Sea-Bird Scientific Deep SeapHOx V2, User Manual

Page: 22 / 56

The standalone SeaFET operates continuously user-selected intervals from 6 to
21600 seconds. Data is transmitted in engineering units.
5.1 Deployment orientation
When deployed as a stand-alone sensor, the orientation of the SeaFET should be based
on the deployment site conditions. Light exposure to the ISFET could cause errors in the
data, so in high-sun areas, it is best to deploy the sensor with the wet cap pointed down.
Errors in data can also occur from bubbles that collect on the sensing elements. In areas
where there are many bubbles, deploy the SeaFET with the wet cap pointed up or
horizontally.
The SeapHOX should always be deployed with the wet cap pointed up.
5.2 Configure sensor with deployment wizard
The deployment wizard in the UCI software makes it easy to set up and configure the
sensor for a specific deployment.
With the sensor connected to a power supply (or internal batteries if so equipped) and a
PC that has the UCI software installed, start the software, turn on the power supply, start
communication with the sensor and push
Deployment Wizard in the Dashboard.
Autonomous operation mode
1. Push Synchronize SeaFET clock to computer . The sensor and the PC show the
same time. Put a check in the box to erase all of the data stored in the sensor and set
the event counter to 0 when the deployment starts.
2. Set the date and time for the sensor to start data collection.
3. Transmission: put a check in the box to send collected data in real time to a
connected controller. Data is still stored in the sensor if this box does not have a
check in it.
4. Pump Settings : put a check in the box to enable operation of an external pump.
Values can be between 0–255. If set to 0, the pump will operate continuously.
5. Calculate Battery Endurance . This calculation uses an estimate of the voltage of
new batteries. It does not measure voltage directly.
a. Enter the temperature of the water in which the sensor will be deployed.
b. Enter the sample interval (40–21600).
6. Make a deployment report to see sensor statistics, calibration values, and settings.
Polled (controlled) operation mode
1. Push Synchronize SeaFET clock to computer . The sensor and the PC show the
same time. Put a check in the box to erase all of the data stored in the sensor and set
the event counter to 0 when the deployment starts.
2. Current Output Format shows the order of the data values from the sensor.
3. Calculate Battery Endurance . This calculation uses an estimate of the voltage of
new batteries. It does not measure voltage directly.
a. Enter the temperature of the water in which the sensor will be deployed.
b. Enter the polled interval (1–86400).
4. Make a deployment report to see sensor statistics, calibration values, and settings.
