In this work, we simulate the gravitational wave signals from twenty X-MRI systems by an axisymmetric Konoplya\u2013Rezzolla\u2013Zhidenko metric with varied parameters. We find that the mass, spin, and deviation parameters of the Kerr black hole can be determined accurately (\u223c10\u22125\u221210\u22126) with only one X-MRI event with a high signal-to-noise ratio.
