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) |
