It can read maximum/minimum voltage, frequency, and duty cycle. Oscilloscope mode provides five signal monitoring functions: camshaft, crankshaft, injector, throttle signal, and CAN bus polarity detection.
  • 【Component Activation + Dual Protection】The ECT300 tester activates automotive components via probes to verify operation of lights, motors, wipers, cooling fans, relays, injectors, and more. Its dual protection system guards against overcurrent and overheating with millisecond response times, effectively preventing short-circuit damage.
