Three measurement modes - Automatic: automatic triggering will collect and refresh waveform records in real time, and will not retain the waveform - Normal: when the amplitude of the collected signal reaches the set trigger level value, the trigger system will lock the waveform and keep it displayed on the screen. The oscilloscope is still collecting. When it is triggered again, the waveform on the screen will be updated to the current waveform again, which is a continuous trigger - Single: when the amplitude of the collected signal reaches the set trigger level value, the trigger system will lock the waveform and keep it displayed on the screen. When the waveform acquisition is completed, the STOP state is displayed, and the oscilloscope stops signal acquisition; if you need to trigger again, press HOLD to cancel STOP and enter the waiting trigger state 21. TYPE-C data cable connects to the DC 5V output adapter for charging 22. Long press for 2 seconds to turn on and off, short press to enter relative value measurement 23. The screen uses a 2.8-inch IPS full-view color screen 24.
