- AUTOMATED RELAY TESTING: Performs automatic testing on common 4 and 5 pin relays by cycling each relay through multiple test sequences to confirm functional operation without manual steps
- GOOD BAD INDICATION: Clearly identifies relay condition with a simple pass or fail result when any test cycle is unsuccessful, helping quickly determine whether replacement is required
- OFF VEHICLE DIAGNOSTICS: Allows quick and convenient relay testing away from the vehicle, reducing troubleshooting time and eliminating guesswork during electrical diagnostics
- VEHICLE POWERED OPERATION: Operates using a standard 12V vehicle battery connection, eliminating the need for standalone power sources or internal batteries
- RESISTANCE DETECTION: Loads switch contacts during testing to help identify excessive resistance that may cause intermittent electrical issues in real world applications
