Performance & Highlights
⭐VDIAGTOOL V500 Pro MODE 1：
➤Oscilloscope Function: Oscilloscope mode provides real-time waveform display, helping users quickly identify issues like signal distortion, voltage spikes, and interference. It captures transient and repetitive faults that static tools may miss, and supports frequency analysis for precise debugging of oscillation, clock, or communication circuits.
➤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
➤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.
🚩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.
