Measurement mode

5 kinds of algorithms in 2 measurement modes can be selected depending on measurement requirement. C, D and E modes follow up changes in accelerated/decelerated rotation speed. Even when the maximum peak frequency is lost, the peak value is predicted and the rotation speed can be calculated in the C mode. The D mode can follow up changes of the maximum peak and appropriate rotation speed can be selected from up to 8 frequency peaks in the E mode.

Measurement mode	MODE	Measurement algorithm
Steady rotation measurement (Constant)(This mode is effective when rotating speed of a measurement object is constant.)	A	Maximum power spectrum peak detection method
	B	Peak-interval mode method
Acceleration/deceleration rotation measurement (Active) (This mode is effective when rotating speed of a measurement object changes.)	C	Maximum power spectrum peak detection method (Multi-order peak follow-up method)
	D	Maximum power spectrum peak detection method (Maximum power spectrum peak follow-up method)
	E	Maximum power spectrum peak detection method (Specific power spectrum peak follow-up method)
