◆The product adopts fuel pressure adjustment and control technology by microcomputer, which can
ensurestable fuel pressure and wide adjustable range. It is applicable to vehicles equipped with a variety of
gasoline injection systems. Meanwhile, the automation of injectors’ cleaning and testing processes can be
realized. 
◆ Thanks to the adoption of microcomputer automatic control and digital display technologies, the cleaning and testing processes can be controlled automatically and the parameters of the main status can be monitored in real time. 
◆Automatic fuel drain during a certain test can be realized via a routine, owing to the adoption of automatic fuel drain control technology. Start or [Stop] fuel drainage via the [Drain] button on the control panel in running or stop state. 
◆Adopting humanization design can make the system pressure fast restored to the default values.
 
It is an expert in injector solutions, featuring 11 injector-specific functions
01. Ultrasonic cleaning: It sends signals to the injectors through the pulse signal line, using the cleaning fluid with the ultrasonic vibration so as to completely remove the carbon and impurities inside the injectors.
02. Idle speed test (0-20ms): Simulate the engine idling speed and test the state of the fuel injector.
03. Medium speed test (0-7.5ms): simulate the engine running at medium speed and test the state of the fuel injector.
04. High-speed test (0-4ms): Simulate the high-speed performance of the engine and test the state of the fuel injector.
05. Acceleration test: Simulate the acceleration state of the car and test the performance of the fuel injector.
06. Shift speed test: Simulate the shifting state of the car and test the working performance of the fuel injector.
07. Leakage test: Test the sealing condition of the fuel injector.
08. Idle dpeed sprayability Test: Simulate the engine idling state and test the spraying performance of the fuel injector.
09. Medium speed sprayability test: Simulate the engine medium-speed state and test the spraying performance of the fuel injector.
10. High-speed sprayability test: Simulate the high-speed state of the engine and test the spraying performance of the fuel injector.
11. Main unit information: used to store the product number and date of manufacture of the product.

FAQ
1) The unit does not respond when the power is turned on.
Check the fuse on the lower right side of the unit and replace the fuse (5A) if it is damaged or broken.
 
2) Fuel distributor (rail) is leaking.
Check the o-ring and replace if damaged or broken. Do not tighten the adapter fitting too much,
otherwise, it may cause leakage.
 
3) When running, there is no working pressure.
When using a new machine for the first time, or if the machine has not been used for a long time, there may be no fuel
pressure. In this case, select the "first time use" function in the system functions, and then do the following:
a) Connect the test connector to the unit's fuel supply line and insert it into the fuel filler neck as shown in the illustration.
b) Then, run the first time use function.
c) When liquid comes out of the test connector, stop the operation. The device stops automatically after 30 seconds of operation.
 
4) There is no oil feed pressure, the buzzer sounds.
The machine has a lack of fuel warning function, when there is not enough fluid in the tank, the machine will beep, then
automatically shut down the fuel pump and injector nozzle, and return to the stop state. Add test fluid to the unit until the
buzzer stops beeping.
 
5) Completely emptying the test fluid from the glass tube requires pressing the Drain button several
times.
The solenoid valve will automatically stop after 15 seconds and will need to be emptied more times if more fluid is present.
Precautions
a) 1)Do not place anything on the control panel to prevent breaking the test measuring cup/glass panel.
b) 2) Do not disconnect the oil feed connection until the system pressure reaches "0" to prevent test fluid from spraying out.
c) 3) Always ensure that the unit is reliably earthed when in use.
d) 4) The device has a lack of oil alarm function. When the liquid level falls below the minimum line, the device will emit a warning
sound and at the same time automatically stop the oil pump and injector nozzle work. Until the test liquid is sufficient, the
equipment will be able to work normally.
e) 5) Clean the control panel in time, pulse signal line please ask stained test liquid, cleaning agent.
