5. Setup

5.1 Battery Installation

Locate the battery compartment on the back of the digital torque adapter.
Use the provided screwdriver to open the battery compartment cover.
Insert two AAA batteries, ensuring correct polarity (+/-).
Replace the battery compartment cover and secure it with the screw.

5.2 Attaching to a Wrench

Select a suitable square drive wrench (e.g., ratchet wrench, breaker bar).
Insert the 1/2 inch square drive of the digital torque adapter into the drive end of your wrench. Ensure it is fully seated.
If using a smaller drive size (1/4 inch or 3/8 inch), attach the corresponding adapter to the digital torque adapter first, then attach your socket to the adapter.

6. Operating Instructions

6.1 Power On/Off

Press the 'M' button to power on the device. The LCD screen will illuminate. To power off, press and hold the 'M' button for a few seconds.

6.2 Unit Conversion

With the device powered on, press the 'U' button to cycle through the available measurement units: N.m, Ft.lb, In.lb, Kg.cm. Select the desired unit for your application.

6.3 Mode Selection (TACK / PEAK)

Press and hold the 'U' button for 3 seconds to switch between TACK and PEAK modes. Use the up/down arrow buttons to confirm the selection.

TACK Mode: Displays the torque value in real-time as force is applied.
PEAK Mode: Captures and displays the maximum torque value achieved during the tightening process. The value remains on the screen after force is removed.
