5. Setup
5.1 Battery Installation
- Locate the battery compartment cover at the base of the handle.
- Twist or slide the cover to open it.
- Insert the included AAA batteries, ensuring correct polarity (+/-).
- Replace the battery compartment cover securely.
5.2 Initial Power-On
Press the 'C' (Power) button to turn on the wrench. The LCD screen will illuminate, and the wrench will perform a self-test before displaying the current settings.
6. Operating Instructions
6.1 Power On/Off
- Power On: Press the 'C' button.
- Power Off: Press and hold the 'C' button for a few seconds, or the wrench will automatically shut down after 3 minutes of inactivity to conserve battery life.
6.2 Unit Selection
Press the 'U' (Unit) button to cycle through the available measurement units: N·m, ft-lb, in-lb, kg-cm, kg-m. Select the unit required for your application.
6.3 Mode Selection
Press the 'M' (Mode) button to switch between operating modes:
- Track Mode: Displays the real-time torque being applied.
- Peak Mode: Records and displays the maximum torque value achieved during an application.
- Preset Mode: Allows you to set a target torque value, with alerts indicating when it is reached.
6.4 Setting Target Torque (Preset Mode)
- Enter Preset Mode by pressing the 'M' button until 'PRESET' or 'P' is indicated on the display.
- Use the 'Up' and 'Down' arrow buttons to adjust the target torque value.
- Confirm the setting by pressing the 'M' button again or waiting a few seconds for it to auto-confirm.
6.5 Using Preset Values
The wrench can store up to 10 preset torque values (P0-P9) for quick access.
- In Preset Mode, press the 'M' button to cycle through the stored preset values (P0-P9).
- To save a new preset, set the desired torque value as described in 6.4, then press and hold the 'M' button until the display flashes, indicating it's saved to the current preset slot.
6.6 Interpreting Alerts
When approaching the target torque in Preset Mode, the wrench provides visual and audible alerts:
- Green LED (80%): Illuminates when 80% of the target torque is reached.
- Red LED (90%): Illuminates when 90% of the target torque is reached.
- Both LEDs ON (100%): Both Green and Red LEDs illuminate, and the buzzer sounds continuously when 100% of the target torque is reached. This indicates the target torque has been achieved, and further tightening should cease to prevent overtightening.
6.7 Data Storage and Recall
The wrench automatically stores up to 500 torque application records. To view or delete stored data, refer to the detailed instructions in the full user manual (if available) or contact customer support.
6.8 Using Extension Bars and Adapter
The included 5-inch and 6-inch extension bars, along with the 3/8"F x 1/2"M adapter, provide increased reach and versatility for accessing fasteners in tight or recessed areas.
7. Maintenance and Care
7.1 Cleaning
After each use, wipe the wrench clean with a dry, soft cloth. Do not use abrasive cleaners, solvents, or alcohol, as these can damage the finish or electronic components. Ensure no moisture enters the display or button areas.
7.2 Storage
Store the digital torque wrench in its protective case when not in use. Keep it in a dry environment, away from direct sunlight, extreme temperatures, and corrosive substances. Remove batteries if the wrench will not be used for an extended period to prevent leakage.
7.3 Calibration
Your YIYEIE Digital Torque Wrench is factory calibrated and includes an ASME & DIN-ISO traceable certificate. While the digital core is designed to maintain accuracy for 35,000 cycles, periodic re-calibration is recommended, especially after heavy use or if accuracy is suspected to be compromised. Contact YIYEIE customer support for re-calibration services.
