5. Setup
5.1 Battery Installation
The Uharbour Digital Torque Wrench requires three (3) AAA batteries for operation. To install or replace batteries:
- Locate the battery compartment cover, typically at the base of the handle.
- Open the cover by twisting or sliding it according to the markings.
- Insert three AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
The wrench is now ready for initial power-on.
6. Operating Instructions
6.1 Power On/Off
- Power On: Press and hold the power button (usually marked 'C' or power symbol) for a few seconds until the display illuminates.
- Power Off: Press and hold the power button until the display turns off. The wrench will automatically power off after a period of inactivity to conserve battery life.
6.2 Unit Selection
The wrench supports multiple measurement units. To change units:
- Press the 'U' button (Unit button) to cycle through available units: N-m, kgf-cm, lb-ft, and lb-in.
- Select the desired unit for your application.
6.3 Mode Selection (Peak & Track)
The wrench offers two primary operating modes:
- Track Mode: Displays the real-time torque value as it is applied. This is useful for monitoring torque during continuous application.
- Peak Mode: Captures and displays the maximum torque value applied during an operation. In this mode, you can set a target torque value, and the wrench will provide alerts (vibration, buzzer, LED) when the target is approached and reached.
Press the 'P/T' button to switch between Track and Peak modes.

6.4 Setting Target Torque (Peak Mode)
To set a target torque value in Peak mode:
- Ensure the wrench is in Peak mode (indicated on the display).
- Press the 'M' button (Memory/Set button) to enter the setting interface.
- Use the Up (▲) and Down (▼) arrow buttons to adjust the target torque value.
- Press the 'M' button again to confirm and save the setting.
6.5 Applying Torque
Once the target torque is set (or in Track mode):
- Attach the appropriate 1/2" drive socket to the wrench head.
- Place the socket onto the fastener.
- Apply steady, smooth force to the wrench handle.
- In Peak mode, observe the LED indicators, listen for the buzzer, and feel for vibration as you approach and reach the target torque. Stop applying force immediately upon receiving the final alert.
- In Track mode, monitor the real-time display to achieve the desired torque.

6.6 Torque Memory
The wrench can store torque value histories for future reference. Consult the specific instructions in the included printed manual for details on accessing and managing stored memory slots (P1-P9).
7. Maintenance
7.1 Cleaning
- Wipe the wrench clean with a soft, dry cloth after each use.
- Do not use abrasive cleaners or solvents, as these can damage the finish or electronic components.
7.2 Storage
