2. Safety Instructions

Always adhere to the following safety guidelines to prevent electric shock, fire, or damage to the device.

• Power Supply: 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.
• Environment: Operate the device in a dry, well-ventilated area. Avoid exposure to moisture, extreme temperatures, or direct sunlight.
• Ventilation: Do not block ventilation openings. Adequate airflow is essential to prevent overheating.
• Grounding: The oscilloscope must be properly grounded. Do not defeat the grounding plug.
• Input Voltage: The device is rated for CAT II 300 V. Do not apply voltages exceeding this rating to any input terminal.
• Servicing: Refer all servicing to qualified service personnel. Do not attempt to open or repair the device yourself.
• Cleaning: Disconnect the power before cleaning. Use a soft, dry cloth. Do not use liquid cleaners or aerosols.

4. Setup

4.1 Unpacking and Inspection

1. Carefully remove the oscilloscope from its packaging.
2. Inspect the device for any signs of physical damage that may have occurred during transit.
3. Verify that all included accessories, such as the power cord and user manual, are present.

4.2 Power Connection

1. Ensure the power switch on the oscilloscope is in the OFF position.
2. Connect the provided power cord to the power input on the rear panel of the oscilloscope.
3. 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 Initial Power-On

1. After connecting the power, switch the oscilloscope ON.
2. Observe the display for initial power-up sequence and self-test indicators.
3. Allow a few moments for the device to stabilize before proceeding with measurements.

5. Operating Instructions

5.1 Basic Controls

• Power Switch: 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):
  • AC: Blocks the DC component of the signal, allowing only the AC component to be displayed.
  • DC: Displays both AC and DC components of the signal.
  • GND: Disconnects the input signal and grounds the input, useful for setting the zero reference level.
• CH1/CH2 Inputs: 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 Triggering

Triggering stabilizes the waveform on the display. The VC 630-2 features high-sensitivity triggering.

• Level: Adjusts the voltage level at which the trigger occurs.
• Slope: Selects whether the trigger occurs on the rising or falling edge of the signal.
• Source: Selects the trigger source (e.g., CH1, CH2, External).

5.5 Advanced Functions

• 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. Maintenance

6.1 Cleaning

To maintain the performance and appearance of your oscilloscope:

• Always disconnect the power cord before cleaning.
• Use a soft, dry, lint-free cloth to wipe the exterior surfaces.
• For stubborn dirt, slightly 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 Storage

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 Calibration

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)".
