Oscilloscope function

The oscilloscope mode is a complete intelligent measurement system, including signal input, data acquisition, data processing, automatic search and other functions. The waveform test bandwidth is 500 kHz. It uses a variable sampling rate to measure a slowly changing amount of signal. It is suitable for the measurement and observation of various signals in the vehicle circuit during the vehicle maintenance process, including the engine drive signal and engine power voltage of the new car, the ignition pulse signal of the motor vehicle engine, the camshaft signal, the crankshaft signal, the wheel speed sensor signal, the oxygen sensor signal, etc.

Vehicle circuit system detection
It can detect the low-voltage circuit of the car, indicate high voltage or leakage, and output the power supply voltage to test the parts on the car, or the voltage to operate the parts on the car, for example: B. Reduce light. It can also measure the battery voltage when the engine starts and determine whether the vehicle start system and the battery are in good condition.
