Different operators will apply different forces to manual torque measuring devices, and the force applied directly relates to the torque measured. When torque is measured by using a manual torque meter, an operator’s hand is responsible for applying the twisting force to the cap in order for the cap to rotate to the removal point or application point.
At this point, torque data is recorded and displayed on the torque measurement device. During this process, an increase in the force applied by the operator to the cap, or an increase in the speed at which the force is applied, will result in an increase in the measured torque of the cap, and vice-versa. In order for accurate and reliable data to be obtained, each operator must apply precisely the same amount of force to the cap, testing cycle after testing cycle. With a motorized torque testing system, the force applied to a cap is precisely the same in each testing cycle, regardless of who may be operating the machine, or how strong they may be.
