How do you release spring tension on a click-type wrench?

To release spring tension on a click-type torque wrench, first, turn the adjusting knob or handle counterclockwise until the scale reads zero or the lowest setting. This action decompresses the internal spring mechanism, preventing any residual tension that could lead to inaccurate torque readings. Always ensure to store the wrench in this relaxed position to maintain its calibration and prolong its lifespan.
