5. Operating Instructions

5.1 Basic Oscilloscope Operation

1. Connecting Probes: Connect the passive probes to the desired analog input channels (CH1-CH4) on the front panel. Ensure a secure connection.
2. Power On: Turn on the oscilloscope. The 8-inch HD touchscreen will display the main interface.
3. Input Signal: Apply the signal you wish to measure to the connected probe.
4. Auto Setup: For quick initial setup, press the 'Auto Set' button. The oscilloscope will automatically adjust vertical, horizontal, and trigger settings to display a stable waveform.
5. Manual Adjustments: Use the dedicated knobs and touchscreen controls for fine-tuning.
   • Vertical Controls: Adjust voltage scale (V/div) and position for each channel.
   • Horizontal Controls: Adjust time base (s/div) and horizontal position.
   • Trigger Controls: Set trigger level, mode (Edge, Pulse Width, Video, etc.), and source to stabilize the waveform.
6. Measurements: Access the measurement menu to perform automatic measurements (e.g., Vpp, Vrms, Frequency, Period) or use cursors for manual measurements.

5.2 Multimeter Functionality

The MHO14-100 integrates a 4½-digit multimeter. To use the multimeter:

1. Switching Modes: Select the multimeter function from the main menu or a dedicated button (if available).
2. Connecting Multimeter Pens: Connect the multimeter pens to the dedicated input jacks (COM, VΩmA, 10A) on the front panel, corresponding to the measurement type.
3. Select Measurement Type: Choose the desired measurement (Voltage, Current, Resistance, Capacitance, Diode, Continuity) on the screen.
4. Perform Measurement: Apply the multimeter pens to the circuit or component under test. The measurement will be displayed on the screen.

5.3 Advanced Features

• Remote Control: The oscilloscope supports remote control via SCPI commands, mobile applications (Android/iOS), and PC software. Connect the device to a network via the LAN port or USB for remote access.
• HDMI Output: Use the HDMI port to connect the oscilloscope to an external display for larger viewing and analysis.
• Data Storage: The device offers 110Mpts memory depth and segmented storage, allowing you to capture and analyze complex waveforms and multiple trigger events efficiently. Save waveforms, screenshots, and setup configurations to internal memory or a connected USB drive.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. For stubborn dirt, a slightly damp cloth with mild detergent can be used. Avoid abrasive cleaners or solvents.
• Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Store the device in a cool, dry place if not used for extended periods, and charge it periodically.
• Software Updates: Check the manufacturer's website for available firmware updates to ensure optimal performance and access to new features.
• Probe Calibration: Periodically check and calibrate your oscilloscope probes according to standard procedures to maintain measurement accuracy.

7. Troubleshooting

• Device Not Powering On: Ensure the battery is charged or the power adapter is securely connected and receiving power.
• No Waveform Display: Check probe connections, input signal presence, and trigger settings. Try using the 'Auto Set' function.
• Unstable Waveform: Adjust the trigger level and trigger mode. Ensure the trigger source is correctly selected.
• Inaccurate Measurements: Verify probe compensation and calibration. Ensure correct measurement settings are selected for the multimeter.
• Touchscreen Unresponsive: Restart the device. If the issue persists, contact support.
