Acquiring, Displaying and Saving Data in Real

Time

Once you have checked and configured a CTD-E, you can acquire, display, and save the selected

parameter data in real time by running the instrument directly from the test cable. See

Check-

ing and Configuring the CTD-E

for instructions on how to check and configure the instrument.

When ready to collect data, the test cable can be replaced with a sea cable for performing up

and down casts. See

APPENDIX C: Connector and Test Cable Wiring

for information on the

connector wiring. The data are displayed on graphics displays, and recording is directly to a

text file. During real-time data acquisition, CTDAcq also allows you to reset and fire a water

sampler.
This section provides instructions on how to run the CTD-E in three different real-time operat-

ing modes and how to display and save the parameter data. In addition, instructions are pro-

vided on how to reset and fire a water sampler, change the graphics display settings, and pre-

view and print the graphs.

Real-Time Operating Modes

There are three real-time data acquisition operating modes:

Profile mode

where data are continuously acquired, displayed and saved in

real time at

the selected sample rate.

Towed Acquisition mode

similar to Profile mode, but data are displayed

in a horizon-

tal format that is more suitable in towed applications.

Run Continuous mode

similar to Profile mode, but data are displayed in a digital dis-

play only, updated once per second, and can be saved in real time at the selected sample

rate.

NOTE. If an Average Length is entered as described in

Selecting to Average Collected Data

both the displayed and saved data are averaged data.

Acquiring Real-Time Data in Profile Mode

Data acquired in Profile mode are displayed on a cast graph and saved directly to disk. CTDAcq

creates three files for the data: a data (DAT) file with extension

.dat

, a calibration (C00) file with

extension

.c00

and a header file (HDR) with extension

.hdr

. All three files are in ASCII format

and can be opened and viewed in any text editor. They can also be input to CTDPost for pro-

cessing.
To acquire, display and save data in Profile mode:
1.  Connect the CTD-E to your computer and power supply.
2.  Choose Start
