4. Operating Instructions

4.1 Power On/Off

• Power On: Short-press the 'C' (red) button. The LCD screen will illuminate.
• Power Off: Long-press the 'C' (red) button until the screen turns off.

4.2 Unit Selection

The screwdriver supports five measurement units: in·lb, ft·lb, N·m, kg·cm, and kg·m.

• Press the 'U' button to cycle through the available units. The selected unit will be displayed on the LCD screen.

4.3 Mode Selection (Peak/Tracking)

The screwdriver features two operating modes:

• Peak Mode (P): Displays the maximum torque value applied during an operation.
• Tracking Mode (T): Displays real-time torque values as force is applied.
• Press the 'P/T' button to toggle between Peak and Tracking modes.

4.4 Preset Torque Values (P1-P9)

You can preset up to 9 different torque levels for quick access:

1. Use the '▲' (up) or '▼' (down) buttons to select a preset slot (P1-P9).
2. Press the 'M' button to confirm the selected preset slot. The torque value will start flashing.
3. Use the '▲' or '▼' buttons to adjust the desired torque value.
4. Press 'M' again to save the new preset value.

4.5 Torque Application and Alert System

When applying torque:

• The digital LCD screen displays real-time torque values.
• As the applied torque approaches the target value, the device provides visual and auditory feedback:
• At 80% of target: LED lights flash, and a distinct beeping sound begins.
• At 90% of target: LED lights flash faster, and the beeping sound becomes more rapid.
• At 100% of target: LED lights remain solid, and the beeping sound becomes continuous, indicating the target torque has been reached. This helps prevent over-tightening.

4.6 Memory Management

The device can store up to 500 torque values:

• Store Data: During operation, short-press the 'M' button to instantly store the current torque data.
• Memory Management: Long-press the 'M' button to enter memory management. Use 'U' to select "Delete All" or "Delete Single", then confirm with 'M'.
