5.2 Initial Power On
Press and hold the power button located on the side or top of the device until the screen illuminates. The device will boot up and display the main interface.
5.3 Attaching Probes and Test Leads
- Oscilloscope Probes: Connect the BNC connector of the oscilloscope probe to the input channels (CH1, CH2) on the device. Ensure a secure connection.
- Multimeter Test Leads: For multimeter functions, connect the red test lead to the VΩmA input and the black test lead to the COM input.
6. Operating Instructions
6.1 Navigating the User Interface
The TO1112C features a multi-touch capacitive screen. Navigate through menus and settings by tapping, swiping, and pinching gestures, similar to a tablet device. The main screen typically displays waveform data, while side menus provide access to different functions like Oscilloscope (OSC), Digital Multimeter (DMM), and settings.

6.2 Oscilloscope Function (OSC)
To use the oscilloscope, select the "OSC" mode from the main menu. You can adjust vertical scale (Volts/Div), horizontal time base (Sec/Div), trigger settings, and measurement parameters directly on the touch screen. The 8M storage depth allows for capturing longer waveforms.
- Auto-Set: Tap the "Auto" button for automatic waveform scaling and triggering.
- Measurements: Access various automatic measurements (e.g., Vpp, Vrms, Frequency) through the "Measure" menu.
- Cursors: Use horizontal and vertical cursors for precise manual measurements.
6.3 Digital Multimeter Function (DMM)
Switch to "DMM" mode to access the multimeter functions. The TO1112C supports measurements for AC/DC voltage, current, resistance, capacitance, diode, and continuity (on-off measurement).
- Data Recording: The multimeter function includes data recording capabilities, allowing you to log measurements over time.
- Trend Chart: View recorded data as a trend chart for analysis.
- Statistical Analysis: Perform basic statistical analysis on recorded data.

7. Maintenance
7.1 Cleaning
Wipe the device with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth with mild detergent. Do not use abrasive cleaners or solvents.
7.2 Battery Care
The device uses two 18650 Lithium Ion batteries. To prolong battery life:
- Avoid fully discharging the battery frequently.
- Store the device in a cool, dry place if not used for extended periods, with the battery charged to about 50%.
- If the battery drains quickly, it may indicate a need for replacement.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery; Power button not pressed correctly. | Charge the device for at least 30 minutes. Press and hold the power button firmly for a few seconds. |
| Screen is unresponsive. | Software glitch; Screen protector interference. | Restart the device. Ensure the screen is clean and free of debris. Remove any non-standard screen protectors. |
| Inaccurate measurements. | Improper probe compensation; Incorrect settings; Faulty probes/leads. | Perform probe compensation. Verify measurement settings (e.g., AC/DC coupling, attenuation). Test with known good probes/leads. |
| Battery drains quickly. | Aging battery; High brightness settings; Background processes. | Reduce screen brightness. Close unused applications. Consider battery replacement if issues persist. |
