4. Setup
4.1 Battery Installation
The torque wrench requires two AA batteries (included). Follow these steps to install them:
- Locate the battery cover at the base of the handle.
- Rotate the battery cover counter-clockwise to open it.
- Insert two AA batteries, ensuring correct polarity (+/-).
- Replace the battery cover and rotate it clockwise to secure.
- Press the 'C' button to power on the device.

5. Operating Instructions
5.1 Power On/Off
- To power on: Press the C button.
- To power off: Press and hold the C button for a few seconds until the display turns off. The wrench will also automatically power off after a period of inactivity.
5.2 Selecting Measurement Units
The wrench supports five units of measure: ft-lbs, in-lbs, Nm, kg-cm, and kg-m.
- Press the U button to cycle through the available units. The selected unit will be displayed on the screen.

5.3 Setting Torque Values (Preset Mode)
The wrench allows for setting up to 9 groups of preset torque values.
- Press the M button to enter preset mode (indicated by 'P' on the display, e.g., P1, P2).
- Use the Up and Down arrow buttons to select the desired preset group (P1-P9).
- Press the C button to confirm the selected preset group.
- Use the Up and Down arrow buttons to adjust the target torque value for that preset.
- Press the C button again to save the value and exit setting mode.
5.4 Operating Modes: Peak and Track
The wrench offers two operating modes:
- Track Mode: Displays the torque value in real-time as it is being applied.
- Peak Mode: Captures and displays the maximum torque value achieved during the application.
To switch between modes, press the M button until the desired mode (Track or Peak) is indicated on the display.

5.5 Applying Torque
Once your desired torque value and unit are set:
- Attach the appropriate socket or accessory to the quick-release head.
- Place the wrench onto the fastener.
- Apply steady, smooth force. The display will show the real-time torque (in Track mode) or the peak torque (in Peak mode).
- As you approach the preset torque value, the wrench will provide visual and audible alerts:
- Green LED: Illuminates when 85%-90% of the target torque is reached.
- Red LED & Buzzer: Activates when 100% of the target torque is reached.
- Stop applying force immediately when the red LED illuminates and the buzzer sounds to avoid over-torquing.

5.6 Data Storage and Recall
The wrench can store up to 500 groups of data. To check historical data:
- In operating mode, press and hold the M button to enter data query mode.
- Use the Up and Down arrow buttons to scroll through stored data records.
- Press the C button to exit data query mode.
- To clear all stored data, press and hold the C button while in data query mode until "CLR" appears on the display.
6. Maintenance
- Cleaning: Wipe the wrench with a clean, dry cloth after each use. Do not use abrasive cleaners or solvents.
- Storage: Store the wrench in its original protective case in a dry, cool place, away from direct sunlight and extreme temperatures.
- Battery Care: Remove batteries if the wrench will not be used for an extended period to prevent corrosion. Replace batteries when the low battery indicator appears on the display.
- Calibration: For optimal accuracy, it is recommended to have the torque wrench calibrated periodically, especially after 12 months or 5000 uses.
