Set-Up - idronaut Ocean Seven 304Plus Operator's Manual

SECTION THREE – COMMANDS

3.5.1. Set-up

The CTD "USER"configuration procedure allows to set up the following parameters:
OCEAN SEVEN 304Plus - Setup
Warm-up timeout [s]:0 <
Time-out to be spent at the CTD start-up to allow the sensor stabilization. It must be used when the
CTD interfaces oxygen and/or turbidity optional sensors (default values: 30s for oxygen and 5s for
turbidity).
Number of rows between headers [1..255]:22 <
This parameter defines the number of data rows shown by the CTD between header messages.
Default value is 22.
Under the "SERVICE" rights, the following additional parameters can be set.
16bit sensors measure to average:32 <
Optional sensors like: O2 and Turbidity data acquisition. Increasing the "measure to average"
decreases the noise and the number of measurements per second. The default value is 32. Below this
figure, the CTD performance, in terms of accuracy and resolution, cannot be guaranteed.
Turbidity Meter auto scale set-up [0..65535 ms]:800 <
Whenever the Turbidity meter is installed and the automatic scale management is active, this time-out
is spent when the measuring scale is switched to allow the Turbidity sensor stabilization.
Main com. port BPS: 0)9k6,1)19k2,2)38k4,3)57k6,4)115k2:2 <
CTD communication speed. Default value is 38K4. In case this parameter is modified, the ITERM
program communication speed must be modified too. The modification is applied at the successive
CTD start-up.
Battery low voltage limit [V]: 2.7
This limit represents the minimum battery operating voltage. Below the 2.7V limit, the CTD cannot
operate properly and its behaviour is unpredictable.
Under the "ADMINISTRATOR" rights, additional parameters can be set.
Note
Details about these parameters are out of the scope of this Operator's Manual. The improper modification of
these parameters could cause malfunction of the CTD. Contact IDRONAUT to obtain detailed information.
Now the CTD shows the list of acquirable sensors and associated derived parameters. This list is used
by the CTD to acquire, store and show real-time data. Up to fifteen parameters/sensors can be
configured, selecting them from the below list of possible sensors, parameters.
