VDIAGTOOL V500 PRO 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. By testing the relay’s coil voltage, resistance, contact status, etc., it is 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.
VDIAGTOOL V500 PRO MODE 1 Oscilloscope Function:
➤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 of the signal. For example, users can see if there is repeated noise interference or signal interruption, which helps to accurately locate the cause of the fault.
VDIAGTOOL V500 PRO MODE 1 0-5V POWER SUPPLY:
➤0-5V Power Supply provides a stable and adjustable low-voltage power supply for customers’ circuit diagnosis.
