All-in-One Power Probe Circuit Tester for Serious Electrical Diagnostics
Unlock next-level vehicle diagnostics with the VDIAGTOOL V500, a professional-grade 6-in-1 tester built to handle all your automotive electrical troubleshooting needs—from fuel injectors to relays, from sensor signals to blown fuses.
The V500 combines oscilloscope, multimeter, relay tester, and power circuit probe into one device. It covers AC/DC voltage, diode, resistance, current, frequency, polarity, and more—eliminating the need for multiple tools.
Visualize voltage and signal behavior in real time. With 4 waveform arguments—voltage, resistance, frequency, and duty cycle—you’ll quickly identify sensor and actuator faults.
Deliver 4 adjustable pulse modes to test injectors directly (0–260V support). Efficiently check injector performance and maximize cleaning effects with fuel system cleaners—no trip to the shop needed.
Simulate real-world working conditions to activate lights, relays, motors, fans, wipers, injectors, and more using 3 signal modes: Momentary, Latch, and Pulse—ideal for pinpointing faulty components.
Quickly test 4-pin and 5-pin vehicle relays and locate blown fuses in seconds. Also check trailer light functionality before your next road trip—helping prevent unexpected electrical failures.
The intelligent tester auto-detects voltage, resistance, and polarity in a single step—saving time and reducing guesswork. Red/Green LED indicators and buzzer provide immediate polarity feedback.
Features a 90° foldable color screen for confined spaces, integrated flashlight for dark work areas, and online updates with support for 9 languages—perfect for technicians and DIYers alike.
