Product Details
✓【ALL-IN-ONE AUTOMOTIVE ELECTRICAL DIAGNOSTIC TOOL】 — Upgrade your troubleshooting with the V500 power circuit probe tester, combining a Circuit Tester, Short Circuit Finder, Multimeter, Oscilloscope, Relay Tester, Component Activator and Fuel Injector Tester in one tool. Designed for 9–30V automotive electrical systems, it helps DIYers and technicians quickly find wiring, power, ground, relay, fuse, sensor and actuator problems without switching between multiple testers. If the product you received is not in brand-new condition or is missing accessories, please request a replacement-support @ vdiagtool
✓【6-IN-1 MULTIMETER & OSCILLOSCOPE FUNCTION】V500 circuit probe tester works more powerfully than others. Multimeter mode contains voltage(VDC), resistance(OHM), diode(DIO), current(AMP), frequency & polarity(P-N). The oscilloscope function features clear real-time waveform diagrams to test various voltage signals with 4 arguments: AC/DC voltage, resistance value & frequency duty cycle, making it advanced for detecting sensors & actuators, circuit connectivity & bad grounds.
✓【RELAY/FUSE/TRAILER LIGHT TEST & BAD FUSES LOCATION】V500 is also a relay tester that will assess cables, ground wires & probes to quickly detect whether relays are normal. Suitable for the most common 4-pin and 5-pin relays found in vehicles. Besides, it will help you locate a blown fuse in seconds and check if the trailer light is in good condition. In favor of avoiding frustrating situations like a trailer light malfunction during a road trip or a blown fuse that leaves the vehicle stranded.
✓【COMPONENT ACTIVATION & SENSOR/SIGNAL CIRCUIT TEST】V500 automotive power circuit probe tester supports activating components to judge their condition high-efficiently. It will generate activation signals in 3 activation modes: MOMENT, LACH & PULSE to the components, such as car lights, motors, windshield wipers, radiator fans, relays, fuel injectors, & other on/off-board electric equipment to pinpoint the root cause of electrical issues, also allowing testing various sensors & signal circuits.
✓【FUEL INJECTOR TEST】This electrical system probe tester provides 4 types of pulse signals (once or multiple times) to the injector for quick and easy diagnosis of the Injector circuit, supporting tests ranging from 0-110V to 260V for most injector models. It is more convenient for the owner to detect the condition of the fuel injector regularly and achieve the maximum cleaning effect with car cleaner, undoubtedly saving time & costly trips to a dealership!
✓【ONE-CLICK SMART TEST & QUICK POLARITY TEST】Without switching between different test modes, this intelligent power circuit probe tester Kit could measure voltage, resistance, and positive/negative polarity automatically at one time while turned on. If the probe tip connects to the negative terminal, the Green LED lights on with buzzing. Red LED lights on while it is positive polarity. Note: Any issues with the item please feel free contact us via vdiagtool2 @ outl ook c om for 24/7 support!
✓【UPGRADE AUTOMOTIVE CIRCUIT TESTER】This is the latest generation of electrical system tester to help you troubleshoot all sorts of automotive electrical/electronic problems efficiently. With clear result display in waveform & digital, LED lights & buzzer alarm for quick polarity identification, 90° foldable screen for displaying data in narrow area & flashlights to better illumination in dark, online updates & 9 languages available, it must be a great choice for DIYers, electricians & technicians.
