1. Product Overview
The Shahe Digital Torque Wrench Adapter is a precision instrument designed for monitoring torque during fastening and loosening operations. It converts any standard ratchet or breaker bar into a digital torque wrench, making it suitable for automotive, bicycle, and general machinery maintenance, as well as other industrial applications.
This device offers high accuracy and multiple operating modes to enhance work efficiency.
Key Features:
- Bidirectional reading error: ±2% clockwise and ±2.5% counter-clockwise.
- Four selectable torque units: kgf.cm, Nm, lbf.ft, lbf.in.
- Audible and visual alarm function with backlight for low-light conditions.
- Three operating modes: Real-time, Peak, and Preset.
- Automatic shut-off after 10 minutes of inactivity to conserve battery life.
- Powered by 2 x 1.5V AAA batteries.

3. Operating Instructions
Controls and Display:
- Display Screen: Shows torque readings, units, and mode.
- '+' Button: Increases values or navigates menus.
- '-' Button: Decreases values or navigates menus.
- 'M' (Mode) Button: Switches between Real-time, Peak, and Preset modes.
- 'U/S' (Unit/Save) Button: Changes torque units and saves settings.
- 'P/C' (Power/Clear) Button: Powers the unit on/off and clears readings.
- Indicator Light: Illuminates to indicate target torque reached.
- Buzzer (rear): Emits an audible alarm when target torque is reached.
Power On/Off:
Press the 'P/C' button to power the unit on. To power off, press and hold the 'P/C' button for a few seconds.
Selecting Torque Units:
Press the 'U/S' button repeatedly to cycle through the available torque units: kgf.cm, Nm, lbf.ft, lbf.in.
Operating Modes:
Press the 'M' button to switch between the following modes:
- Real-time Mode (Track): Displays the current torque being applied.
- Peak Mode (Peak Hold): Captures and displays the maximum torque applied during an operation.
- Preset Mode (Target): Allows you to set a target torque value. The unit will alarm when this value is reached.
Setting Target Torque (Preset Mode):
- Switch to Preset Mode using the 'M' button.
- Use the '+' and '-' buttons to adjust the target torque value.
- Press the 'U/S' button to confirm and save the preset value.
Audible and Visual Alarms:
When operating in Preset Mode, the unit will provide an audible beep and the indicator light will illuminate when the applied torque reaches the preset target value. This helps prevent over-tightening.
Note: The backlight and buzzer function activate only when the target or nominal value is reached.
4. Maintenance
- Cleaning: Wipe the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the digital torque adapter in its protective case in a dry, cool place when not in use. Remove batteries if storing for extended periods to prevent leakage.
