Commonly used automotive testing instruments
1, automotive multimeter
Automotive multimeter is mainly used to detect the strength of the DC current, DC voltage, AC voltage and wire resistance and other parameters, can also be used to detect the rotational speed, angle of closure, duty cycle (bandwidth), frequency, pressure, time, capacitance and other parameters. frequency, pressure, time, capacitance, inductance, semiconductor components and temperature.
2, pressure gauge
Pressure gauge is used to measure the container, piping and equipment within the gas or liquid pressure, is one of the automotive maintenance companies widely used instruments. Pressure gauge is generally by the range of the pressure gauge, connecting hose, one-way inlet valve and applicable to a variety of models of interchangeable joints and other components.
3, the test lamp
The test lamp is used to check whether the system power supply circuit to provide power to the electrical components, can be disconnected and short-circuit check, the commonly used type of 12V test lamp, self-powered test lamps and so on.
4, oscilloscope
Oscilloscopes are mainly used to trigger and collect signals (waveforms), scaling and positioning of waveforms, waveforms, etc., in automotive maintenance work, the detection of ignition systems, exhaust emissions analysis and parts quality, etc. useful. When using the oscilloscope, it may be necessary to come into contact with other parts of the system. To avoid potential hazards, special attention should be paid to the possibility of damage to the oscilloscope and its accessories from electrostatic discharge (ESD). To r prevent electrostatic discharge, wear an anti-static lap wrist strap to discharge your own static voltage when installing or removing sensitive components.
5, portable engine ECU tester
Portable engine ECU tester is mainly on the engine ECU parameters for dynamic testing, this test instrument is very easy to use, small size, light weight. The test instrument is generally equipped with a troubleshooting interface, only the diagnostic interface and engine compartment or instrument panel below the troubleshooting socket connected, and then operate the tester control panel key commands, you can test the engine electronic control system sensors, actuators and their circuits.
