6-IN-1 Multimeter & Oscilloscope Function

VDIAGTOOL 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.

ONE-CLICK Smart Test & Quick Polarity Test

VDIAGTOOL V500 intelligent power circuit tester automatically measures voltage, resistance, and polarity without switching modes. Just turn it on and start testing.
Touch the negative terminal, and the green LED lights up with a beep.
Touch the positive terminal, and the red LED turns on.

Component Activation & Sensor/Signal Circuit Test

VDIAGTOOL V500 automotive circuit tester activates vehicle components such as lights, motors, wipers, radiator fans, relays, and fuel injectors. Three activation modes are available: Momentary (short test), Latch (continuous output), and Pulse (simulated signal).

VDIAGTOOL V500 also tests sensors and signal circuits. This allows checking voltage, continuity, and wiring, helping technicians quickly pinpoint the root cause of electrical problems.

Relay/Fuse/Trailer Light Test & Bad Fuses Location

VDIAGTOOL V500 is more than just a power circuit probe — it's your all-in-one relay, fuse, and trailer light tester.V500 helps you diagnose faults faster, safer, and more accurately — keeping your vehicle always ready for the road.

🔸 Relay Test: Quickly check whether 4-pin or 5-pin relays are working properly. Helps you identify faulty relays in seconds and ensures your electrical system functions safely.

🔸 Fuse Test: Locate blown fuses instantly without removing them one by one. Save time and avoid vehicle breakdowns caused by hidden fuse failures.

🔸 Trailer Light Test: Easily test trailer lights and wiring connections to ensure they are working perfectly before hitting the road — no more surprises during your trip.
