6.2 Nettoyage

Wipe the exterior of the data logger with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the sensor openings.

6.3 Considérations environnementales

The MX1101 has an IP50 environmental rating, meaning it is protected against dust ingress but not against water. Operate and store the device within its specified temperature and humidity ranges to ensure optimal performance and longevity.

7. Dépannage

• Cannot connect to logger: Ensure Bluetooth is enabled on your mobile device and the logger is within the 100-foot wireless range. Check logger battery level.
• Logger not recording data: Verify that logging has been started via the HOBOmobile app. Check memory usage; if full, download data and clear memory.
• Lectures inexactes : Ensure the logger is placed in a location representative of the environment being monitored and not exposed to direct sunlight or drafts. Allow sufficient time for the logger to acclimate to new conditions.
• LCD blank or slow: This is normal if the ambient temperature is outside the 0 to 50°C (32 to 122°F) range. The logger continues to function, but the display may be affected.
• Autonomie courte de la batterie : Frequent connections, very short logging intervals, or continuous use of alarms can reduce battery life. Ensure fresh batteries are used.
