2. Istruzioni di sicurezza
Always adhere to the following safety guidelines to prevent electric shock, fire, or damage to the device.
- Alimentazione elettrica: Ensure the oscilloscope is connected to a power source matching the specified voltage (115 V/AC or 230 V/AC). Use only the provided power cord.
- Ambiente: Utilizzare il dispositivo in un luogo asciutto e ben ventilato. Evitare l'esposizione a umidità, temperature estreme o luce solare diretta.
- Ventilazione: Non ostruire le aperture di ventilazione. Un flusso d'aria adeguato è essenziale per evitare il surriscaldamento.
- Messa a terra: The oscilloscope must be properly grounded. Do not defeat the grounding plug.
- Ingresso volumetage: The device is rated for CAT II 300 V. Do not apply voltages exceeding this rating to any input terminal.
- Manutenzione: Per qualsiasi intervento di assistenza, rivolgersi a personale qualificato. Non tentare di aprire o riparare il dispositivo da soli.
- Pulizia: Scollegare l'alimentazione prima di pulire. Utilizzare un panno morbido e asciutto. Non utilizzare detergenti liquidi o spray.

4. Impostazione
4.1 Disimballaggio e ispezione
- Carefully remove the oscilloscope from its packaging.
- Inspect the device for any signs of physical damage that may have occurred during transit.
- Verify that all included accessories, such as the power cord and user manual, are present.
4.2 Collegamento di alimentazione
- Ensure the power switch on the oscilloscope is in the OFF position.
- Connect the provided power cord to the power input on the rear panel of the oscilloscope.
- Plug the other end of the power cord into a grounded electrical outlet that supplies either 115 V/AC or 230 V/AC, as appropriate for your region.
4.3 Accensione iniziale
- After connecting the power, switch the oscilloscope ON.
- Observe the display for initial power-up sequence and self-test indicators.
- Allow a few moments for the device to stabilize before proceeding with measurements.
5. Istruzioni per l'uso
5.1 Controlli di base
- Interruttore di alimentazione: Located on the front panel, used to turn the device ON/OFF.
- Intensity/Focus: Adjusts the brightness and sharpness of the trace on the screen.
- Position (Vertical/Horizontal): Moves the waveform vertically or horizontally on the display.
5.2 Vertical Deflection (VOLTS/DIV)
The VOLTS/DIV knob controls the vertical sensitivity of the input signal. It ranges from 5 mV/Div to 5 V/Div. Select the appropriate setting based on the amplitude of the signal you are measuring.
- Input Coupling (AC/DC/GND):
- Corrente alternata: Blocks the DC component of the signal, allowing only the AC component to be displayed.
- CC: Displays both AC and DC components of the signal.
- TERRA: Disconnects the input signal and grounds the input, useful for setting the zero reference level.
- Ingressi CH1/CH2: Connect your probes to the BNC connectors for Channel 1 and Channel 2.
5.3 Horizontal Sweep (TIME/DIV)
The TIME/DIV knob controls the horizontal sweep speed, determining how much time each horizontal division represents. Adjust this to view the desired number of cycles of your waveform.
5.4 Innesco
Triggering stabilizes the waveform on the display. The VC 630-2 features high-sensitivity triggering.
- Livello: Regola il volumetagil livello in cui si verifica l'innesco.
- Pendenza: Selects whether the trigger occurs on the rising or falling edge of the signal.
- Fonte: Selects the trigger source (e.g., CH1, CH2, External).
5.5 Funzioni avanzate
- X-Y Operation: Allows the oscilloscope to display one input signal against another, useful for Lissajous figures and phase measurements.
- Z-Input: Modulates the intensity of the trace, often used for blanking or brightening specific parts of the waveform.
- Phase Meter: Utilize this function for precise phase difference measurements between two signals.
- 50 Ω Output: An additional 50 Ω output is provided for connecting external frequency counters, enhancing the versatility of the oscilloscope.
6. Manutenzione
6.1 Pulizia
Per mantenere le prestazioni e l'aspetto del tuo oscilloscopio:
- Scollegare sempre il cavo di alimentazione prima della pulizia.
- Per pulire le superfici esterne, utilizzare un panno morbido, asciutto e privo di lanugine.
- Per sporco ostinato, leggermente dampen the cloth with water or a mild, non-abrasive cleaner. Do not allow any liquids to enter the device.
- Avoid using harsh chemicals, solvents, or abrasive cleaning agents.
6.2 Conservazione
When not in use, store the oscilloscope in a cool, dry place, away from direct sunlight, dust, and extreme temperatures. Protect it from physical shocks.
6.3 Calibrazione
The Voltcraft VC 630-2 is factory calibrated. For continued accuracy, periodic professional calibration may be required depending on usage and application. Please note that the product description indicates "factory (without certificate)".
