Speed Synchronisation
Every measurement of complex spectrum (required for balancing) requires the speed synchronisation
by an external pulse.
This must be a once-per-revolution trigger. In the case of order analysis measurements, amplitude
and phase measurements and all measurements in the balancing module the speed synchronisation
is required.
Every measurement in balancing module requires connection of tacho
probe. Balancing process requires stable speed of machine and all steps
should be made at the same speed.
Order Analysis
A standard option of the Adash 4300-VA3 is order analysis. It is a special case of complex spectrum
measurement. The first spectrum line is the speed frequency, next lines are the harmonics.
Description of order analysis measurement – see [1], chapter Dyn. Measur. – Setup Menu / Order
Analysis item
Stable phase is important for the balancing process. Please follow these directions:
- use as high a resolution setting (RESOL parameter) as you can whist checking that the phase is
stable,
- phase values are comparable only with the same set of RESOL and HARM-NMB parameters.
Amplitude and Phase Measurement
Adash 4300-VA3 instrument can measure amplitude and phase of the vibration. The basic is the order
analysis, from which the first line is displayed. Measurement of amplitude and phase – see [1],
chapter Analyser Menu / Ampl. & phase measur. Item.
