Features: 

· High Accuracy: Provides precise torque measurements with excellent stability.

· Wide Application: Suitable for torque testing and inspection of fasteners requiring high accuracy.

· Precision Level: Grade 3 accuracy with an error margin of ±3%.

Note: 

○ Zero adjustment before use: Turn the knob in the center of the dial counterclockwise so that the follower needle is close to the driving needle. Rotate the dial so that the follower needle aligns with the zero mark on the scale.

○ Install a suitable socket on the square drive.

○ During use, apply force slowly via the handle until the follower needle reaches the desired torque value.

○ After releasing the force, the driving needle returns to zero, while the follower needle remains in position, allowing you to accurately read the torque just applied.
