5. Setup

1. Power Connection: Connect the provided power cable to the AC power inlet on the rear panel of the oscilloscope and then to a suitable power outlet.
2. Power On: Press the power switch located on the front panel to turn on the oscilloscope.
3. Probe Connection: Connect the test probe to one of the analog input channels (CH1 or CH2) on the front panel. Ensure the probe's ground clip is securely connected to the ground of the circuit under test.
4. Probe Compensation: Before taking measurements, compensate the probe to ensure accurate readings. Connect the probe to the probe compensation output (usually a square wave signal) and adjust the probe's compensation trimmer until a flat-top square wave is displayed on the screen.

6. Operating Instructions

6.1 Basic Operation

• Channel Selection: Use the CH1/CH2 buttons to enable or disable channels and access their settings.
• Vertical Scale (VOLTS/DIV): Adjust the vertical scale using the dedicated knob for each channel to control the voltage per division displayed on the screen.
• Vertical Position: Use the vertical position knob to move the waveform up or down on the screen.
• Horizontal Scale (SEC/DIV): Adjust the horizontal scale knob to control the time per division, affecting the time base of the waveform.
• Horizontal Position: Use the horizontal position knob to move the waveform left or right on the screen.
• Trigger Level: Adjust the trigger level knob to stabilize the waveform display. The trigger point determines where the waveform capture begins.
• Auto Set: Press the 'AUTO SET' button for automatic adjustment of vertical, horizontal, and trigger settings to display a stable waveform.

6.2 Measurement Functions

The DSO2C10 offers a variety of measurement and analysis capabilities:

• Automatic Measurements: The device supports 32 types of automatic measurements, including maximum, minimum, peak-to-peak, frequency, period, rise time, fall time, and more. Access these via the 'MEASURE' menu.
• Cursor Measurements: Use horizontal and vertical cursors to manually measure voltage and time differences on the waveform.
• Digital Voltmeter (DVM): Features a 5-bit digital voltmeter and a 6-bit hardware frequency indicator for precise readings.
• Protocol Decoding: Supports decoding and analysis for RS232/UART, I2C, SPI, CAN, and LIN protocols.
• FFT Function: Perform Fast Fourier Transform (FFT) to analyze the frequency components of a signal.

6.3 Data Storage and Connectivity

• Save Data: The oscilloscope can save data in multiple formats, including settings, waveform data, reference waveforms, CSV files, and images. Use the 'SAVE TO USB' button for quick storage to a USB drive.
• USB Interface: Connect to a computer via the USB host/device interface for data transfer and remote control using SCPI commands.

7. Maintenance

• Cleaning: Clean the instrument's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and unplugged before cleaning.
• Ventilation: Keep the ventilation openings clear of dust and obstructions to ensure proper airflow and prevent overheating.
• Storage: When not in use, store the oscilloscope in a dry, dust-free environment away from direct sunlight and extreme temperatures.
• Calibration: Periodic calibration by qualified service personnel is recommended to maintain measurement accuracy.

8. Troubleshooting

This section provides solutions to common issues. For problems not listed here, please contact Hantek customer support.

• No Power: Ensure the power cable is securely connected to both the oscilloscope and the power outlet. Verify the power outlet is functional. Check the power switch position.
• No Waveform Display: Check if the input channel is enabled. Verify the probe is correctly connected and compensated. Adjust the vertical (VOLTS/DIV) and horizontal (SEC/DIV) scales. Use the 'AUTO SET' function. Ensure the trigger level is set appropriately.
• Unstable Waveform: Adjust the trigger level and trigger source. Check the trigger mode (e.g., Edge, Pulse). Ensure the input signal is within the oscilloscope's measurement range.
• Incorrect Measurements: Verify probe attenuation settings match the physical probe (1X, 10X, etc.). Perform probe compensation. Ensure the input coupling (AC/DC/GND) is appropriate for the signal being measured.
