When the wrench clicks, the designated amount of torque has been applied. Stop pulling. Continuing to pull after the wrench clicks can increase the applied torque to a value that exceeds the engineering specification. 

This micrometer adjustable torque wrench measures and applies torque in the clockwise direction. Using this wrench in the counter-clockwise direction will apply torque, but it will not measure torque because it does not click in the counter-clockwise direction.
