5. Opsætning
5.1 Opladning af enheden
Connect the provided USB Type-C cable to the device's USB port (labeled 3 in Image 4.1) and to a standard USB power adapter (not included) or a computer USB port. The battery indicator on the screen will show charging status.
5.2 Tænd/sluk
To power on the device, long press the power button (labeled 6 in Image 4.1). To power off, long press the same button until the screen turns off.
5.3 Initial Mode Selection
Upon powering on, the device may default to the last used mode. Use the MODE button (labeled 9 in Image 4.1) to switch between Oscilloscope, Multimeter, and Signal Generator modes.
6. Driftstilstande
6.1 Oscilloskoptilstand
In Oscilloscope mode, the device displays real-time waveforms. Connect the oscilloscope probes to the dual channel input (labeled 1 in Image 4.1) and to the circuit under test.
- Vertikal følsomhed: Adjust using the menu buttons (F1-F4) or navigation wheel to set Volts/Div.
- Tidsbase: Adjust using the menu buttons (F1-F4) or navigation wheel to set Time/Div.
- Trigger Function: Select Auto, Normal, or Single trigger modes. Adjust trigger level to stabilize the waveform.
- Automatisk måling: Press the AUTO button (labeled 7 in Image 4.1) for automatic waveform parameter measurements.
