4. Setup

4.1. Charging the Battery

The TAGVIT Digital Torque Wrench is equipped with a rechargeable battery. Before first use, ensure the battery is fully charged.

Figure 4.1: Illustration of the quick-change socket, direction switch, and the three-step process for accessing and charging the rechargeable battery.

1. Locate the battery compartment cover, typically at the base of the handle.
2. Open the cover to reveal the battery and USB charging port.
3. Connect the wrench to a standard USB power source using the provided USB cable.
4. The charging indicator on the screen will show charging status. A full charge typically takes approximately 2 hours and provides up to 12 hours of working time.

4.2. Initial Power On

Press and hold the Power/Reset button (leftmost button) briefly to power on the device. The digital display will illuminate.

5. Operation

5.1. Main Menu Navigation

Long press the U button to access the Main Menu. Use the Up/Down arrow buttons to navigate and the Power/Reset button to select.

Figure 5.1: Main Menu display, showing options such as Set Working Mode, Set Alarm Mode, Set Unit, Set Alarm Value, Set Time, Stored Data Menu, and Set Language.

• Set Working Mode: Choose between Peak Mode (P) and Track Mode (T).
• Set Alarm Mode: Configure T1 (single target value) or T2 (interval values).
• Set Unit: Select desired torque unit (N.m, Ft-lb, in-Lb, Kg.cm).
• Set Alarm Value: Define the target torque for T1 or the range for T2.
• Set Time: Adjust the internal clock.
• Stored Data Menu: Access recorded torque data.
• Set Language: Choose the display language.

5.2. Working Modes: Peak and Track

The wrench offers two primary working modes:

Figure 5.2: Comparison of Peak Mode (P), which captures the maximum applied torque, and Track Mode (T), which monitors real-time torque.

• Peak Mode (P): Captures and displays the maximum torque value applied during an operation. Useful for verifying the highest torque achieved.
• Track Mode (T): Monitors and displays the torque in real-time as it is being applied. Ideal for continuous monitoring during tightening.

To switch between modes, short press the M button or select via the Main Menu.

5.3. Setting Torque Units

From the Main Menu, navigate to "Set Unit" to select your preferred torque unit. Available units include Newton-meters (N.m), Foot-pounds (Ft-lb), Inch-pounds (in-Lb), and Kilogram-centimeters (Kg.cm).

5.4. Applying Torque and Alarm System

Once the desired mode and target torque value are set, attach the appropriate socket to the quick-change ratchet head. Position the wrench on the fastener and apply force smoothly.

Figure 5.3: Visual representation of the LED indicator and buzzer alarm system, showing green light for approaching torque and red light for target torque reached.

• As you approach the target torque (typically 85-90% of the set value), the LED indicator will flash green, and the buzzer will emit intermittent beeps.
• When the target torque (100%) is reached, the LED indicator will turn red, and the buzzer will emit a persistent beep. Stop applying force immediately.

5.5. Data Storage and Recall

The wrench can store up to 512 data values, allowing for detailed record-keeping and review of applied torque. This feature is useful for quality control and documentation.

To access stored data, navigate to the "Stored Data Menu" from the Main Menu. You can review individual records, which typically include the applied torque value, accuracy, and a pass/fail (NG) indication.

6. Maintenance

6.1. Cleaning and Storage

• Wipe the wrench clean with a soft, dry cloth after each use. Do not use abrasive cleaners or solvents.
• Store the wrench in its protective case in a dry, temperature-controlled environment.
• Avoid dropping or subjecting the wrench to harsh impacts.

6.2. Calibration

The TAGVIT Digital Torque Wrench is factory calibrated to meet high accuracy standards (e.g., ISO 6789-1:2017 and ASME B107.14M). Regular calibration is crucial to maintain accuracy, especially after extensive use or if accuracy is suspected to be compromised.

Figure 6.1: The wrench displayed alongside a calibration certificate, highlighting its adherence to ISO 6789-1:2017 and ASME B107.14M standards, and indicating a fatigue test rating of 50,000+ uses.

• It is recommended to have the wrench professionally calibrated annually or after approximately 15,000 uses, whichever comes first.
• Do not attempt to recalibrate the wrench yourself unless you have specialized equipment and training.
