3. Persediaan
3.1 Mengecas Peranti
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 Menyambung Prob dan Plumbum
- Probe Osiloskop: 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.
- Multimeter Test Leads: 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 Menghidupkan/Mematikan
Tekan dan tahan butang kuasa button (usually marked with a circle and vertical line symbol) to turn the device on or off.
4. Arahan Operasi
4.1 Navigasi Umum
- Gunakan Mod button to switch between Oscilloscope and Multimeter modes.
- The directional pad (up, down, left, right) is used to navigate menus and adjust parameters.
- Butang F1 kepada F4 correspond to on-screen menu options.
- The Sistem button accesses system settings.
- The Jimat button allows saving waveforms or measurement data.
4.2 Mod Osiloskop
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.
- Skala Menegak: 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.
- Main/Jeda: Freezes or resumes the waveform acquisition.
4.3 Mod Multimeter
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.
- Pengukuran Rintangan (Ω): Connect leads across the component when power is off.
- Continuity/Diode: For checking circuit continuity or diode function.
- Pengukuran Kapasitans (F): Connect leads across the capacitor when power is off.
