4. Instrucțiuni de utilizare

4.1. Modul Osciloscop

The oscilloscope function allows for the visualization and analysis of electrical signals over time.

1. Intrarea în modul Osciloscop: The device typically defaults to oscilloscope mode upon startup. If not, navigate to it via the MENU button.
2. Conectarea sondelor: Connect the oscilloscope probes to the CH1 and/or CH2 BNC connectors. Connect the ground clip of the probe to the circuit's ground.
3. Reglarea scalei verticale (Volți/Div): Use the navigation buttons to adjust the vertical sensitivity (V/div) for each channel (CH1, CH2) to fit the signal on the screen.
4. Ajustarea scalei orizontale (Timp/Div): Adjust the horizontal time base (s/div) to view the desired number of signal cycles.
5. Declanșarea:
   • Apăsați tasta TRIGGER button to access trigger settings.
   • Select trigger mode (Auto, Normal, Single) and trigger type (rising edge, falling edge).
   • Adjust the trigger level to stabilize the waveform.
6. Setare automată: Apăsați tasta AUTO button for automatic scaling and triggering of the input signal.
7. Masuri: Utilizați PRM (Parameter) button to display automatic measurements (e.g., Vpp, Vrms, Frequency).
8. Salvarea formelor de undă: Apăsați tasta SALVA button to capture the current waveform as a screenshot.

4.2. Modul multimetru

The multimeter function allows for precise measurement of various electrical parameters.

1. Intrarea în modul Multimetru: Navigate to multimeter mode via the MENU button.
2. Conectarea cablurilor de testare:
   • Pentru voltage, resistance, frequency, diode, and continuity: Connect the red lead to the VΩ-Hz jack and the black lead to the COM jack.
   • For current (mA): Connect the red lead to the mA jack and the black lead to the COM jack.
   • For high current (10A): Connect the red lead to the 10A jack and the black lead to the COM jack.
3. Selectarea funcției de măsurare: Use the navigation buttons to select the desired measurement function (e.g., DC Voltage, AC Voltage, Resistance, Capacitance, Diode Test, Continuity Test, Temperature).
