Collect FRF Data

Once the measurement is set up and the transducers are attached correctly, the

next step is to start collecting data for the FRF.

Follow these instructions to collect FRF Data.

1. From the Setup screen, press Start.

If you have Hammer Range, Response Range, or Num of Lines set to

automatic, a message appears advising you that you will be asked to

perform three trial hits. The results of these hits are used to automatically

determine the best settings for the associated options.

2. Press OK to start taking data.

If you have been prompted to perform automatic parameter setup, hit the

object being tested with the hammer at the opposite side from where the

accelerometer is attached.
