【OSCILLOSCOPE & MULTIMETER】The KM601 super probe tester has two powerful testing modes: oscilloscope and multimeter. Oscilloscope function tests various voltage signals with four features: DC voltage, AC voltage, frequency, and duty cycle. The last three include waveform display modes. The multimeter module measures resistance and diode forward voltage, with a continuity test that alerts the user if resistance is below 30 ohms, indicating a wire break
【FUEL INJECTOR TEST & RELAY TEST】This versatile electrical system circuit tester not only tests fuel injectors with injector signal parameters—ensuring optimal cleaning with car cleaner—but also features a relay test function. The relay testing module assesses cables, ground wires, and probes to help identify if vehicle relays are functioning correctly. It is designed to test the most common 4-pin and 5-pin relays found in vehicles. Say goodbye to being stranded at night due to burnt-out light relays or losing power during your road trip
【BATTERY TEST】One of the biggest advantages of this power scan circuit tester is its ability to check the battery; it acts like a battery tester but offers so much more! It includes three key functions: battery test, battery cranking test, and battery charging test. It provides precise and quick assessments of battery health, voltage, and charge status, allow users to assess the overall condition and performance of the car battery effectively
【TRAILER LIGHT TEST & BAD FUSES LOCATION】Have you ever faced frustrating situations like a trailer light malfunction during a road trip or a blown fuse that leaves your vehicle stranded? Our automotive probe circuit kit is here to help! Quickly check if your trailer lights are working. And if you've ever been stuck trying to locate a blown fuse, our probe tester identifies faulty fuses in seconds, making repairs a breeze
