Rotating shaft runout and vibration measurements --- Model 211 (high-speed, Ultra high-resolution type)

Measuring Rotating Shaft Runout (RRO, NRRO)
In testing rotating shafts, it is important to measure all aspects of runout under actual operating conditions. RRO (Repeatable RunOut) : Amount (p-p) of runout in 1 rotation NRRO (Non-Repeatable RunOut) : Deviation of runout during more than 10 rotations Measurement Examples

Measuring Vibration
High-speed vibration is measured using a capacitive displacement meter and oscilloscope, FFT, etc.

High-resolution (noise level) and high-linearity measured data --- Model 211

High Resolution	(actual data of noise level measurements)
1 nanometer resolution is achieved by reducing noise level.
