The most important thing is to pay attention to safety in the process of using automobile testing equipment. The following are the instructions for the use of automobile testing equipment:

Meaning of each number: 0 is used to maintain the current waveform data, 1 is used to select the channel to display the waveform; 2 unit voltage value per small grid in the vertical direction; The unit time value of each square in the horizontal direction; 4. Potential baseline; 5. Signal selection; Waveform trigger type selection.

1. It is strictly prohibited to use the oscilloscope probe to directly detect the ignition high voltage signal to avoid damage to the oscilloscope.

2. Pay special attention to the power cord when moving the oscilloscope during the test.

3. The signal wire shall not touch the moving parts, to avoid the wire being twisted into the engine and causing accidents.
