FRF Frequency Response Function Extension Module
The status indicators provide feedback on the hammer hits.
See the Dynamix 2500 Data Collector User Manual, publication
1441-UM001
,
for more information about the status indicators:
•
If the Accept/Reject option in FRF - Setup was set to Automatic, each
hammer hit is collected and the Dynamix 2500 data collector
automatically determines if the data is correct. If it is not, a message appears
with details on why the hit was rejected.
•
If Accept/Reject was set to Manual, the hammer and response time
waveforms display for both the hammer and accelerometer outputs, and
then an Accept/Reject prompt appears.
4.
Review the FRF data and either Accept or Reject the hit.
When all the averages are taken, the Taking Data screen updates to show
the FRF magnitude/phase traces.
