Deflection and controlling torque, like damping torque, are not explicitly measured, but can be created and thus controlled in different 2ways. By creating these two torques the pointer will move in a specific way that can be analyzed as shown below. Deflection torque can be any type of force that initially puts the system in motion. Controlling torque on the other hand is generated by a measuring device, and thus is not a naturally occurring motion. There are two ways of producing a controlling torque, spring control and gravity control:
