3. Setup

1. Unpacking: Carefully remove the oscilloscope and all accessories from the packaging. Verify all components listed in the packing list are present.
2. Power Connection: Connect the provided power adapter to the oscilloscope's power input and then to a suitable AC power outlet.
3. Initial Power On: Press the power button located on the device. The system will boot up and display the main interface.
4. Probe Connection: Connect your desired probes (e.g., passive probes, active probes, current probes) to the appropriate input channels (CH1-CH4) on the front panel. Ensure a secure connection. The Mic-OPI™ interface automatically detects and configures compatible probes.
5. External Connections: If needed, connect external devices using the USB 3.0 Host, USB Type-C, LAN, or HDMI ports located on the side/rear panel.

4. Operating Instructions

The MHO 3 Series oscilloscope offers both touch screen and physical button controls for flexible operation.

4.1 Basic Waveform Acquisition

• Channel Selection: Tap on the desired channel (CH1-CH4) on the screen or use the dedicated channel buttons to enable/disable channels.
• Vertical Scale (Volts/Div): Adjust the vertical scale using the touch interface or the dedicated vertical scale knob for each channel.
• Horizontal Scale (Time/Div): Adjust the horizontal time base using the horizontal scale knob or by pinching/zooming on the touch screen.
• Trigger Setup: Configure the trigger settings (Edge, Pulse, Video, etc.) to stabilize the waveform. Use the dedicated trigger controls or the touch menu.
• Run/Stop: Press the RUN/STOP button to start or stop waveform acquisition.

4.2 Advanced Features

• Measurements: Access automatic measurements (e.g., Vpp, Vrms, Frequency) through the measurement menu.
• Math Functions: Perform waveform math operations (e.g., Add, Subtract, Multiply, Divide, FFT) using the Math menu.
• Storage: Save waveforms, setups, or screenshots to internal memory or a connected USB drive. The segmented storage function allows capturing up to 10,000 segments.
• Remote Control: Utilize the mobile app or PC remote control software for remote operation via LAN or Wi-Fi (if applicable).

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the oscilloscope. For the screen, use a screen-specific cleaning solution and a microfiber cloth. Avoid abrasive cleaners or solvents.
• Storage: When not in use, store the oscilloscope in a clean, dry environment, away from direct sunlight, extreme temperatures, and excessive dust.
• Calibration: Regular calibration by qualified personnel is recommended to maintain measurement accuracy. Refer to the manufacturer's guidelines for recommended calibration intervals.
• Software Updates: Periodically check the Micsig official website for firmware updates to ensure optimal performance and access to new features.
