UPLOADING THE DATA STORED IN THE PROBE MEMORY

At the end of any unattended acquisition, data stored in the CTD memory can be retrieved. The following
instructions explain how to do that by using the IDRONAUT Windows Terminal and REDAS-5 programs.

4.6.1. WINDOWS "ITERM"

 Run the "ITERM" programme.
 Connect the CTD to the personal computer using the USB laboratory cable and then switch ON the
CTD.
 The CTD main menu appears.
 Run the "identify" command available under the "CTD" menu of the ITERM programme.
 After the CTD has been identified, run the CTD upload cast from the ITERM "Probe" menu.
 Select the stored data and leave ITERM upload them for you.

4.6.2. WINDOWS "REDAS-5"

 Run the "REDAS-5" program.
 Connect the CTD to the personal computer using the USB laboratory cable and then switch ON the
CTD.
 From the REDAS-5 main menu, select the "REMOTE" sub-menu and then the "UPLOAD CAST"
function.
 REDAS-5 interrogates the CTD and retrieves the list of stored casts.
 From the shown list of casts, the operator can select the cast he intends to upload using the mouse
and the <SHIFT> or <CNTRL > keys.
 After the operator clicks on the OK button, the REDAS-5 programme starts to upload all the
selected casts automatically.

UNATTENDED ACQUISITIONS - IMPORTANT TIPS

4.7.1. Power consumption reduction

The CTD is equipped with a firmware protection to prevent the battery pack from running down. At
the beginning of the unattended acquisition cycles and at preset intervals during the unattended
acquisitions, the battery energy is monitored and compared against a configurable limit. If the battery
voltage falls below the configured limit, the unattended acquisition is immediately terminated.

4.7.2. ON/OFF cycles

Whenever you switch OFF the CTD, please wait 30 seconds before switching it ON again. This waiting
time allows the CTD to perform a correct start-up procedure.

4.7.3. Shipping conditions

The CTD is shipped without the battery pack installed. Recharge and install the battery pack before
carrying out any unattended acquisition cycles. Set up the CTD internal RTC date and time before
starting an unattended cycle.

4.7.4. Sensors

Depth sensor
Conductivity sensor After using the CTD in seawater, wash the conductivity sensor with fresh water
IDRONAUT – Brugherio (MB)
Before executing a data acquisition in relation to depth, proceed to calibrate (null)
the pressure sensor offset.
(preferably distilled water) thoroughly.
Do not leave the CTD exposed to direct sun light. Wet the conductivity sensor for
one night before starting the measurement campaign.
