2.2 Komponente naprave
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.

2.3 Priloženi dodatki
- USB Type-C kabel
- Oscilloscope Probes (2)
- Probe Adjustment Tool
- Merilni kabli za multimeter
- Zaščitna torba

3. Nastavitev
3.1 Polnjenje naprave
Before initial use, fully charge the device using the provided USB Type-C cable and a compatible power adapter (not included). The charging indicator on the device will show the charging status.
3.2 Priključitev sond in vodnikov
- Osciloskopske sonde: Connect the BNC connector of the oscilloscope probes to the CH1 and CH2 input ports on the top of the device. Ensure a secure connection.
- Merilni kabli multimetra: For multimeter functions, insert the red test lead into the VΩ+C jack and the black test lead into the COM jack. For current measurements, use the A or mA jacks as appropriate.
3.3 Vklop/izklop
Pritisnite in držite Moč button (usually marked with a circle and vertical line symbol) to turn the device on or off.
4. Navodila za uporabo
4.1 Splošna navigacija
- Uporabite Način button to switch between Oscilloscope and Multimeter modes.
- The directional pad (up, down, left, right) is used to navigate menus and adjust parameters.
- Gumbi F1 do F4 correspond to on-screen menu options.
- The Sistem button accesses system settings.
- The Shrani button allows saving waveforms or measurement data.
4.2 Način osciloskopa
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.
- Samodejno: Automatically adjusts vertical, horizontal, and trigger settings for a stable waveform display.
- Predvajanje/pavza: Freezes or resumes the waveform acquisition.
4.3 Način multimetra
In Multimeter mode, the device functions as a digital multimeter. Use the directional pad to select the desired measurement function (Voltage, Current, Resistance, etc.). Ensure the test leads are connected to the correct input jacks for the selected measurement type.
- voltage Measurement (V): Connect leads in parallel with the circuit.
- Current Measurement (A/mA): Connect leads in series with the circuit. Ensure correct jack selection (A or mA) based on expected current.
- Merjenje upornosti (Ω): Connect leads across the component when power is off.
- Continuity/Diode: For checking circuit continuity or diode function.
- Merjenje kapacitivnosti (F): Connect leads across the capacitor when power is off.
5. Vzdrževanje
