Data
The Vector creates binary files (*.vec), which can be converted to ASCII format files by using the
Data Conversion tool within the Vector software. The Vector records the following:
The *.hdr file is a self-documented table. Please note that this file contains the detailed data
format of all the other ASCII files.
The *.dat files contains velocity and pressure data at the full sample rate.
The *.sen files contains system data such as the time/date, compass, tilt, temperature, battery
voltage, etc. These data are sampled once per second
The *.pck contains the probe check data
The *.vhd contains the Velocity header data - the data that is collected during the very first second
when running Continuous mode, or at the start and end of each Burst.
The ASCII files are easy to import into most spreadsheets and data analysis programs.

data analysis and related matters.
Quality Assurance and Quality Control Tips:
Check the Looking at Velocimeter Data section. If the data looks different from what you expected
and you have reason to believe that this is instrument or deployment related, consult the
Troubleshooting section before spending too much time on QA/QC.
