Header Form
SEASAVE can write a user-input descriptive header to the data file, which is
useful in identifying the data set. There are three choices for header use:
• Prompt for header information - The user will be prompted to fill out
the header form at the start of data acquisition. Only the lines with text
prompts on them will appear. The completed header, along with system
time, instrument type, and serial numbers, will be written to the beginning
of the data file and also output to a file with the same name as the data file
but with a .hdr extension.
• Include Default Header Information in File - The user will not be
prompted to add any header information at the start of data acquisition.
The user-defined default header form will be written as-is to the beginning
of the data file and also output to a file with the same name as the data file
but with a .hdr extension.
• Don’t Include Header Information in File – User-input header
information will not be added to the data file or placed in the .hdr file.
To set up the header:
1. In the Configure menu, select Header Form. The Header Form Setup
dialog box appears.
2. Select the desired Header Choice and enter the header. Click OK.
Example:
Prompt for Header Information is selected in the Header Form Setup dialog
box, and the Header Form prompts are filled in as shown.
Note:
A header is automatically
included in the data (.dat or .hex)
file and in the header (.hdr) file.
The header includes software
version, sensor serial numbers,
instrument configuration, date and
time of start of data acquisition,
etc. There can be up to two
date/time listings in the header.
The first, System Upload Time, is
always the date and time from the
computer. The second, UTC
Time, is the date and time from an
optional NMEA navigation device.
