Safety Precautions

Voltage Limitations

The Uberlogger is designed to operate with a 5V power supply only. Do not attempt to power the device with a voltage higher than 5V, as it may cause permanent damage to the device and void the warranty. The maximum voltage that the device can handle on the inputs is +/- 60V. Exceeding this voltage range may lead to unsafe situations to the user and may break the Uberlogger.

Temperature Range

The Uberlogger is suitable for use in environments with temperatures ranging from 10 °C to +50°C. Operating the device outside this temperature range may lead to inaccurate measurements or damage to internal components.

Storage Temperature

When not in use, store the Uberlogger in a dry, cool environment within the temperature range of 10°C to +40°C.

USB-C Connector

Use only the provided USB-C cable or compatible accessories to connect the Uberlogger to a USB-C port or a 5V power supply. Using non-certified cables may lead to electrical issues or malfunction.

Power Supply Current

Ensure the power supply used to power the Uberlogger provides a minimum current of 300mA. Using a power supply with lower current may result in unreliable performance or data loss.

Avoid Water Exposure

The Uberlogger is not water-resistant, so keep it away from liquids and moisture to prevent damage.

Secure Mounting

When using the Uberlogger, ensure it is securely mounted or positioned in a stable manner to prevent accidental falls or damage during operation.

Environmental Conditions

Operate the Uberlogger within the specified temperature range (15°C to +50°C) and avoid exposing it to extreme temperatures or environmental conditions that could affect its performance.

Proper Power Down

Always power off the Uberlogger properly before disconnecting it from the power source or USB-C port to prevent data corruption and ensure a safe shutdown.

Adherence to Local Regulations:

Comply with all relevant safety regulations, codes, and standards applicable in your area when using the Uberlogger.

By following these safety precautions, you can ensure the safe and reliable operation of the Uberlogger while utilizing its capabilities for precise voltage and temperature data acquisition in a wide range of environments and applications.
