1 SWiFT Profilers - Introduction
The SWiFT profiler is available in two main forms –SVP and CTD. The SVP is fitted with sound
velocity, temperature and pressure sensors, the CTD is fitted with conductivity, temperature and
pressure sensors. Configuration and data download is via dedicated Valeport Ocean software - PC
or mobile device and can be integrated into 3rd party software if required.
SWiFT SVP
SWiFT CTD
Designed from the outset for a seamless workflow, SWiFT profilers provide survey-grade sensor
technology coupled with the convenience of Bluetooth connectivity and rechargeable batteries, an
integral GPS module, to geo-locate each profile, completes the package. Data can be easily and
quickly downloaded and reviewed wirelessly, via Bluetooth, using the either Valeport's Ocean for
PC or mobile for portable devices and instantly shared, in industry standard formats through email
and cloud services. Alternatively, use the provided USB data and charging cable to connect to
Valeport’s Ocean software package.
In addition to the directly measured sound speed, temperature and pressure observations of the
SVP version, Conductivity, Salinity and Density are calculated using Valeport’s proprietary
algorithm developed from extensive laboratory and field work;
For the Swift CTD, sound speed, salinity and density are calculated from the Conductivity,
temperature and pressure data.
With a minimum battery life of 5 days continuous use, in profiling mode and the convenience of
charging via USB, SWiFT is intended for coastal, harbour and inland hydrographic survey use and
offers the highest quality profiles in a compact, robust and portable package.

3 Sensors
3.1 Sound Velocity Measurement
Utilising Valeport's latest sound velocity sensor, each measurement is made using a single pulse
of sound travelling over a precisely known distance, so is independent of the inherent calculation
errors present in CTD calculated data. Valeport's unique digital signal processing technique
virtually eliminates signal noise, and gives almost instantaneous response; the digital
measurement is also entirely linear, giving predictable performance under all conditions.

3.5 Optical Sensors
An optical sensor must be kept clean to operate correctly. Ensure that the SWiFT plus is powered
down before cleaning the sensor.
Use warm soapy water with a soft bristled brush to remove any light fouling.
For heavy fouling use a solvent (e.g Isopropyl alcohol) and a soft bristled brush.
Always rinse thoroughly after every use in clean, fresh water.
3.5.1 Fluorometers
3.5.1.1 Safety Statement
A Valeport Fluorometer is classified as Risk Group 1 under standard 62471. As the type is
classified as Risk Group 1 solely due to radiation in the visible band a hazard label is not required.
However,
•the LED used is in excess of the Exempt Group and that the viewer-related risk is
dependent upon how the user installs and operates the equipment.
•The exposure hazard value (EHV) for a Valeport Fluorometer in terms of distance is
320mm.

3.5.1.7 Linear Observation Range
The linear range is the concentration range for which the fluorometer signal is directly proportional
to the concentration of the fluorophore. The linear range starts at the minimum detection limit
(MDL) and extends to the upper limit of the instrument (dependent on fluorophore properties,
optical filters, LED power, sample volume and optical path length).
The optical devices manufactured by Valeport have digital outputs only; at higher concentrations,
unlike analogue devices which generally flat-line at full-scale deflection (e.g. FSD 5V) the
fluorometer will continue to output a signal which increases with concentration (i.e. meaningful
data), though which is no longer guaranteed to be linear.
At very high fluorophore concentrations, signal quenching can occur, whereby the instrument
output does not increase linearly with fluorophore concentration (roll-off) and may decrease at
even higher levels.

To perform a quick linearity check, dilute a sample of dye 1:1 with RO water. If the reading
decreases by 50%, the sample is in the linear range. If the reading decreases by less than 50% or
even increases, the sample is above the linear range.
3.5.1.7.1 Quenching
Quenching refers to the reduction in fluorescence of a fluorophore. Several processes can result
in quenching:
Chloride is known to quench quinine sulphate and Fluorescein. It is, therefore, advisable to
prepare any fluorophore solutions with Reverse Osmosis (RO) or De-Ionised (DI) water.
Temperature quenching - as the temperature of the sample increases, the fluorescence decreases,
that is, fluorescence is sensitive to temperature. In order to improve accuracy, measure the
sample at different temperatures and derive corrections for changes in temperature.
Photo-bleaching (or fading) is the (permanent) degradation of a fluorophore molecule by light
resulting in lower signal levels. Photo-bleaching is dependent on exposure (intensity of light and
duration) and wavelength (UV is more damaging than longer wavelengths). Use of more robust
fluorophores is recommended to avoid photo-bleaching.

3.5.2 Turbidity
Valeport's Turbidity technology is essentially two sensors in one. The first is a “classic”
nephelometer, using a 90˚ beam angle for turbidity levels between 0 and 2000 NTU. The second
sensor uses optical backscatter - OBS (~120˚ beam angle) for turbidity levels beyond 10 000 NTU.
Both sensors output data simultaneously, at a programmable rate, so there is no need to switch
ranges as conditions vary. Intelligent sampling and the use of a 24 bit ADC eliminates the need to
switch gain. The optical head is very compact, measuring just 20mm diameter and is rated to full
ocean depth.
Excitation\Detection:
850nm
Linear Range:
Nephelometer 0 to >1 000 NTU - linear response
Optical Backscatter: 0 to 4 000 NTU - linear response
(>4,000 NTU has a non-linear monotonic response that allows
derivation of higher values using look-up tables)
Minimum Detection Level
0.03 NTU
3.5.2.1 Safety Statement
The Turbidity sensor is classified EXEMPT under the standard 62471.
As a Valeport Turbidity sensor is classified as EXEMPT a hazard label in not required.
Never look directly into the optical aperture

3.7 Operational Battery Life
It can be assumed that a SWiFT SVP and SWiFT CTD use a similar amount of energy during
operation. For the SWiFTplus calculations a worst-case scenario is used –Chlorophyll a.
These calculations are an indication only and actual performance will depend on a number of
factors not modelled in this calculation.

5 Rechargeable Battery
The SWiFT is fitted with a rechargeable battery with the following characteristics:
Battery:
Internal, Rechargeable Lithium Ion Battery Pack
Capacity
Total Capacity 12Ah. Available Capacity: 10 Ah
Charging:
USB
1.5A Charger that is supplied
0.5A Laptop USB port
Battery Life:
Up to 5 continuous operation from a fully charged pack (standard SWiFT)
As the battery becomes discharged the SWiFT status LEDs will change during operation:
Solid Green

Solid Amber
less than 24 hours but more than 12 hours
Solid Red
Less than 12 operational hours
The actual number of operational hours can vary from one project scenario to another and if a
SWiFT plus is being used. Environmental factors have to be considered as well as the age of the
battery, the time the SWiFT is switched on as well as the time in the water all have to be taken into
consideration.

5.1 Charging
The battery pack is supplied with a dedicated USB charging and data download interface cable,
this must be used.
In order to gain access to the charging socket the lock nut and suspension spar must be removed -
see illustration on the inside of the transit case lid. Pay special attention to the O ring seals during
dis-assembly and most importantly reassembly to insure a fully water tight seal. When replacing
the suspension spar and lock nut do not over tighten either thread. Finger tight is tight enough.
The suspension spar contains a vent hole in case of pressure build up in the housing. This venting
hole must be kept clean and clear. If the SWiFT is used in a manner not specified by Valeport the
protection provided by the equipment might be impaired.
The supplied USB charger is capable of charging the
battery with a 1.5 A current.
The battery pack has intelligent charging and discharge
circuitry. There is no 'memory' to the pack so partial
charging sessions will not reduce the capacity or life of the
pack. The capacity of the pick will, however, reduce with
age.
It is advised that the SWiFT battery is never allowed to
become fully discharged. In a fully discharged state the
battery is open circuit. In order to reduce the chances of
battery becoming fully discharged the SWiFT will disable
all sensors with 1 hour's operational charge left. From
disabling the sensors, you have approximately 100 hours
to start a charging session to prevent the battery becoming
open circuit.
If the battery is completely discharged and, therefore,
open circuit it will take 50 minutes, using the supplied 1.5A
charger, to start taking on a charge. Please note, during this 50 minute period of charging no
LEDs will be lit.
If charged for 1 hour from a near flat but not an open circuit state, using the supplied 1.5A charger,
the battery will take on a charge that will allow the SWiFT to operate for approximately 12 hours.
It will take approximately 12 hours, using the supplied 1.5A charger, to fully charge the battery from
a near flat but not open circuit state.
When the charging session is complete, disconnect the charging cable from the SWiFT before
disconnecting power from the charger.
5.1.1 Charging Status
During charging the status of the process can be monitored:
Flashing Red
Charging < 12 hours capacity
Flashing Amber
Charging at > 12 hours capacity < 24 hours capacity
Flashing Green
Charging > 24 hours capacity
Solid Green

5.1.2 Charging from a Laptop USB Port
A typical Laptop USB port is rated to supply up to 0.5A for charging, although many newer laptops
have dedicated USB sockets (usually marked yellow) that often are capable of higher output
currents. The SWiFT’s electronics is able to detect the higher current available resulting in faster
charging cycles. The SWiFT also maintains the maximum charge voltage at a reduced level,
resulting in longer battery life.
Any charging operation from a standard USB port will take approximately three (3) times longer
than if the supplied 1.5A rated charger is used as described above.
5.1.3 Battery Life Expectancy
The batteries installed in the SWiFT will lose capacity over time. Lithium-ion batteries use the
movement of ion particles to create and store an electrical charge. Eventually these ion particles
are trapped and can no longer move around. The batteries then lose their capacity to store
energy.
Under normal operational conditions the SWiFT battery pack should offer a practical, usable
capacity for a period in excess of 4 years.
