Abstract :
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 240×10-6. 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
