successive start-
up and until the “Stop Acquisition” character
is sent (CTRL-C), the CTD always
wakes up and starts to acquire data in function of pressure intervals.
Acquired data is automatically stored in the CTD memory. Consecutive acquisitions/profiles can be
done by switching ON/OFF the CTD. Each time the CTD is deployed, a new cast and data header is
created. A profile is considered completed when more than 5 measurements (i.e. 5 pressure intervals)
are stored.

Details of the linear configuration parameters can be found in section 4.0. Here is an example of the
messages sent by the CTD once it starts an unattended linear cycle:

WARNING
Please be aware that the configuration of zero or negative parameters could cause the CTD to behave in an
unpredictable way.
3.2.3.
Timed Profile
The CTD starts automatic unattended data acquisition in function of time interval. Once the set-up is
completed, the CTD switches off by itself and waits for the successive start-up. At the successive start-
up and until the “Stop Acquisition” character is sent
(CTRL-C), the CTD wakes up and starts an
acquisition. Acquired data is automatically stored in the CTD memory. A new cast and data header is
created at the first cycle. Successive data is associated to the open cast.
Time between consecutive measurements is spent in OFF condition with a negligible current
consumption (less than 8uA). The minimum interval time is 10 seconds.
An example of CTD configuration follows:
