Dead weight with closed-loop control system
Force application by means of dead weight with closed-loop control system combines these two techniques. In this case, part of the test force is applied using directly acting masses and the remainder of the test force with the help of a closed-loop control system. Dead weights are used above all in the case of very low test forces, in order to adhere reliably to the extremely low tolerance limits.
