5. Setup
5.1 Battery Installation
The device requires batteries for operation. Ensure correct polarity when inserting. If the buzzer does not sound upon power-on, press and hold the P/T and M buttons simultaneously in the shutdown state to reactivate it.
5.2 Attaching Adapters
The 1/2" digital torque adapter can be used directly with 1/2" drive sockets. For 3/8" or 1/4" drive sockets, use the included adapters. Securely attach the adapter to the torque adapter's drive and then attach your desired socket.
Figure 3: The adapter can convert any wrench into a digital torque wrench using the provided 1/2" to 3/8" and 1/2" to 1/4" adapters.
Video 2: Demonstrates unboxing, components, and how to attach the digital torque adapter to a wrench and use the included adapters.
6. Operating Instructions
6.1 Power On/Off
Press the 'C' button to power on the device. To power off, press and hold the 'C' button for a few seconds.
6.2 Setting Torque Values
After powering on, use the Up and Down arrow buttons to adjust the desired target torque value. The device supports 10 groups of preset values (P0-P9) for quick access to frequently used settings.
Figure 4: The adapter features preset value modes and data storage.
Video 3: Demonstrates powering on, reducing and increasing preset torque values, switching between 4 units, and toggling between peak and real-time modes.
6.3 Changing Measurement Units
Press the 'U' button to cycle through the four available measurement units: Nm, in-lb, ft-lb, and kg-cm.
Figure 5: The display shows four measurement modes for versatile use.
6.4 Peak and Track Modes
Press the 'P/T' button to switch between Peak mode and Track mode.
- Peak Mode: Records and displays the maximum torque value achieved during the application.
- Track Mode: Displays the torque value in real-time as it is being applied.
6.5 Buzzer and LED Indicators
As you approach the target torque, the device will emit a regular beep sound. The LED indicator light will change from a flashing green light to a solid red light when the target torque is reached, signaling to stop applying force.
Figure 6: Buzzer and LED alerts provide clear notification when target torque is achieved.
6.6 Data Storage
The adapter can store up to 500 sets of data. Use the 'M' button to save and query stored torque values. You can preset and save 10 groups of torque values from P0 to P9.
