Sampling rate Interval to configure
28 Hz 35 ms
20 Hz 50 ms
10 Hz 100 ms
5 Hz 200 ms
1 Hz 1000 ms
0.1 Hz 10000 ms
After the sampling rate has been entered, the probe is ready to start the conditional data acquisition
cycle. The following message appears on the PC screen:
Do you confirm the above ?:No type [Y]es or [N]o < y
Answer NO return to the data acquisition menu.
Answer YES the probe shutdown waiting the next wakeup to start the continuous data acquisition cycle.
----- UNATTENDED Conditional Acquisitions -------
To start the measuring cycle Switch OFF now the probe and then Switch it ON when ready
To stop while the probe is ON, type <ESC> until a message appears
Between acquisition cycles, while the probe is on surface, wait 1 minute before switching OFF the probe
Wait at least 30 seconds before executing a new Start-Up
Now, the operator must switch OFF the probe using the magnetic switch on the probe top cover.
Afterwards, when the probe will be switched ON to start the conditional data acquisition cycle when
the operator is ready to deploy the probe in the field.
Once switched ON, the probe starts to monitor the trigger condition according to the configured interval.
Note
If the probe interfaces a “Rosette” water sampling device, some questions about the water sampling method and
steps are presented to the operator. Details about the water sampling set-up can be found in the dedicated appendix.
3.14.1 Terminate the Conditional data acquisition
The conditional 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 conditional 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
in ON condition (burst measurements). In case the battery has run
down, the following message appears:
No more power supply to continue the conditional data acquisition
After this message is shown, the conditional 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 conditional data acquisition by pressing
the <ESC> key, while the probe is ON, or by pressing the <ESC> key
once the probe is OFF and answering positively to the question about
the intention to conclude the conditional acquisition cycle. In this case,
the following message appears on the PC screen after the start-up
procedure is concluded:
