Chapter 4 - Off Route Analysis with the dataPAC
Filter
The Filter parameter selects the filter used when collecting the measurement. These filters
are used for sound measurements. Your choices are:
z
None - The dataPAC does not apply a filter to the measurement.
z
ISO 2954 - The dataPAC applies an ISO 2954 filter to the measurement.
z
Sound A - The dataPAC applies an A weighting filter to the measurement.
z
Sound B - The dataPAC applies a B weighting filter to the measurement.
z
Sound C - The dataPAC applies a C weighting filter to the measurement.
Any measurement that uses these sound filters uses Xdcr Native Units of Other, a
Measurement Variable of Dynamic, and a Unit Text setting of Pa for Pascals of pressure.
Collecting an Off Route Overall Measurement
1.
After setting up the measurement, connect the proper transducer.
2.
Press <STORE> to start the measurement. The dataPAC ranges and collects the data.
3.
Once the dataPAC collects the measurement, press <STORE> again to save the
measurement. You can view the measurement in progress for as long as you wish
without saving. If you are in the minimum window, the dataPAC displays a small folder
with the number 1 in it after you press <STORE> to save the measurement. This
indicates that the dataPAC has saved the measurement. If you have Data Overwrite
enabled, only the data from the last time you pressed <STORE> is unloaded to your
database.
Note:
See “Selecting the Data Collection Options” on page 127 for more information about
the Data Overwrite option.
The measurement is stored as an off route measurement at the storage point displayed
below.
4.
Press <DONE> when you are finished. You can view the last measurement, if you
stored it, by pressing <F3> (Review Data).
