To connect the TOPDON BT20 Wireless Battery Load Tester to your car's battery, follow these steps:
1. Before connecting the clamps to the terminals, use sandpaper to polish off any corrosion on the battery terminals to ensure accurate test values.
2. Attach the red clamp to the positive (+) terminal of the battery and connect the black clamp to the negative (-) terminal.
3. Make sure to keep the red and black clamps from touching each other.
4. Always disconnect the negative cable from the battery first and reconnect it last.
Once the clamps are properly connected, the battery tester will power on automatically and be ready to conduct tests.
