Multi-function Auto Circuit Tester(
battery not include

With the increasing technical updates, the unceasing development of auto industry and the continuous renewal of auto parts and electronic components,
auto circuits gradually increase, but the detection tools of maintenance telephone are very few. Jiaxun automobile circuit tester excludes difficulties and
anxieties for vast auto repair factories, 4S shops and auto headquarters.
1. It can accurately detect various line faults under the situation of no damage to rubber cover.
2. It sets multimeter & test lamp gear which has the functions that the top-level multimeter fails to do. It specially detects the wires with bad contact and aging wires.
3. It can detect each fault in the place where the space is narrow and light is weak.
* 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. All ranges are 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 Gear
1. Connect the alligator clip of black test pen to the ground, turn the knob switch to the voltage measurement gear, use the feeler to hook the detected rubber cover wire,
press down trigger, and head the probe against the front detected rubber cover wire. In case of any power in wire, LCD will naturally display accurate voltage in wire. (0V-6V DC voltage can be measured).
2. Press function switch key (SELECT), LCD will display alternating current symbol (AC) to measure 0V-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 inconvenient and easy to hurt hands. You can accurately detect the control or signal wires that
you 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 “V–“, use the feeler to hook the detected rubber cover wire, press down trigger,
and head 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 less than 10V” indicates that the back end of the wire has bad contact or is aged.
Light-emitting Diode (LED 1) Test Lamp
1. Connect the alligator clip of black test pen to the ground, turn the knob switch to the light-emitting diode (LED1) test lamp gear,
use the feeler to hook the detected rubber cover wire, press down trigger, and head the probe against the front detected rubber cover wire. In case of any power in wire, LED will be on.
2. Short-circuit and open-circuit test of auto circuits.
3. Test of ignition system
4. Test of generator
5. Test of charging system
6. Test of input and output signal of sensor
7. Test of executive component signal
8. Especially applicable to the test of pulse signal: oil injection nozzle and vehicle speed sensor
Resistance Measurement Gear
1. Turn the knob switch to the resistance () gear, and connect positive and negative test pens to two ends of resistance on circuit board to accurately measure the resistance value.
2. Press function switch key (SELECT), LCD will display LED symbol () to detect diode and triode.
3. Press function switch key (SELECT) twice continuously, LCD will display buzzer symbol (), and use positive and negative pens to detect on/off.
Test Lamp Gear()
1. Connect the alligator clip of black test pen to the ground, turn the knob switch to the test lamp () gear, use the feeler to hook the detected rubber cover wire,
press down trigger, and head the probe against the front detected rubber cover wire. If the wire has 12V power, the test lamp will be on.
2. Test short-circuit and open-circuit of automobile circuits.
3. Especially applicable to low-voltage current conduction.
Operation Drawing in Narrow Space
1. In narrow place where your body fails to enter for operation, the surrounding parts must be removed if you use general tools (multimeter or test lamp).
2. In the place where the space is narrow or light is weak, the instrument detects as usual, because the forefront of the product has feeler. Without high-brightness (LED) lighting lamp,
it can detect faults without removal of any parts, which saves time and effort.
Nighttime Operation
Automobile circuits are often repaired at night and in the place where the light is weak. The operation is very troublesome if general tool is used.
But the instrument can detect without other lighting facilities and also can be used as flashlight.
Press (BLCTR3) switch for 3s, LCD super-brightness LED backlight will be on, and backlight is intelligent and will be closed automatically after 30s.
Technical Field:

The patented invention is used for the detection of automobile circuit faults, with efficiency, accuracy, convenience, reliability and other practical applicability.
Technical Features:
At present, there are two modes for the detection of automobile circuit: one is to detect automobile circuit with conventional multimeter.
Under the situation of automobile circuit with bad contact or aging wires, the test results are normal but fail to describe accurate and actual faults.
It has great limitation during actual use. The other is to detect automobile circuit with test lamp, the traditional tool fails to measure line voltage,
because its operation time is long, it is not easy to operate in too narrow place, moreover, the probe easily pricks hands, and it is very inconvenient to operate in winter or at night.
The tester with good rubber cover can accurately detect the fault location of automobile circuit. The set multi-functional gears can be used for the detection of multiple faults.
Furthermore, you can operate it at your will in dark and narrow place. Without other lighting facilities, it is safe, convenient and efficient to use.
It is applicable to each maintenance environment. Therefore, it is a good assistant of automobile decorations and circuit repairing
