Installation and Maintenance

Installation Requirements

1. Fix the equipment in a stable environment to avoid vibration and high temperature.
2. Ensure good contact when connecting the power supply and battery test interface, and follow electrical safety specifications (grounding treatment).
3. Ensure the installation space meets heat dissipation requirements (to avoid overheating).

Maintenance Operations

1. Regularly check the cleanliness of test clips and interfaces to prevent increased contact resistance.
2. Analyze historical data through software to identify battery degradation trends in advance.
3. Conduct timely troubleshooting after a fault alarm; replace modules if necessary or contact technical support.
4. Regularly calibrate test accuracy (it is recommended to follow the official manual).

Precautions

1. Power off the equipment during maintenance to avoid electric shock risks.
2. Use official tools for software updates to ensure compatibility.
