2. Setup
2.1 Unpacking and Inspection
Carefully remove the oscilloscope and all accessories from the packaging. Inspect the device for any signs of damage during transit. If any damage is found, contact your supplier immediately.
2.2 Powering On/Off
- To power on, press and hold the power button located on the side of the device until the Micsig logo appears on the screen.
- To power off, press and hold the power button until the shutdown options appear, then select "Power Off".
- The built-in 7500mAh Li-ion battery provides approximately 5 hours of operation. Charge the device using the provided power adapter when the battery level is low.
2.3 Probe Connection
Connect the oscilloscope probes to the input channels (CH1, CH2, etc.) on the device. Ensure a secure connection. Calibrate probes as necessary before making measurements.
3. Operating Instructions
3.1 User Interface
The STO Series oscilloscope features an 8-inch TFT-LCD capacitive touch screen. Navigate menus and control settings by tapping, swiping, and pinching gestures. The integrated control panel with multifunction navigation buttons provides quick and accurate control for common operations.
3.2 Basic Measurements
Connect the probe to the circuit under test. Adjust the vertical scale (Volts/Div) and horizontal scale (Time/Div) using the touch screen controls or navigation buttons to display the waveform appropriately. Use the trigger settings to stabilize the waveform.
3.3 Advanced Features
- Memory Depth: The device features a 70Mpts memory depth, allowing for detailed capture and analysis of long waveforms. Utilize hardware-based Zoom technology for closer inspection.
- Serial Bus Decoding: Supports UART, LIN, CAN, I²C, and SPI serial bus decodings. This feature allows simultaneous display of waveforms and decoded data, simplifying debugging of serial communications.
- Trigger Functions: A wide range of trigger types are available, including Edge, Pulse, Logic, N Edge, Runt, Slope, Timeout, Video, and Serial triggers. Access these via the trigger menu for precise waveform capture.
- Automatic Measurements: The oscilloscope offers 31 types of automatic measurements. These can be displayed on one screen for quick analysis. A single touch can clear all measurements.
- Color Temperature Display: This mode represents the frequency of waveform occurrence using different colors. Red indicates more frequently occurring events, aiding in identifying signal anomalies.
- Bandwidth Filter: High Pass / Low Pass filter functions are available to eliminate insignificant frequencies, reducing interference and allowing observation of the true signal state.
- Remote Control: The device supports remote control via PC software and mobile phone apps (Android / iOS) through Wi-Fi or USB connections.
3.4 Data Storage
The STO Series includes a large 32GB internal storage. This allows users to save waveforms, screenshots, and recorded videos directly on the device. Files can be managed through the Android operating system interface.
4. Maintenance
4.1 Cleaning
To clean the device, use a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected from all power sources before cleaning.
4.2 Battery Care
The built-in Lithium Polymer battery should be charged regularly. Avoid fully discharging the battery frequently to prolong its lifespan. If storing the device for an extended period, ensure the battery is charged to approximately 50%.
4.3 Software Updates
Periodically check the Micsig website or the device's settings for available software updates to ensure optimal performance and access to new features.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or power adapter issue. | Connect the device to the power adapter and allow it to charge for at least 30 minutes before attempting to power on again. Ensure the power adapter is functioning correctly. |
| No waveform displayed. | Probe not connected, incorrect settings, or no signal input. | Verify probe connections. Check vertical and horizontal scale settings. Ensure a signal is present at the probe tip. Adjust trigger level. |
| Unstable waveform. | Incorrect trigger settings. | Adjust the trigger level and trigger type (e.g., Edge, Pulse) to match the input signal characteristics. Ensure the trigger source is correctly selected. |
| Touch screen unresponsive. | Temporary software glitch. | Restart the device. If the problem persists, contact customer support. |
