1. Testing and cleaning the injecting state of 4/6/8 injectors separately or at the same time. 2. Auto, semi-auto, manual testing and programme testing fuction, 3. Spraying angle, dribbling, atomizing and volume uniformity, shortest period and work pressure of on-and-off testing, etc. 4. Testing range: RPM 0-9950R/Min, impulse width 0-20ms, counting 0-9999; all kinds of testing programs to select. 5. Injector protection: with exclusive automatic device to regulate the current and voltage to ensure the test of high or low voltaic and impedance injectors. 6. Tesingt mode: with many testing mode,such as random changing value setting, initating engine running,signal feedback of the loading,random pause/continue during test, timing/counting mode with high precision. 7. Memory program setting: memory the state of automatically going slow. 8. Flash orientation testing: directionally test injecting angle and atomizing state by the flash gun.
