Beschreibung
Zusammenfassung:	FIELD: physics. ^ SUBSTANCE: forced oscillation is excited in a product; forced oscillation frequency is changed until resonance oscillation occurs in a product; resonance oscillation parameters are measured. At that oscillation is excited in a product by electromagnetic method; phase difference between reference excitation signal and product oscillation is measured in several various points; and variations of phase oscillation difference shows defectiveness. Faultless products show phase difference variation of certain ratio; and in case of defect it will jump, that will be indicator of product defectiveness. ^ EFFECT: improved accuracy and reliability of product operating conditions control. ^ 2 dwg
