6. Operating Instructions

6.1 Power On/Off

• To turn on: Press the Power button once.
• To turn off: Press the Power button once.
• The device will automatically power off after 10 minutes of inactivity.

6.2 Unit Selection

The anemometer can display measurements in various units:

• Air Velocity: m/s, km/h, ft/min, knots, mph. Use the UNIT button to cycle through these options.
• Airflow: CFM (Cubic Feet per Minute) or CMM (Cubic Meters per Minute).
• Temperature: Celsius (℃) or Fahrenheit (℉). Use the ℃/℉ button to switch between units.

6.3 Backlight Function

To activate or deactivate the display backlight:

• Press the LIGHT button.
• The backlight will automatically turn off after 7 seconds of inactivity to save power.

6.4 MAX/MIN/AVG Readings

The anemometer can record and display maximum, minimum, and average values:

• Press the MAX/MIN button to cycle through Maximum, Minimum, and Average readings for air velocity and airflow.
• The device also supports 2/3 Max readings.

6.5 Telescopic Probe Usage

The telescopic probe allows for measurements in confined or elevated spaces:

• Extend the telescopic rod to the desired length (up to 1.08m).
• The probe tip can be bent to adjust the angle for optimal measurement.
• Ensure the probe is positioned correctly in the airflow path for accurate readings.

7. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the anemometer in its protective case in a cool, dry place when not in use. Remove batteries if storing for extended periods to prevent leakage.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display to ensure accurate operation.
• Probe Care: Handle the telescopic probe with care. Avoid excessive force when extending, retracting, or bending the tip.

8. Troubleshooting

• Device not turning on: Check battery installation and ensure batteries are not depleted. Replace if necessary.
• Inaccurate readings: Ensure the probe is correctly positioned in the airflow. Check for any obstructions to the sensor. Verify that the correct measurement units are selected.
• Display not visible: Activate the backlight function. If the issue persists, check battery level.
