Smart test
Automatically detect voltage and ohms
Smart testing generally refers to an automated and intelligent technology used to detect and analyze the health of the automotive circuit system, diagnose circuit faults, and give repair or adjustment suggestions. Such equipment usually integrates multiple sensors, algorithms, automatic detection programs, and user interfaces to diagnose automotive circuit problems quickly. It can reduce the time and complexity of manual inspections and improve maintenance efficiency.
Unlike traditional circuit testers, VDIAGTOOL V500 is an intelligent circuit probe tester that can automatically identify data such as voltage, resistance, current, etc. in the circuit, providing customers with great convenience in circuit diagnosis and improving your circuit diagnosis efficiency.
Multimeter mode
(voltage, resistance, diode short circuit, current, frequency)
Multimeter Mode is one of the common functions of automotive circuit intelligent testers or digital multimeters. It is used to measure multiple parameters of the circuit, such as voltage, current, resistance, etc. This mode is widely used in automotive maintenance, home appliance maintenance, electrical engineering and other fields. Specifically, the multimeter mode can help detect the health of the automotive circuit system, diagnose circuit problems, or perform basic electrical inspections.
VDIAGTOOL V500 power circuit probe diagnostic tool has a built-in multimeter mode. The multimeter integrates multiple functions and can measure DC voltage, AC voltage, resistance, current, etc., allowing users to quickly locate the fault point and make appropriate maintenance decisions.
Oscilloscope mode
Oscilloscope Mode is a function of an automotive circuit intelligent tester or digital oscilloscope that is used to capture, display, and analyze the waveform of an electrical signal that changes over time. It is widely used in automotive maintenance, electrical engineering, electronic product development, and other fields, and is particularly suitable for testing and analyzing signal quality and waveform characteristics in automotive electronic systems.
In automotive circuits, the main function of oscilloscope mode is to help maintenance personnel detect and analyze signals, sensor data, signal noise, etc. output by the electronic control unit (ECU), and diagnose whether the circuit is working properly. Compared with traditional multimeters, oscilloscopes can provide more detailed time domain analysis and identify transient problems that are not easy to detect.
Relay test
Relay testing is to check the function of the relay to ensure that it can work properly. Relay is a common electronic component in automotive circuits, mainly used for the transmission of switch control signals, such as controlling lights, air conditioning, electric windows, starting systems, etc. It usually consists of an electromagnet and a set of switch contacts. When current passes through the electromagnet, it generates a magnetic field, attracting the contacts to close, completing the connection or disconnection of the circuit.
In the automotive circuit intelligent tester, the relay test mode can help users determine whether the relay is working properly, and whether there are problems such as poor contact, coil disconnection, and contact damage.
VDIAGTOOL V500 circuit diagnostic kit supports relay tests. Relay tests can help customers detect key information such as relay switch status, coil health, contact performance, etc., to ensure the normal operation of the relay in the circuit, which plays an important role in improving the reliability and safety of the equipment and preventing circuit problems caused by relay failure.
Fuel injector testing and component activation
Fuel injector testing and component activation are very important operations in the automotive diagnostic and maintenance process to ensure that the fuel injection system can work properly. Fuel injectors are responsible for spraying fuel into the engine's combustion chamber in an atomized form to achieve effective combustion and power output. For modern vehicles, the normal operation of the fuel injection system is directly related to engine performance, fuel efficiency and emission control.
Injector testing and component activation provide efficient and direct diagnostic means to directly test the working status of key components without disassembly, provide real-time feedback, quickly locate faults, and verify the reliability of the control system. In addition, these two functions also support preventive maintenance, help optimize overall system performance, and avoid larger problems caused by component failure.
