Setting Torque Value (Presets):

• The wrench allows you to save up to 9 preset torque values (P1-P9).
• To select a preset, use the Up/Down arrow keys.
• To adjust a preset value, select the desired preset (e.g., P1), then use the Up/Down arrow keys to change the value. Long-press for quick adjustment, short-press for precise adjustment.
• Press the 'M' button to save the adjusted preset value.

Operating Modes

Peak Mode (P):

• In Peak mode, the wrench displays the maximum torque value applied during the tightening process.
• Once the set target torque is reached, the wrench will provide alerts.

Track Mode (T):

• In Track mode, the wrench displays the real-time torque value as it is being applied. This is useful for continuous monitoring during tightening.

Torque Memory (M):

• The wrench can store up to 500 torque values in its memory.
• To save a torque value, apply torque, then briefly press the 'M' button.
• To recall stored values, long-press the 'M' button, then use the Up/Down arrow keys to navigate through the stored data.
• To delete stored values, long-press the 'U' button, then select 'ALL' or 'onE' using the Up/Down keys, and press 'M' to confirm deletion.

Dual-Direction Ratchet:

• The wrench features a reversible ratchet head, allowing for both clockwise (tightening) and counterclockwise (loosening) operations.
• Use the lever on the ratchet head to switch directions.

Alerts:

• The wrench provides multiple alerts to indicate when the target torque is approached or reached:
• LED Indicators: Lights illuminate in sequence as the target torque is approached, turning red when reached.
• Buzzer: A continuous beep sounds when the target torque is reached.
• Vibration: The handle vibrates to provide tactile feedback when the target torque is reached.

Practical Application

This digital torque wrench is ideal for ensuring precise tightening of fasteners on vehicles, bicycles, and other machinery. The multiple alert systems provide confidence in achieving the correct torque without over-tightening.
