    Abstract: The method of making a force-responsive instrument of the type including a tensioned wire of round cross-section to be vibrated perpendicular to the wire axis, wherein said instrument includes field-producing magnetic means operable with said wire to induce vibration; said method including the steps of:positioning said wire in a magnetic field directed perpendicularly to the wire axis;vibrating said wire by electrical means connected to the wire and arranged to develop interaction with said magnetic field;developing an electrical signal proportionately responsive to the magnitude of vibrations of said wire;effecting relative rotation between said wire axis and said magnetic field while maintaining constant the intensity of said magnetic field;making measurements of the amplitude of the signal developed by said wire;determining from said measurements the position of said wire relative to said magnetic field providing maximum signal amplitude; andfixing said wire in said instrument in said position relative to said magnetic means.
