Press the button again to release the hold and resume real-time measurements.
Maintenance
Cleaning
Wipe the device exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water.
Storage
When not in use for extended periods, store the anemometer in a cool, dry place. Remove the batteries to prevent leakage and damage to the device.
Troubleshooting
- Device does not power on: Check battery installation. Ensure batteries are inserted with correct polarity and are not depleted. Replace batteries if necessary.
- Inaccurate wind speed readings: Ensure the wind cup sensor is unobstructed and rotating freely. Avoid measuring in turbulent or obstructed airflow.
- Display is blank or shows erratic readings: Check battery level. If the issue persists after replacing batteries, contact customer support.
- Backlight not working: Ensure the device is powered on. Briefly press the Power button to toggle the backlight.
