Притисните и држите Повер button (usually marked with a circle and vertical line symbol) to turn the device on or off.
4. Упутство за употребу
4.1 Општа навигација
- Користите Режим button to switch between Oscilloscope and Multimeter modes.
- The directional pad (up, down, left, right) is used to navigate menus and adjust parameters.
- Дугмад F1 да F4 correspond to on-screen menu options.
- Тхе Систем button accesses system settings.
- Тхе Сачувај button allows saving waveforms or measurement data.
4.2 Режим осцилоскопа
In Oscilloscope mode, the device displays real-time waveforms. Use the following controls:
- ЦХ1/2: Selects the active channel or displays both.
- HOR (Horizontal): Adjusts the time base (horizontal scale) of the waveform.
- Вертикална скала: Use the directional pad (up/down) to adjust the voltage scale for the selected channel.
- Trig/Δ (Trigger): Configures trigger settings (edge, level, mode) to stabilize the waveform display.
- Ауто: Automatically adjusts vertical, horizontal, and trigger settings for a stable waveform display.
- Пусти/паузирај: Freezes or resumes the waveform acquisition.
