ABSTRACT:
In order to be able to carry out accurate measurements with a V.sub.0 -measurement device, it is important that the desired distance between the two measurement coils of the measurement device be accurately maintained. It has been found that it does not suffice to accurately measure the distance between the end faces of the two measurement coils, since the magnetic field foci of individual measurement coils do not always have the same spacing from the end surfaces. The distance between the magnetic field foci of both measuring coils is measured and is employed for determining the muzzle or initial velocity V.sub.0.
