Tips for setting the measurement parameters
Set the 'Trigger Start" time to a negative value in order to record
the signal before the excitation.
If the measurement starts before the excitation, increase the trigger
threshold in the measurement setup by approximately half (P. 3-22).
If the response signal overloads, increase the 'Measurement Range'
parameter in the measurement setup accordingly (P. 3-22).
Note
Measurement with the machine running
• Enable 'Negative averaging' in the measurement setup.
• Perform the individual impact tests.
• Click on 'Start' in the window that opens to measure the reference
spectrum - without producing a machine excitation!
• Click on 'Stop' when a sufficient number of reference spectra have
been recorded and averaged to form a result.
Displaying the results
• Activate the upper display field with the F key (Spectrum, P. 4-8).
• Press the MENU key and click on 'Choose Dataset'.
The results of the impact test, the average final result and the
reference measurement (negative averaging) are listed here and
can be displayed individually by clicking (see below).
• To close the list, press on the ESC key.
Repeating individual measurements
• Activate the upper display field using the F key.
• Press the MENU key and click on 'Repeat'.
• Click on the respective measurement in the list.
