The machine is good
The machine is still acceptable
The machine is not acceptable
 The rotation frequency and the number of measurement points used to compute the diagnosis
 The comment concerning the general status
 The list of detected defects with for each one:
o The type
o The severity:
Slight defect
Defect to be monitored
Defect to be corrected
o The confidence of the diagnosis:

Notes: rotation speed is a very important parameter to get a good result. If the actual rotation speed is not correct,
it is possible to measure it again for variable speed machine or to adjust it using the stroboscope.
This adjustment is also possible with fixed speed machine. In this case the new rotation speed is used to
update the NEST initial setting.
