3. Setup

3.1 Battery Installation

The torque wrench requires two AA batteries (included). Follow these steps for installation:

1. Locate the battery cover at the end of the handle.
2. Use a coin or a flat-head screwdriver to open the battery cover by rotating it counter-clockwise.
3. Insert two AA batteries, ensuring correct polarity (+/-).
4. Close the battery cover by aligning the small black and red triangles on one line and rotating clockwise until secure.
5. Press the 'C' (ON/OFF) button to power on the wrench.

Figure 3.1: Steps for battery installation: 1. Open the battery cover. 2. Put in AA batteries. 3. Close the battery cover. 4. Press the C button to use.

4. Operating Instructions

4.1 Power On/Off

• To power on, press the 'C' button.
• To power off, press and hold the 'C' button for 3 seconds.

4.2 Measurement Modes

The wrench offers two primary measurement modes: Peak Mode and Track Mode.

• Peak Mode: Displays the maximum torque value achieved during the application. This data is automatically saved.
• Track Mode: Displays real-time torque values as force is applied.

Figure 4.1: The digital display can show real-time torque in Track Mode or record the maximum torque in Peak Mode.

4.3 Unit Switching

The wrench supports four measurement units: kg-cm, Nm, in-lb, and ft-lb.

• Press the 'U' button to cycle through the available units.

Figure 4.2: The wrench supports multiple measurement units for versatility.

4.4 Torque Value Preset and Storage

You can preset up to six torque values (M1 to M6) for frequently repeated applications. The wrench can store up to 600 sets of data.

1. Press the 'M' button to select a preset mode (M1-M6).
2. Use the Up (∧) and Down (∨) arrow buttons to adjust the desired torque value.
3. Each preset mode allows you to choose between Track or Peak Mode.

4.5 Reminder Mode

The wrench provides alerts as you approach the preset torque value:

• At 85% of the target torque, the buzzer will sound and LEDs will illuminate.
• At 90% of the target torque, the buzzer will sound more frequently and more LEDs will illuminate.
• At 100% of the target torque, the buzzer will sound continuously, and all red LEDs will illuminate. This helps prevent over-tightening and screw damage.

Figure 4.4: The digital display provides clear readings, and the integrated buzzer and LED indicators provide alerts for precise torque application.

4.6 Saving Mode (Lock/Unlock & Auto Sleep)

• Lock/Unlock: Press and hold the 'M' key for 3 seconds to lock the buttons and prevent accidental operation. Repeat to unlock.
• Auto Sleep: To conserve battery life, the screen backlight will turn off after approximately 3 minutes of inactivity. The wrench will automatically enter sleep mode after 5 minutes of inactivity.

Figure 4.5: The display indicates 'LoCt' when locked and 'UnLt' when unlocked.

Figure 4.6: Auto Sleep Function: The screen dims after 3 minutes and enters sleep mode after 5 minutes of inactivity.

5. Maintenance

5.1 Cleaning

• Wipe the wrench clean with a soft, dry cloth after each use.
• Do not use abrasive cleaners or solvents, as they may damage the finish or electronic components.

5.2 Storage

• Always store the digital torque wrench in its original protective case to prevent damage.
