3. Nastavení
3.1 Nabíjení zařízení
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 Connecting Probes and Leads
- Osciloskopické sondy: 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.
- Měřicí kabely multimetru: 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 Zapnutí/vypnutí
Stiskněte a podržte Moc button (usually marked with a circle and vertical line symbol) to turn the device on or off.
4. Návod k obsluze
4.1 Obecná navigace
- Použijte Režim button to switch between Oscilloscope and Multimeter modes.
- The directional pad (up, down, left, right) is used to navigate menus and adjust parameters.
- Tlačítka F1 na F4 correspond to on-screen menu options.
- The Systém button accesses system settings.
- The Uložit button allows saving waveforms or measurement data.
4.2 Režim osciloskopu
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.
- Přehrát/pozastavit: Freezes or resumes the waveform acquisition.
4.3 Režim multimetru
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.
- svtagMěření e (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.
- Měření odporu (Ω): Connect leads across the component when power is off.
- Continuity/Diode: For checking circuit continuity or diode function.
- Měření kapacity (F): Connect leads across the capacitor when power is off.
5. Údržba
5.1 Čištění
Wipe the device exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected from all power sources and measurement circuits before cleaning.
