4. Operating Instructions
4.1 User Interface: Touchscreen and Knobs
The MHO14 Series supports hybrid operation, allowing control via its 8-inch touchscreen or physical knobs and buttons. Use the touchscreen for intuitive gestures like pinch-to-zoom and swipe, and the knobs for precise adjustments of vertical scale, horizontal scale, and position.
4.2 Basic Oscilloscope Functions
- Channel Selection: Use the CH1, CH2, CH3, CH4 buttons to enable/disable channels and access their settings.
- Vertical Scale & Position: Use the dedicated 'Vertical' knobs to adjust the voltage scale (V/div) and vertical position of each channel.
- Horizontal Scale & Position: Use the 'Horizontal' knobs to adjust the time base (s/div) and horizontal position. The 'Zoom' knob allows for detailed inspection of waveforms.
- Trigger Settings: The 'Trigger' section allows you to set the trigger type (e.g., Edge), level, and source channel. Press 'Auto' for automatic trigger setup.
- Auto Set: Press the 'Auto Set' button for automatic waveform display and scaling.
- Run/Stop: Use the 'Run/Stop' button to start or pause waveform acquisition.
4.3 Multimeter Operation
To use the integrated multimeter, switch to DMM mode (Digital Multimeter). Connect the test leads to the COM and appropriate input (VΩ, mA, or A). Select the desired measurement type (voltage, current, resistance, continuity, diode, capacitance) from the on-screen menu.
4.4 Advanced Functions
- Math Functions: Access the 'Math' menu to perform operations like addition, subtraction, multiplication, division, integration, differentiation, and FFT (Fast Fourier Transform).
- Bus Decoding: The oscilloscope supports various serial bus decoding protocols including RS-232/422/485/UART, CAN, CAN FD, LIN, SPI, and I2C. Configure these settings in the 'Decode' menu.

The MHO14 Series supports self-calibration. Refer to the device's on-screen menu or the detailed datasheet for instructions on how to perform a self-calibration to ensure measurement accuracy.
6. Troubleshooting
- Device does not power on: Ensure the battery is charged or the device is connected to the power adapter. Check the power button for proper function.
- No waveform displayed: Verify that probes are correctly connected to the input channels and the signal source. Check channel enable/disable status. Adjust vertical and horizontal scales, and trigger settings. Use the 'Auto Set' function.
- Inaccurate measurements: Perform a self-calibration. Ensure probes are properly compensated and set to the correct attenuation ratio (e.g., 1X, 10X). Check probe connections.
- Touchscreen unresponsive: Restart the device. Ensure the screen is clean and free from debris.
- Multimeter readings are incorrect: Ensure test leads are connected to the correct multimeter input jacks (COM, VΩ, mA, A) for the desired measurement type. Verify the function selected on the screen matches the physical connection.
