• LIGHT Button: Activates or deactivates the LCD backlight for improved visibility in low-light conditions.

4.2 Taking Measurements

1. Press the LED button to power on the anemometer.
2. Ensure the impeller is unobstructed and facing the direction of the wind or air flow you wish to measure.
3. The current wind speed will be displayed on the LCD.
4. Press the UNIT / DOWN button to cycle through different measurement units as desired.
5. To view minimum, maximum, or average readings, use the UP / MIN / MAX or VEL / AVG buttons.
6. To hold a reading on the screen, press the SET / HOLD button. Press again to release.
7. After use, press the LED button to power off the device.

5. Maintenance

Proper maintenance ensures the longevity and accuracy of your anemometer.

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the impeller is free of dust and debris.
• Storage: When not in use for extended periods, remove the battery to prevent leakage. Store the anemometer in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery Replacement: Replace the 9V battery when the low battery indicator appears on the display or if the device fails to power on.
• Impeller Care: Avoid dropping the device or subjecting the impeller to impact, as this can damage the sensitive sensor.

6. Troubleshooting

If you encounter issues with your MS6252A Anemometer, refer to the following common problems and solutions:

• Device does not power on:
  • Check if the 9V battery is installed correctly with the right polarity.
  • Replace the battery with a new one.
• Inaccurate readings:
  • Ensure the impeller is clean and rotates freely without obstruction.
  • Verify that the anemometer is positioned correctly in the airflow.
  • Check for strong electromagnetic interference in the measurement area.
• Display is dim or flickering:
  • The battery may be low. Replace the 9V battery.
  • Ensure the backlight is not continuously on, which can drain the battery faster.
