The 7-inch (800x480 pixels) color LCD provides a clear and detailed display of waveforms and measurement parameters. The display grid is 8x12, offering ample space for waveform visualization.

5. Setup

5.1 Power Connection

1. Ensure the oscilloscope's power switch is in the OFF position.
2. Connect the provided power cord to the power input socket on the side of the oscilloscope.
3. Plug the other end of the power cord into a grounded AC power outlet (100V-240V AC, 50/60Hz).

5.2 Probe Connection

1. Connect the BNC connector of the oscilloscope probe to the CH1 or CH2 input connector on the front panel.
2. Ensure the probe is securely twisted into place.
3. Attach the probe ground clip to a known ground point in your circuit.
4. Set the probe attenuation switch (usually on the probe itself) to the desired setting (e.g., 1X or 10X). Remember to match this setting in the oscilloscope's channel menu for accurate readings.

5.3 Initial Power On

After connecting power and probes, press the power button on the front panel to turn on the oscilloscope. The device will perform a self-test and display the main waveform interface.

6. Operating Instructions

6.1 Basic Waveform Display

Use the vertical (VOLTS/DIV) and horizontal (SEC/DIV) knobs to adjust the scale of the displayed waveform. The position knobs allow you to move the waveform vertically and horizontally on the screen.
