acquisition and data storing. Before starting the profile, we suggest immersing in water the probe and,
wait at least 30s to stabilize the sensors.
2. When the probe returns to the surface, switch it OFF by means of the magnetic switch; data acquisition
ends immediately. The probe is ready to carry out a new profile.
The above operations can be executed repeatedly until the probe batteries have run down or until the
probe memory is full of data. Each time a data acquisition is performed, a new data header is
automatically generated.
C) Ending the unattended data acquisitions
1. Run the “ITERM” programme.
2. Switch the probe ON.
3. After the start-up messages, the probe starts by showing acquired data. Type ESC to stop data
acquisition answering YES to the given question.
4. The unattended timed acquisition is ended.
The acquired data is stored in memory and you can have a quick look at it by means of the functions
available in the "DATA STORAGE" menu.
3.15.2 Routine operations to perform unattended continuous profiles
Once the probe is switched ON by means of the magnetic switch, it starts to acquire data. Ending of
data acquisition is achieved once the probe returns to the surface and the operator switch the probe OFF.
Note
❖ The magnetic power ON/OFF switch can start and/or stop an unattended measuring cycle.
❖ Please be aware that, during the unattended continuous profiles, the probe does not reduce its
power consumption nor does it switch OFF by itself when back from a profile. To reduce the
power consumption, it must be turned OFF once on the surface.
❖ Please protect the not-in-use bulkhead connectors with the proper dummy connectors.
❖ When carrying out the unattended continuous profiles, the probe monitors the battery voltage.
In case it reaches the lower operating limits, the unattended profile immediately ends and the
probe switches OFF by itself. No other profiles will be accomplished. It is therefore important to
verify the battery conditions before starting a series of profiles.
❖ Each unattended continuous profile is stored in a different cast.
3.15.3 Terminate the Continuous data acquisition
The continuous data acquisition ends whenever one of the following events occurs:
Memory is full Whenever the data memory is full, the probe stops to acquire data and
automatically concludes the continuous data acquisition cycle.
Acquired data is automatically confirmed in the probe memory.
Battery has run down The probe automatically checks the battery voltage against the preset
boundary each time it wakes up or at regular intervals when it is always
ON. In case the battery has run down, the following message appears:
No more power supply to continue the continuous data acquisition
After this message is shown, the continuous data acquisition procedure
is automatically concluded and the probe shows the "Data acquisition”
menu again. Acquired data is automatically confirmed in the probe
memory.
Operator stops acquisition The operator can terminate the continuous data acquisition by pressing
the <ESC> key while the probe is ON or by pressing the <ESC> key once
