3.3 Įjungimas / išjungimas
Paspauskite ir palaikykite Galia button (usually marked with a circle and vertical line symbol) to turn the device on or off.
4. Naudojimo instrukcijos
4.1 Bendroji navigacija
- Naudokite Režimas button to switch between Oscilloscope and Multimeter modes.
- The directional pad (up, down, left, right) is used to navigate menus and adjust parameters.
- Mygtukai F1 į F4 correspond to on-screen menu options.
- The Sistema button accesses system settings.
- The Išsaugoti button allows saving waveforms or measurement data.
4.2 Osciloskopo režimas
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.
- Auto: Automatically adjusts vertical, horizontal, and trigger settings for a stable waveform display.
- Leisti / pristabdyti: Freezes or resumes the waveform acquisition.
4.3 Multimetro režimas
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.
- ttage 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.
- Varžos matavimas (Ω): Connect leads across the component when power is off.
- Continuity/Diode: For checking circuit continuity or diode function.
- Talpos matavimas (F): Connect leads across the capacitor when power is off.
