5.3. Setting Torque Value

• Use the ^ (Up) and v (Down) buttons to adjust the target torque value.
• The value will increase or decrease with each press. Hold the button for faster adjustment.

5.4. Track Mode vs. Peak Mode

The screwdriver offers two operational modes:

• Track Mode: Displays the real-time torque value as it is applied. The display resets when the torque is removed.
• Peak Mode: Captures and displays the maximum torque value achieved during the tightening process. This value remains on the screen until cleared.
• To switch between modes, press the U button for 1 second to enter "Mode". Then press U again to enter the Peak/Track change mode. Use ^ or v to toggle, then press U to confirm.
• To clear the peak torque value in Peak Mode, press the C button.

5.5. Preset Modes (M1-M6) and Data Storage

The device allows for storing up to 6 preset torque values and records up to 500 sets of data in Peak mode.

• Setting Presets: The manual states that changing the torque value with the up or down button automatically stores the new value in the currently selected preset register. To access different preset registers (M1-M6), refer to the detailed instructions in the included product manual.
• Data Recall: In "Mode" (press U for 1 second), select "Dat" mode using ^ or v, then press U to enter. Use ^ or v to browse stored data points.
