Abstract

In this paper, newly developed 200 N capacity dead weight force standard machine which is established at UME and TSE will be summarized. The 3 different mass stacks are used for calibrating the force-proving instruments together with 3 different loading frames. In the first mass stack, there are two force ranges which are 10 N and 20 N. In the second mass stack, there is only one force range is 50 N and the last one, there are also 2 force ranges are 100 N and 200 N. Each loading frame generates the first force step. This machine is developed as computer controlled system for automatic calibration. Each force range is generated by 10 steps loading and has an additional mass for 110 % overloading test. The main advantage of this machine is that it has newly developed hanging and centering mechanism during both loading and unloading process of the masses. The measurement uncertainty of both systems is 5 × 10^-5 which can be achieved theoretically.
