摘要：

We are carrying out a high-precision measurement of the gravitational constant G by means of a beam balance, Test measurements with water as field masses have been made and G has been determined with an uncertainty of 240 x 10(-6) [1]. In the next step 13.5 tons of mercury will be used as field masses. The preparations for these measurements are briefly described in this paper.
