3. Adjustable trigger horizontal position, which can be adjusted according to the instructions.
4. Observable previous trigger waveform, negative delay.
5. Waveform display can be fixed at any time with HOLD function.
How to Use:
1. Button function:
V/DIV: Sensitivity and vertical position selection.
SEC/DIV: Select time base and horizontal position.
TRIGGER: Select trigger mode, trigger level or trigger edge.
OK: Press once to enter the HOLD function, and press a second time to exit the HOLD function.
ADJ: Direction key, turn left and right to select parameters, and the selected parameters will be highlighted.
GND DC AC: The coupling can be switched to DC, AC or GND. When it is switched to GND, the oscilloscope input is disconnected from the external input and connected to the ground, that is, the input is 0V.
2. Function Operation:
Vertical Position Alignment: Switch to GND, long press V/DIV for 3 seconds.
Parameter Bar Opening or Closing: Press and hold the OK key for 3 seconds to open or close the parameter bar.
Save Waveform: Press OK and TRIGGER at the same time, and the current waveform will be saved in EEPROM. The original data will be replaced.
Read Waveform: Press OK and SEC/DIV at the same time t
