With an eccentricity width value of 0.34mm, even if there is no inherent wow and flutter (speed error) produced by the turntable in use, it reaches around 0.15% (WTD RMS) on the innermost grooves of the records playing surface. In reality, the average speed error value of even the highest quality turntables is around 0.008%. These factors combined can result in an overall wow and flutter value 20 times worse than that of the turntable in isolation.
Put simply, when using even the finest quality turntables available, the overall wow and flutter of the entire system cannot be significantly reduced unless the eccentricity of the record is corrected. In order to faithfully reproduce the source material it is imperative to reduce the record eccentricity as much as possible.

Adjustment in 3 Steps
Measurement
When the record player is rotated, the upper part of the stabilizer is held to stop the rotation of the stabilizer, and the stabilizer detects the rotation and shifts to the measurement mode. When switch to the measurement mode, the display on the outer circumference of the stabilizer starts to rotate and the [Tap to start measure] button is displayed. Next, when you press the [Tap to start measure] button, the display changes to the [Measuring] button and the measurement is completed in about 2 seconds.
Adjustment
Stop the record player when the measurement is complete. Next, while looking at the stabilizer screen, press the record board to bring the cross mark (center of rotation) as close as possible to the absolute center position. The degree of eccentricity of the record is indicated by the color of the screen (outer circumference, cross mark & display bar at the bottom).
Restart
When the center of rotation is aligned with the absolute center position, rotate the record player again to check that the eccentricity of the record is gone(or reduced) and then play the record.
Be sure to rotate the record player (33 rotations or 45 rotations) when measuring. If the record player is not spinning, the stabilizer will not be in measurement mode.
