If your master can not work or broken,please to check your smart box

If your master can not work or broken,please to check your smart box,and then know which part is broken,you do not need to send back all machine to us,only buy a spare part to replace it.Good help for you!Can save money for you!

Launch x431 master smart box major functions involve the simulation and test for all sensors on vehicles. Under simulation conditions, it can receive the control signal from X-431 main unit and carry out all the commands. Under test conditions, it can transfer the data back to the main unit in accordance with the control signal given by the main unit.

Under test condition, the latest data can be recorded in the form of curve. This puts the change of the test data right in front of your eyes and is highly significant for process analysis. In particular, it is good for the capture of remittent changes in the process.

Under voltage simulation condition, the user will be able to make any change to the voltage under simulation by dragging the icon indicating the voltage. This enables the simulation of any imaginable voltage change and gives more flexible and more accurate sensor simulation.

The full range of sensor parameters makes it possible to retrieve data in different ways. By presetting simulation and test range under all conditions, accurate and reliable performance can be resulted.

Powered by vehicle battery, SensorBox is widely adaptable to voltage change within the range of 8-28 volts. With the design of separated power circuits, measurement under all conditions can be made without removing the sensors from the vehicle. At the same time, the accessory adaptors give great convenience for the switching and testing of all the sensors.

The safety considerations in the design have given the launch x431 SensorBox as well as the sensors under test perfect protection
