⑤Press"CH1"，can view the values and configuration（configuration has default）
⑥Waveform display can be adjusted based on their own through the vertical volts /
division and trigger ways to meet your needs（Time base, vertical volts / division and
other specific operations, please refer to the operation of general oscilloscope）
2）Gasoline and diesel fuel nozzle
①Same as Electromagnetic valve step 1
②After entering the main menu interface select "Actuator" ， then enter the
sub-menu press the up and down keys to select " Gasoline and diesel fuel nozzle "，
press "OK" button, after confirmation, entering oscilloscope operation interface
③Connect the probe to CH1 and probe set to 10X，then connect grounding clip to
the signal ground or grounding.
④Since the "Gasoline and diesel fuel nozzle" Function of oscilloscope has default
settings （ Probe 10X ， time base 1ms ） ,simply connect the probe to the
corresponding signal can display waveform.
⑤Press"CH1"，can view the values and configuration（configuration has default）
⑥Waveform display can be adjusted based on their own through the vertical volts /
division and trigger ways to meet your needs（Time base, vertical volts / division
and other specific operations, please refer to the operation of general oscilloscope）
Note: there is a rectangular concave on waveform, the width of the rectangle is the
actual fuel injection pulse width, after the engine entering the closed-loop control,
fuel injection pulse width is generally 1.5ms-2.9ms. If bigger than this value, there
are clogging or excessive intake and other issues of nozzle.
3） Gasoline nozzle (Current)
①Same as Electromagnetic valve step 1
