Section 9: Archived Data - Displaying
Archived Data
SEASAVE can be used to display and plot archived data:
1. In the Archived Data menu, select Start. The Playback Archived Data
dialog box appears:
Note:
To display data without a mouse:
With the cursor in the main SEASAVE
window, press the Alt key to show the
keyboard shortcuts (underlines) on
menus. Press the appropriate letter (for
example, A for Archived Data menu)
and use the arrow and Enter keys to
navigate.
Data [.Dat or .Hex] File:
Currently selected data file is
shown. To select different file,
click Select Data File. The
Select Data File dialog box
appears. Browse to desired file
and click Open. To verify you
have selected desired file, click
Header tab to view data file
header.
Number of scans to skip
over at start: Skip scans at
beginning of data, allowing you
to skip data from before cast
began (i.e., when instrument
was on deck and initially
soaking in water).
If Read to end of file not
selected, enter total Number
of scans to read. This allows
you to view just a portion of file.
Data playback rate: Adjust
playback speed, simulating
real-time acquisition rate of
instrument, or speeding up /
slowing down. To simulate
real-time rate, set to CTD
acquisition rate (for example,
0.25 sec for 19plus). To display
at fastest possible rate, set to 0
(for quick creation of plots).
Save archived data setup (all parameters input on or
accessible through this dialog box, including .con and data file
names, number of scans to skip over at start, etc.) to buffer. If
you then save program setup (.psa) file, the next time you
select Start in Archived Data menu, Playback Archived Data
dialog box will appear with your saved selections.
Number of scans to skip between computations: Skip
data, speeding up display. To calculate/display all data,
set to 0. This interacts with update rate for each display.
Example 1: 19plus sampling every 0.25 sec
Number of scans to skip between computations = 4
Seconds between updates for display window = 5 sec
SEASAVE calculates parameters every 4 scans
(4 * 0.25 sec/scan = 1 sec), but updates display every 5 sec.
Example 2: 19plus sampling every 0.25 sec
Number of scans to skip between computations = 20
Seconds between updates for display window = 1 sec
SEASAVE calculates parameters every 20 scans
(20 * 0.25 sec/scan = 5 sec), and updates display every 1 sec.
Therefore, display shows same data 5 times before showing data
from next calculation.
Instrument Configuration [.CON]
File: Currently selected instrument
configuration (.con) file is shown. To
verify you have selected desired file,
select different file, or modify file,
click Instrument Configuration tab.
Start archived data playback.
Enable outputs selected in Configure Outputs: Send outputs
to serial port, shared file, TCP/IP port, and/or SBE 14 Remote
Display, as defined in Configure Outputs, as well as show data
in SEASAVE displays. If not selected, SEASAVE will show data
in its displays but not output data to any other device or file.
Note: Diagnostics log(s) enabled on Diagnostics tab in
Configure Outputs is automatically output, regardless of
selection here.
