1. Test Continuity
2. Test Voltage Polarity
3. Check continuity of switches, relays and diodes, fuses and circuits
4. Test the polarity of cables and plugs
5. Track and locate short circuits
6. Poor test ground
7. Working voltage: 6-24V DC
8. Cable length: about 5m
9. Overload protection: 8A (when the current exceeds 8A, the current will be automatically disconnected)
