Circuit Tester Guide
A circuit probe tester is a tool used to detect and diagnose circuits. We have the following products: V200, V200pro, V210, V500, V500 Pro.
VDIAGTOOL V210
VDIAGTOOL V210 Automotive Open and Short Detector Circuit Tester is powered by 2 9V batteries, it can easily locate breaker points, open connections, broken wires, leakage (tone change), and even trace wires/cables without damaging the insulation. For DIY enthusiasts, electricians and technicians, it is a convenient and efficient circuit instrument that can simply and quickly determine the continuity of cables/wires and diagnose breaker points.
VDIAGTOOL V200
VDIAGTOOL V200 Power Circuit Probe Tester is a simple but extremely useful circuit tester with a 20ft + 20ft extension cord for checking if a car circuit or a component is powered. It supports ✔Tracing wires ✔AC/DC voltage tests ✔Diode, resistance tests ✔Polarity tests ✔Continuity, ground, signal circuit tests ✔Activating components ✔Relay, fuse, trailer light tests ✔Locate shorts ✔Circuit breaker protection for all electrical systems of 12-24V vehicles.

You can quickly and easily find shorts, open connections, broken wires, current leaks and even trace wires. Save yourself time and costly trips to the dealer by purchasing this must-have circuit tester today.
If you are already impressed with the performance of our VDIAGTOOL V200 Pro Automotive Power Circuit Probe Tester, we now bring you an even more versatile solution — the VDIAGTOOL V200 Pro Upgrade Kit.
Unlike the standard V200 Pro, this upgraded version comes with a 30PCS Back Probe Kit designed for harness connectors, automotive sensors, and fuel injectors. The kit includes:
15 × Back Probe Pins (stainless steel, 0.07mm needle, supports testing up to 30V)
5 × Banana Plug to Alligator Clip Circuit Test Wires
5 × Wire Piercing Probes
5 × Nickel-Plated Copper Alligator Clips
With 3 different probe angles (90°, 135°, Straight), the back probe lead set allows you to access tight or angled connectors with ease, meeting various daily diagnostic needs.

VDIAGTOOL V500
VDIAGTOOL V500 is an intelligent circuit system probe tester that covers all circuit tests:
1. Smart test
2. Multimeter mode (voltage, resistance, diode & short circuit, current, frequency)
3. Relay protection test
4. Oscilloscope mode
5. Injector test
6. 0-5V power supply
7. Component activation
8. Positive and negative detection
