 In addition, V500 Pro supports 90° screen rotation, allowing customers to observe data parameters on the screen at any angle; the built-in flashlight design will enable customers to work normally in dark environments.

➤Multimeter mode: The multimeter in the VDIAGTOOL V500 Pro intelligent circuit probe detector is mainly used to measure basic parameters such as voltage, current, resistance, etc. in the circuit, and has a wide measurement range:
👉Voltage Test: 0.1-100V
👉Resistance Test: 0KR-200KR
👉Current Test：2mA-25A
👉Frequency Test: 10Hz-1MHZ
👉Oscilloscope:10Hz-100KHZ

🚩Practical design:

👉90° rotating screen: The main screen of  VDIAGTOOL V500 Pro circuit diagnostic tool can be rotated 90°. No matter from which angle, you can observe the circuit data on the screen 360° without blind spots so that you can focus on analyzing circuit faults.

👉Built-in flashlight: The V500 PRO has a built-in flashlight, which makes it convenient to perform circuit diagnosis in dark environments.

🔍MODE 1 Relay Test

➤Relay testing is the process of checking the function and performance of a relay to ensure that it works properly in the circuit. Testing the relay's coil voltage, resistance, contact status, etc. Makes it possible to diagnose whether the relay is damaged or failed, which is crucial to maintaining the reliability and safety of the electrical system. Common relay tests include:
👉 Voltage test
👉 Coil resistance test
👉 Relay action test
👉 Relay delay and retention test.

📈MODE 1 Oscilloscope Function (10Hz–100kHz)

➤Parameter range：
👉Frequency Measurement Range: 10Hz-1000Khz
👉Waveform display: 10Hz-100Khz

➤Oscilloscope Function:
✔️Visual fault diagnosis: The oscilloscope mode visualizes the signal and intuitively displays the change of the signal shape, which makes it convenient for customers to quickly identify abnormal behavior in the circuit, such as waveform distortion, signal attenuation, and other problems.

✔️Detect transient problems: Transient problems in the circuit (such as instantaneous voltage spikes, pulse interference, etc.) are sometimes not captured by static measurement tools (such as multimeters). The oscilloscope can display these transient signals in real-time, which helps to find transient faults, such as power supply fluctuations or unstable signals.

✔️Frequency analysis: The oscilloscope can not only display the waveform of voltage or current but also help users measure the frequency, period, and other characteristics of the signal. This is very useful for debugging and optimizing oscillation circuits, clock circuits， or wireless communication circuits, helping customers accurately diagnose the frequency characteristics of the circuit.

✔️Capture repetitive faults: For periodic faults, the oscilloscope can find the problem by capturing and analyzing the periodic changes. For example, users can see if there is repeated noise interference or signal interruption, which helps to accurately locate the cause of the fault.

💥MODE 1 Component Activation & Injector Test

➤Component Activation: Component activation is mainly used by circuit testers to confirm and test the function and status of each component in the circuit. By activating different components, users can quickly identify faults and ensure the normal operation of the circuit. This provides customers with practical conveniences such as saving time, improving maintenance efficiency, and reducing unnecessary replacement costs.

➤Injector Test: Injector testing is often used to detect the performance and working status of automotive injectors. Through testing, the injection frequency, injection volume, and injection pattern of the injector can be evaluated to ensure that it can accurately supply fuel when the engine is running.

There are 4 modes for injector testing:
👉Mode 1: One 250-millisecond positive electrode
👉Mode 2: Cycle positive for 7 milliseconds, negative for 20 milliseconds in 1.4 seconds
👉Mode 3: Cycle the positive electrode for 4 milliseconds and the negative electrode for 10 milliseconds in 1.4 seconds
👉Mode 4: Continuous output of positive pole for 7 milliseconds and negative pole for 20 milliseconds

➤Through injector testing, customers can bring the following conveniences:
👉Fault diagnosis: quickly identify injector problems, such as blockage, uneven injection amount, injector leakage, etc., to reduce troubleshooting time.
👉Performance optimization: ensure the normal operation of the injector, and improve engine efficiency and power output.
👉Cost savings: avoid unnecessary injector replacement and reduce repair and maintenance costs.

✔️Convenient debugging and testing: As an analog signal source, users can easily adjust the output voltage for various circuit tests and debug, quickly verify the impact of different voltage inputs on the circuit, and improve the efficiency of troubleshooting.
✔️High safety: Compared with high-voltage power supplies, 0-5V power supplies are suitable for sensitive electronic components, reducing the risk during the test process, avoiding accidental application of excessive voltage and damage to the equipment, and improving the safety of use.

⚙️MODE 2 Breaker Finder

When the VDIAGTOOL V500 Pro 2-in-1 Car Power Circuit Probe Kit Breaker Finder Tester switches to mode 2, it is equivalent to V210, with 3 test methods:

✔️Locate Open Circuits:
Open Wire Detector instantly detects and alerts you to open circuits. Easily locate short circuits, broken wires, open connections, current leaks, and trace wires. Transmitter and receiver LEDs indicate open or short circuit conditions.

✔️Wire Tracing:
Easy to use by just simply connecting the transmitter in series with the circuit or wire under test, (i.e.: in place of a blown fuse, across a connector, in series with an open wire, a light bulb socket, etc.), and scanning the circuit/wire with the tracers flexible probe to find the trouble spot.

✔️ Check Short Circuits (Switch to MODE 1 to use resistance measurement）
Automotive Short Circuit Finder allows you to identify intermittent circuit problems by flexing wires or connectors and listening for changes in the receiver tone. This automotive circuit finder has a 6.7-inch flexible probe that can help reach wires in congested places.
