3. Podešavanje
3.1 Punjenje uređaja
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 Spajanje sondi i elektroda
- 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.
- Ispitni kablovi za multimetar: 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 Uključivanje/isključivanje
Pritisnite i držite Snaga button (usually marked with a circle and vertical line symbol) to turn the device on or off.
4. Uputstvo za upotrebu
4.1 Opća navigacija
- Koristite Mode button to switch between Oscilloscope and Multimeter modes.
- The directional pad (up, down, left, right) is used to navigate menus and adjust parameters.
- Dugmad F1 to F4 correspond to on-screen menu options.
- The Sistem button accesses system settings.
- The Sačuvaj button allows saving waveforms or measurement data.
4.2 Režim 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.
- Auto: Automatically adjusts vertical, horizontal, and trigger settings for a stable waveform display.
- Pusti/pauza: Freezes or resumes the waveform acquisition.
4.3 Režim 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.
- VoltagMjerenje (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.
- Mjerenje otpora (Ω): Connect leads across the component when power is off.
- Continuity/Diode: For checking circuit continuity or diode function.
- Mjerenje kapacitivnosti (F): Connect leads across the capacitor when power is off.
