Operating Instructions

The La Crosse Technology T83745 is a passive device that provides continuous readings without requiring power. Once mounted, it will immediately begin displaying temperature and humidity.

• Reading Temperature: The red liquid column in the vertical tube indicates the current temperature in degrees Fahrenheit. Read the value corresponding to the top of the red column against the Fahrenheit scale.
• Reading Humidity: The needle on the circular dial at the bottom indicates the current relative humidity as a percentage (%RH).
• Key Storage: To store or retrieve keys, carefully remove the unit from its mounting point, access the compartment on the back, and then remount the unit.

Maintenance

• Cleaning: To clean the device, wipe it gently with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the plastic casing or the display.
• Weather Protection: While designed to be weatherproof, prolonged exposure to extreme weather conditions (e.g., heavy rain, direct intense sunlight, freezing temperatures) can affect its lifespan and accuracy. Positioning it in a sheltered location is recommended.
• Calibration: This unit is factory-calibrated and does not offer user-adjustable calibration.

Troubleshooting

Inaccurate Readings:

If you suspect inaccurate temperature or humidity readings:

• Check Placement: Ensure the device is not in direct sunlight, which can artificially inflate temperature readings. Also, avoid placing it near heat sources (e.g., vents, appliances) or sources of moisture.
• Environmental Factors: Extreme weather conditions or rapid changes in environment can temporarily affect readings. Allow the device to stabilize in its location for at least 30 minutes.
• Physical Damage: Inspect the thermometer tube and hygrometer dial for any visible damage.

Difficulty Reading Scale:

Ensure the device is mounted at eye level and in a well-lit area for optimal visibility.
