2.2 Device irinše
The following image illustrates the main components of the OWON HDS25 device:
The device features a central 3.5-inch LCD screen for waveform display and measurement readings. Below the screen are function buttons (F1-F4), mode selection buttons (Mode, CH1/2, HOR, System, Save, Auto, Trig/Δ, Power, Play/Pause), and a directional pad for navigation. At the bottom, there are input jacks for current (A, mA), common ground (COM), and voltage/resistance/capacitance (VΩ+C) measurements.

In Oscilloscope mode, the device displays real-time waveforms. Use the following controls:
- CH1/2: Selects the active channel or displays both.
- HOR (Horizontal): Adjusts the time base (horizontal scale) of the waveform.
- Vertical Scale: 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.
- Laifọwọyi: Automatically adjusts vertical, horizontal, and trigger settings for a stable waveform display.
- Ṣiṣẹ/Daduro: Freezes or resumes the waveform acquisition.
4.3 Multimeter Ipo
