Enhanced protection mechanisms guard against reverse polarity on input signal lines, excessive input voltage, and overloaded current, ensuring safer and more convenient operation.\u003c\/li\u003e\r\n \u003cli\u003eSimple and Intuitive InterfaceThe CP20 automotive power circuit probe tester supports full-vehicle electrical system testing from 080V. After powering on, it cycles between two advanced modes: 1 Multimeter and oscilloscope combination mode, 2 Component activation mode. Equipped with a 2.4-inch high-definition color screen, LED indicators, a buzzer, and high-sensitivity probes, test processes and results are displayed in real-time on the TFT screen for clear and intuitive visualization.\u003c\/li\u003e\r\n \u003cli\u003eMultimeter + Oscilloscope ModeIn multimeter mode, this tester supports six functions: voltage, resistance, diode, continuity (ON\/OFF), polarity (P-N), and frequency testing. 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.\u003c\/li\u003e\r\n \u003cli\u003eComponent Activation + Dual ProtectionThe 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.\u003c\/li\u003e\r\n \u003cli\u003eMulti-Language Long Cable After-Sales SupportThis tool supports 12 languages (including English, German, French, Japanese, etc.), features a 16-foot cable with LED illumination and audible alarm, and is compatible with 080V vehicle electrical systems. Suitable for cars, trucks, boats, excavators, motorcycles, and more, it's widely used in repair shops, education, home, and industrial settings.
