3. Einrichtung
3.1 Aufladen des Geräts
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 Anschluss von Sonden und Leitungen
- Oszilloskop-Tastköpfe: 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-Messleitungen: 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 Ein-/Ausschalten
Halten Sie die Leistung button (usually marked with a circle and vertical line symbol) to turn the device on or off.
4. Bedienungsanleitung
4.1 Allgemeine Navigation
- Verwenden Sie die Modus button to switch between Oscilloscope and Multimeter modes.
- The directional pad (up, down, left, right) is used to navigate menus and adjust parameters.
- Schaltflächen F1 Zu F4 correspond to on-screen menu options.
- Der System button accesses system settings.
- Der Speichern button allows saving waveforms or measurement data.
4.2 Oszilloskopmodus
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.
- Vertikale Skala: 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.
- Abspielen/Pause: Freezes or resumes the waveform acquisition.
4.3 Multimeter-Modus
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.
- Bandtage Messung (V): Schließen Sie die Leitungen parallel zum Stromkreis an.
- Current Measurement (A/mA): Connect leads in series with the circuit. Ensure correct jack selection (A or mA) based on expected current.
- Widerstandsmessung (Ω): Connect leads across the component when power is off.
- Durchgangs-/Diode: For checking circuit continuity or diode function.
- Kapazitätsmessung (F): Connect leads across the capacitor when power is off.
5. Wartung
5.1 Reinigung
Wischen Sie die Außenseite des Geräts mit einem weichen, fusselfreien Tuch ab.amp 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.
