Precautions For Electrical Inspections

Precautions for Electrical Inspections




- When using electrical test equipment, insert the probe of the tester into the wire side of the connector. Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector.




- Use a U-shaped probe. Do not insert the probe forcibly.
- Use specified service connectors in troubleshooting. Using improper tools could cause an error in inspection due to poor metal-to-metal contact.
