Auto repair tool test signal of sensor Automobile Circuit Detector

Automobile Circuit Detector   With the insreasing technical updates, the unceasing development of auto industry and the continuous renewal of auto parts and electronic components, auto circuits gradually increasing, but the detection tools of maintenance telephone are very few. Jiaxun automobile circuit tester excludes diffcelties and anxieties for vast auto repair factories, 4S shops and auto headquarters. Features It can acctually detect various line faults under the situation of no damage torubbercover. It sets multimeter&test lamp gear which has the functions that the top-level multimeter fails to do. It specially detects the wire with bad contact and aging wires. It can detect each fault in the place where the space is narrow and light is weak.   Advantage The product is the only four-in-one product with the functions of multimeter, test lamp, lighting lamp and probe. All functions of digital multimeter are intelligent.Backlight is closed automatically after the backlight of 30s. Allrangesare intelligent, and the instrument shuts off automatically after the stop of use for 20min. It is convenient to use, efficient to detect, easy to operate and has reliable performance.     Voltage measurement Connect the alligator clip of black test pen to the ground, turn the knop switch to the voltage measurement gear, use the feeler to hook the detected rubber cover wire, press down trigger, and heat the probe against the front detected rubber cover wire. In case of any power in wire, LCD will natually display accurate voltage in wire.(0V-6V DC voltage can be measured). Press function switch key(SELECT), LCD will display alternating current symbol(AC) to measure0V-380V AC voltage.   Installation and operation of Electric Appliances for decorations   For the decorations of auto electric appliances, many control wires or signal wires must be searched, if you use general tools(multimeter or test lamp), rubber cover must be damaged for searching, which is convenient and easy to hurt hands. You can accurately detect the control or signal wires that yo need under the situation of no damage to rubber cover, as long as you hook the detected wire with this tool and press down trigger, which is convenient and efficient.   Test Lamp & Multimeter Voltage Gear   The gear especially detects the wires with bad contact or aging wires, Before test, connect the alligator clip of black test pen to the ground, turn the knob switch to the test lamp & multimeter voltage gear, use the feeler to hook the probe against the front detected rubber cover wire. If the front end of the detected wire is 12V(normal voltage), and then measure the voltage of back end of the wire, if LCD displays the voltage of back end of the wire, if LCD displays the voltage less than 10V indicates that the back end of the wire has bad contact or is aged.   Resistance Measurement Gear Turn the knob switch to the resistance gear, and connect positive and negative test pens to two ends of resistance on circuit board to acctually measure the resistance value. Press function switch key(SELECT), LCD will display LED symbol to detect diode and triode. Press function switch key (SELEC) twice continuously, LCD will display buzzer symbol, and negative pens to detect on/off.   Light-emitting Diode(LED1) Testlamp   Test Lamp Gear   Test Lamp Gear
