3. セットアップ

3.1デバイスの充電

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 プローブとリードの接続

  • オシロスコーププローブ: 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.
  • マルチメーターのテストリード: 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 電源のオン/オフ

を押し続けます button (usually marked with a circle and vertical line symbol) to turn the device on or off.

4. 操作手順

4.1一般的なナビゲーション

  • 使用 モード button to switch between Oscilloscope and Multimeter modes.
  • The directional pad (up, down, left, right) is used to navigate menus and adjust parameters.
  • ボタン F1F4 correspond to on-screen menu options.
  • システム button accesses system settings.
  • 保存 button allows saving waveforms or measurement data.

4.2 オシロスコープモード

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.
  • 垂直スケール: 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.
  • 自動: Automatically adjusts vertical, horizontal, and trigger settings for a stable waveform display.
  • 再生/一時停止: Freezes or resumes the waveform acquisition.

4.3 マルチメーターモード

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.

  • 巻tage 測定値 (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.
  • 抵抗測定(Ω): Connect leads across the component when power is off.
  • 導通/ダイオード: For checking circuit continuity or diode function.
  • 静電容量測定(F): Connect leads across the capacitor when power is off.
