Abstract
The solid-state oscillator, preferably a watch crystal (1/2), is mounted with its direction (S) of vibration at an angle to all three measuring directions (x, y, z) of the coordinate measuring apparatus. The oscillator circuit of the solid-state oscillator is connected to an electronic circuit which generates two different contact signals. Both measures make it possible to reduce the dependency of the contact uncertainty of the measuring direction.
