A fast car is a convenient means of transportation. Therefore, everyone should pay attention to its safety performance. If an abnormality is found during driving, the car detection tool should be used to detect it in time, find the problem as soon as possible and deal with it to ensure the safety of the car.Comprehensive diagnostic equipment for vehicle off-lineWhat are they?

1. Jumper wire

Jumper wires are a simple and reliable vehicle inspection tool. When used, the wires will be "bonded" to the circuit suspected of being faulty, thereby connecting it and testing the conductivity of the circuit. If the circuit works properly when the jumper wire is used and does not work without the jumper wire, it means that there is a circuit fault within the "jumping" range. The fault can be solved through patient inspection and treatment.

2. Test light

Test lights are vehicle inspection tools that can be divided into two types: active and passive. They can be used to measure voltage. To use them for fault detection, one of the wires can be grounded, and then the circuit voltage at any point on the other wire can be connected. If the light is on, it means there is voltage at the test point and the circuit tested by the test light is complete; otherwise, there is a problem in the circuit that needs to be further eliminated.

3. Digital multimeter

Digital multimeter is one of the commonly used automotive testing tools. It can accurately test electronic circuits with much higher accuracy than analog meters. Nowadays, digital multimeters have been widely used in electrical fault diagnosis and testing for automotive fault detection. They can accurately test some sensitive components of automotive circuits without damaging or changing their circuits.

These are the most commonly used comprehensive diagnostic equipment for whole vehicle off-line. In addition, there are many professional testing tools, which I will not introduce one by one here. The purpose of using testing tools is to find the location and cause of automobile faults. We should know which product's automobile testing tools are good and buy high-quality testing tools from manufacturers with product guarantees.
