7. Operating Instructions
The MC8 features intuitive controls for easy operation.
7.1. Navigation and Controls
The MC8 utilizes a metal roller and a slider for navigation and input:
- Metal Roller: Rotate to scroll through menus and adjust values. Press to select an option or confirm an action.
- Slider: Used for fine-tuning output values in certain modes (e.g., servo testing).

Figure 5: The metal roller and slider provide precise control.
7.2. Battery Cell Checker
To check battery voltage and balance cells:
- Connect the battery's balance lead to the MC8's balance port.
- The screen will automatically display individual cell voltages and total pack voltage.
- The MC8 can also balance cells if the voltage difference is significant, indicated on the display.

Figure 6: The display shows detailed cell voltage information.
