cell phone jammer is highly portable

Automotive multimeter measuring resistance, voltage, current outside, but also measurement speed, frequency, temperature, capacitance, dwell angle, duty cycle and other projects, and automatic vehicle multimeter ordinary digital multimeter commonly used tool: the role of manual vacuum pump: role: they said hand-held vacuum measuring instrument. Used for evacuating the vacuum in the engine control system. Generally with the vacuum degree of vacuum gauge, a variety of connection hoses and connectors and other accessories. Note: Note: check the vacuum hose connection to prevent vacuum leakage caused by the measurement inaccurate. The examination must be required to be seized components exert a vacuum degree of the imposition of a vacuum through the General Assembly damage components. Common tools: fuel pressure gauge effects: the role of: a special tool used to measure the fuel pressure of the fuel supply system.cell phone jammer is highly portable. Note: Note that the range and the measured system pressure range compatible fuel pressure gauge. The two commonly used instruments: the injector cleaning portable fuel injector cleaning devices fixed injector cleaning instrument oil cooler drip inspection and without having to remove and easy to use. All to Penpen oil checking generally used to clean the fuel injector. Commonly used instruments: the failure diagnostic apparatus, also known as computer decoder. Sub-dedicated general-purpose special-and general-purpose dedicated general-purpose two. Function to read or clear fault codes. Dynamic testing of the engine control system, display of instantaneous information, and provide the basis for the diagnosis. Action directive issued to the executive component of the electronic control system, in order to check the status of implementation of the components.
Car circuit diagram to identify common sense: the characteristics of the vehicle circuit car circuit diagram can help to quickly find the location of the installation of the electronic control system components, the fault lines in order to check, can avoid the maintenance process in line error connection. Car circuit is divided into: Line drawings, wiring diagrams, circuit schematics. Common features: dual-supply of automotive electrical wiring, low DC voltage; single wire; connected in parallel; negative ground; basically the same layout.The leather cover will makecell phone jammer more convenient to carry.  Car circuit diagram to identify the common sense: car circuit in the line color markings and symbols commonly used different colors, different number of wires to identify the electrical circuit. Domestic automobile electrical wiring and the main color and color-coded as follows: the main color of the line type of power line ignition and start the exterior lighting line of line headlamps, fog lamps, turn signal and light signal line air defense lamps and interior lighting line instrumentation, alarm signal and Auxiliary electrical wiring of the electric horn line radio, clock, cigarette lighter, etc.
