1)test injecting angle, atomization, dribbling and automatic testing and cleaning Press auto key. The pump start to work automatically, after work over, the pump turn off automatically, the injector keep injecting for 15s, the time valve decrease to 0, can observe the injecting angles, atomization and volume, replace or clean the injector, if appears gush, unusual angels and unusual volume, stop injecting for 30s, and observe injecting volume, time value shows 30s, the liquid will back to the fuel tank in the following 30s, then start dribbling testing for 60s, if no dribbling, the unit will starts regular testing automatically. 2)test mode at idling speed Conduct the injecting test as follows: Injecting rpm: 1600r/min Pulse width: 2.2ms Count: 3000 Timing: 112s When the producer is over, observe the injecting uniformity, and replace or clean it if the volume over 9% 3)test mode at maximum loading Conduct the injecting test as following: Injecting rpm: 4000r/min Pulse width 2.8ms Count 3000 This program can observe the injecting volume at the maximum loading 4)test mode at high speed Conduct the injecting test as following: Injecting rpm: 6500r/min Pulse width 2.5ms Count 4000 Timing 36s This program can observe the working state at the high speed. 5)test injecting with complete procedure During this procedure pulse width is 2.2ms, rpm is 1600r/min, then the rpm will up to 9975r/min, pulse width will up from 3ms to 12ms, then down to 1.1ms.Total cycle is 5 times, and running time is 20s, observe for 30s after the test, then the liquid will return for 30s. During the automatic test, press selection to pause it as you need. 53.5*48.5*55.5
