4. Operating Instructions
4.1 Measurement Functions
The HP-866B can measure the following environmental parameters:
- Wind Speed
- Ambient Temperature
- Wind Chill Indication (when temperature is below 0°C)
- Humidity
- Dew Point
- Barometric Pressure
- Altitude
4.2 Taking Measurements
When the wind vane (impeller) turns, the LCD will instantly display the wind speed and temperature. For other measurements like humidity, dew point, barometer, and altimeter, the device will display these automatically.
4.3 Unit Settings
To change the wind speed unit:
- Press the 'UNIT' button (labeled '2' in Figure 4) repeatedly. The unit will cycle through m/s, Km/h, Ft/min, Knots, and mph.
4.4 Max/Min/Average Readings
- Max/Min: Press the 'MAX/MIN' button (labeled '3' in Figure 4) to display the maximum or minimum recorded values.
- Average: Press the 'AVG' button (labeled '6' in Figure 4) to display the average reading over a 15-second period.
4.5 Backlight Function
- Press the backlight button (labeled '4' in Figure 4) to turn the backlight on.
- Press it again to turn the backlight off. The backlight will automatically turn off after 15 seconds of inactivity.
4.6 Temperature Unit Switch
- Press the '°F/°C' button (labeled '5' in Figure 4) to switch between Celsius and Fahrenheit temperature units.
4.7 Low Battery Warning
A low battery symbol will appear on the LCD when the batteries need to be replaced.
5. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: When not in use for extended periods, remove the batteries to prevent leakage. Store the device in a cool, dry place within the specified storage temperature range (-40°C to 60°C).
- Impeller Care: Ensure the wind vane (impeller) is free from obstructions and rotates smoothly for accurate readings.
6. Troubleshooting
- Device not turning on: Check battery installation and ensure batteries are fresh.
- Inaccurate readings: Ensure the impeller is clean and unobstructed. Verify that the device is held correctly and not influenced by external factors (e.g., body heat affecting temperature readings).
- Display issues: If the display is dim or flickering, replace the batteries.

8. User Tips
- For the most accurate wind speed readings, ensure the anemometer is held upright and the impeller is facing directly into the wind.
- Avoid blocking the sensors with your hands or other objects during measurement.
- When measuring temperature, allow a few moments for the sensor to stabilize to the ambient conditions.
- The backlight is useful in low-light conditions but consumes more battery power. Use it judiciously.
- Keep the device clean and dry to ensure longevity and accurate performance.
