Resonance phenomena are widespread in the field of physics,many colleges and universities offer Pohl resonator instrument experiment in order to help students to understand the concept of resonance. This pa-per discusses the uncertainty of measurement results for free oscillation,damping vibration and forced vibration of balance wheel,and analyzes the possible factors which affect the measurement results. It is important and significant for understanding the resonance phenomenon and uncertainty analysis.
