6. Operating Instructions
6.1. Unit Selection
Press the 'U' button to cycle through the available measurement units: N·m, ft-lb, in-lb, kg-cm, kg-m. Select the desired unit for your application.
6.2. Mode Selection (Peak, Track, Preset)
Press the 'M' (Function) button to switch between the three operating modes:
- Track Mode: Displays the real-time torque value as it is applied.
- Peak Mode: Captures and displays the maximum torque value applied during an operation.
- Preset Mode: Allows you to set a target torque value. The wrench will alert you when this value is approached and reached.
6.3. Setting Preset Values
In Preset Mode, use the '▲' (Up) and '▼' (Down) buttons to adjust the target torque value. The wrench supports 10 preset values (P0-P9) for quick access. Press 'C' to confirm the torque setting.
6.4. LED & Buzzer Alert System
When approaching the target torque in Preset Mode, the wrench provides visual and audible alerts:
- Green LED: Activates at 80% of the target torque.
- Red LED: Activates at 90% of the target torque.
- Both LEDs ON & Buzzer: Activates at 100% of the target torque, indicating the desired torque has been reached. This helps prevent overtightening.
6.5. Applying Torque
Once the desired settings are configured, apply steady force to the wrench until the target torque is reached, indicated by the LED and buzzer alerts. Avoid sudden movements.
7. Maintenance
- Cleaning: Wipe the wrench with a clean, dry cloth after each use. Do not use water, alcohol, or corrosive cleaning agents.
- Storage: Store the wrench in its protective case in a dry, cool place, away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display. Remove batteries if the tool will not be used for an extended period.
- Calibration: For continued accuracy, periodic calibration by a certified service center is recommended, especially after significant use or impact.
