Click “A(8) calculation” or, in the case of VDV, “Daily exposure calculation” to
calculate the vibration exposure (Figure 47). The result(s) will be compared with the
limits stated in the EU directive 2002/44/EC and are displayed in various colors:
black:
below exposure action value
purple: between exposure action value and exposure limit
red:
above exposure limit
During vibration exposure calculation a report is generated automatically. You can
find it in the worksheet “... Report”. It includes tables with the measured values and
the partial exposure values for each person and activity. Below you will find the vi-
bration exposure results for each person (Figure 48).
13.4. FFT Data Import to Excel
The FFT data stored on the VM31 can also be transferred to the Excel macro file.
Switch to the worksheet “FFT Import”. If previous FFT data is appears in the table,
please save the file under another name and click “Clear FFTs” to clear the table.
Then click “Import FFTs from VM31”.
The frequency steps along with the respective amplitudes of X/Y/Z are sorted into
table rows. You will see the date, time and comment for each record. Tick the check
boxes on the left hand side of each record to select which FFTs should be displayed
in the three diagrams above the table (Figure 49).
