The FAROArm is portable and can be mounted in a variety of environments. The counterbalance by the tension spring generates torque at the base of the FaroArm to allow easy movement of the arm. The arm is not designed to be mounted on sideways on a wall or upside down. This will affect accuracy and cause added stress to the arm. Therefore the arm must me mounted in an upright position.
The only exception to this is some legacy model arms that were specially designed to be mounted upside down. These are referred to as Inverted Arms.
