3 overview

Waveform recorder is a comprehensive instrument that measures voltage and records electrical parameters: Its types can be divided into analog Waveform recorder and digital wave recorder: The analog waveform recorder uses an analog stylus to record measurements on a recording paper: Measured data: The digital waveform recorder stores the measured waveform data in the recorder: After recording, the recorded waveform and data can be called out: Waveform recorders are widely used in electricity, electronics, and traffic safety Industry fields such as monitoring and environmental monitoring:
