Selecting a Master for a Data Group
The scan timestamps of the instrument and module selected as the Master are used
to determine the time for each scan in the .csv data file. This is necessary when
you merge scan data from multiple instrument and module sources because the
timestamps from these different sources may not be exactly the same.
Scans from other sources are grouped with the matching master scan data. If all
instruments and modules have the same scan interval, it should not matter which
source is used as the Master, except that the data from the Master will be in the
first columns of the .csv file. When actual scan intervals differ between sources,
the scan data is handled as follows:
•
If an instrument or module scans slower than the Master, that slower source’s
data is repeated in the .csv file until a new scan is received from the slower
source.
•
If an instrument or module scans faster than the Master, only the scans from
the faster source that match the time of a Master scan are saved to the merged
.csv file.
Advanced Data File Configuration
Use the Advanced Data File Configuration dialog to create multiple groups of data
files. The configuration performed in the Data File Configuration window is stored
in the group that has the same name as the Fluke DAQ configuration file.
