E.3 BOTTLE SAMPLING IN FUNCTION OF THE SENSOR CONDITION
Bottles can be sampled in function of the sensor condition, when the probe is carrying out unattended
“Conditional cycles. When the foreseen condition is met, the bottles are fired according to a
configurable time delay. Bottles are closed starting from the first configured bottle to the last configured
one. The following message is shown by the probe once the conditional data acquisition function is
invoked and a Rosette is connected to the probe.
ROSETTE
Number of bottle positions: 12
Number of bottles to fire: 12
Bottle step: 1
First bottle to fire: 1
Reverse depth value: 1500.00
Bottle firing depth step: 100.00
Bottle firing time step: 00:00:00
Bottle firing depth profile: 1
Bottle firing method: CONDITIONAL TIME STEP
Do you want to fire bottles? Y(es, N(o
If the operator answers <NO>, the bottle will not be sampled. If the operator answers <YES>, the set-up
continues as follows:
Bottles position [1..36]
The operator must enter the maximum number of positions available on the interfaced Rosette.
Bottles to fire [1..36]
The operator must enter the number of bottles installed in the Rosette. It must be any value between 1
and the number of Rosette positions. The bottles are sampled consecutively starting from the first bottle
and ending with the last bottle, increasing the bottle number after each bottle sampling.
First bottle to fire [1..36]
The operator must enter the first bottle to fire. It must be any value between 1 and the number of Rosette
positions.
Step between bottle [1..36]
This allows the operator to define the number of bottle positions between two installed bottles. The step
value is used to advance the number of bottles in preparation of the next bottle to fire. The default value
is 1.
Bottle Trigger SENSOR logical code
A list of parameters that can be used to start the bottle firing is shown and the operator must select the
most appropriate one.
SENSOR trigger value
The trigger value which will be then used by the probe to start the firing bottle must be configured. The
value will be compared with the real-time reading taken by the probe. If the real-time reading is less
than the configured trigger value, the bottle firing process is activated. This will go on until the trigger
condition is met. Please be aware that the condition is evaluated only if the probe is acquiring data in
real time according to the “Unattended Conditional” measurement cycle set-up.
