4.11.2. Place the tool on the bolt or nut. Grip the torque wrench handle and pull on the wrench with quick movements. Avoid jerky movements.
4.11.3. With the target torque pre-set, the target value is indicated on the screen.
4.11.4. The LED light will be flashing GREEN when you are in the upper 50%-98% of the programmed torque value.
4.11.5. When you approach the programmed torque value in (+/- 5Nm) the buzzer will sound.
4.11.6. When you are within 2% of the programmed value, the RED light will be seen and you will feel a vibration in the handle. Once +/- 2 Nm of the desired torque value is achieved, the buzzer will emit a quicker sound sequence.
4.11.7 When you are over 2% of the programmed torque, the buzzer will emit a continuous tone, the LED will turn GREEN and a vibration will be felt in the handle.
4.11.8. During the PEAK mode, the maximum value reached will be saved additionally and the value is shown on the display. After releasing the wrench for approx. 2 seconds, this value is flashing, then you can keep going for the next application.
ATTENTION: When you hear the continuous tone, stop pulling immediately in case the target torque is low.
Never use the torque wrench when it has a low battery. The wrench’s accuracy will be affected.
“—-” will be shown on the screen, when applying torque is exceeded at 100% of the maximum torque value.
