5 - 6 Vibrometer function
Synchronous measurement:
1. channel that the measurement displayed refers to
2. status of the channel displayed:
= enabled
= disabled
3. sensor connected to the channel
4. order of the harmonic measured
1xRPM = fundamental harmonic (synchronous with the rotation velocity)
2xRPM = second harmonic (frequency double the rotation velocity)
3xRPM = third harmonic (frequency triple the rotation velocity)
4xRPM = fourth harmonic (frequency four times the rotation velocity)
5xRPM = fifth harmonic (frequency five times the rotation velocity)
5. filter width
6. vibration modulus, with unit and type
7. vibration phase expressed in degrees (0°÷359°)
8. frequency of the harmonic measured; it coincides with the rotation velocity in the
event of a 1xRPM measurement, otherwise it is respectively double, triple, etc.
The measurement can be started and stopped by pressing
