This digital circuit tester operates across a 12 to 24 V range to measure DC, AC, frequency, and resistance on both live and unloaded circuits. It supplies power and ground directly to components for functional testing while a self-resetting circuit breaker protects the tool from overloads. Dedicated modes for fuel injectors and PCM/ECM drivers provide specific diagnostic data on a multi-line color LCD screen.
