Section 3: Configure Menu, Part I - General System Setup

Mark Variable Selection

Mark Scan allows you to copy the most recent scan of data to a mark (.mrk)

file as desired. The .mrk file can be used to manually note water sampler bottle

firings, to compare CTD data with data from a Thermosalinograph taken at the

same time, or to mark significant events in the cast (winch problems, large

waves causing ship heave, etc.) for later review and analysis of the data.

If a plot display is set up to show mark lines, SEASAVE will also draw a

horizontal line in the plot each time you mark a scan.

To enable and set up Mark Variables:

1. In the Configure menu, select Mark Variable Selection. The Mark

Variable Configuration dialog box appears:

Make the desired selections and click OK.

2. To set up a plot display to show mark lines - Right click in the desired

Overlay plot window, and select Setup. In the Display Setup dialog box,

select Show Mark Lines. Change other settings as desired, and click OK.

See Marking Scans in Section 7: Real-Time Data Acquisition to mark the

scans during data acquisition.

Note:

The .mrk file has the same file

name as the data file. For

example, if the data file is

test1.hex, the .mrk file is

test1.mrk.

Click to select desired variable.

A dialog box with a list of

variables appears; make your

selection and click OK. The

sequential mark number,

system time, and all selected

variables are written to the .mrk

file each time Mark Scan is

clicked during data acquisition.

Enter desired number

of digits to right of

decimal point for each

variable’s data.

Select Mark Type (line

can be labeled with

sequential mark number

or with pressure), Mark

Line Style, and Mark Line

Color, which are

applicable only if you set

up a plot display to show

mark lines.
