1. Introduction
The ClariVUE™10 is a submersible turbidity sensor that uses side-scatter technology to measure
suspended solids and turbidity for applications ranging from water quality in aquatic ecosystems
to sediment transport and dredge monitoring.
2. Precautions
lREAD AND UNDERSTAND the Safety section at the back of this manual.
lThe sensor may be damaged if it is encased in ice. Damages caused by freezing conditions
will not be covered by the warranty.
lCampbell Scientific recommends removing the sensor from the water for the time period
that the water is likely to freeze.
lClariVUE 10 is a precision instrument that must be handled with care.
lIMPORTANT: Maintain a level of calibration appropriate to the application. Campbell
Scientific recommends factory recalibration of the ClariVUE 10 every two years or when it
varies by more than 5% in standard buffer within the 0 to 4000 TU range (see Verification
procedure (p. 16)).
3. Initial inspection
lUpon receipt of the ClariVUE 10, inspect the packaging for any signs of shipping damage,
and, if found, report the damage to the carrier in accordance with policy. The contents of
the package should also be inspected and a claim filed if any shipping-related damage is
discovered.

lWhen opening the package, take care to not damage or cut the cable jacket. If there is any
question about damage having been caused to the cable jacket, a thorough inspection is
prudent.
lThe model number is on the housing. Check this information against the shipping
documentation to ensure that the expected model number was received.
4. QuickStart
A video that describes data logger programming using Short Cut is available at:
www.campbellsci.com/videos/cr1000x-data logger-getting-started-program-part-3 .Short
Cut is an easy way to program your data logger to measure the sensor and assign data logger
wiring terminals. Short Cut is available as a download on www.campbellsci.com . It is included
in installations of LoggerNet,RTDAQ, and PC400.
The following procedure also shows using Short Cut to program the ClariVUE 10.
1. Open Short Cut and click Create New Program.
2. Double-click the data logger model.

3. In the Available Sensors and Devices box, type ClariVUE or find the sensor in the Sensors >
Water >Quality folder, and double-click ClariVUE5/ClariVUE10.SDI-12 Address defaults to
0. Enter the correct SDI-12 Address for the sensor if it has been changed from the factory
default value. Mean temperature defaults to degrees Celsius. These can be changed by
clicking the Mean temperature box and selecting a different option.
4. Click the Wiring tab. Click OK after wiring the sensor.
5. Repeat steps three and four for other sensors you want to measure. Click Next.

6. In Output Setup, type the scan rate, a Table Name, and Data Output Storage Interval. Click
Next.
NOTE:
Because of the sensor response time, Campbell Scientific recommends measurement
scans of at least 30 seconds.
7. Select the output options.
8. Click Finish and save the program. Send the program to the data logger if the data logger
is connected to the computer.

9. If the sensor is connected to the data logger, check the output of the sensor in the data
display in LoggerNet,RTDAQ, or PC400 to make sure it is making reasonable
measurements.
5. Overview
The heart of the ClariVUE 10 is a near-infrared (NIR) laser and a photodiode for detecting the
intensity of light scattered from suspended particles in water. The detector is positioned at 90
degrees to the emitter to measure the side-scatter energy. The ClariVUE 10 has two
measurement ranges. The low range is from 0-400 TU and uses a transfer function to convert mV
readings to turbidity units based on 4 calibration points in this range: 0, 20, 100, and 400 TU. The
high range is from 401 to 4000 TU. The high range transfer function converts millivolt to turbidity
units using seven calibration points across the full measurement range: 0, 20, 100, 400, 1000,
2500, and 4000TU.
Turbidity sensors are used for a wide variety of monitoring tasks in riverine, oceanic, laboratory,
and industrial settings. They can be integrated with water-quality monitoring systems,
conductivity, temperature, and depth sensors (CTDs), laboratory instrumentation, and sediment-
transport monitors.
Applications include:
lCompliance with permits, water-quality guidelines, and regulations
lDetermination of transport and fate of particles and associated contaminants in aquatic
systems
lConservation, protection, and restoration of surface waters
lAssessing the effects of land-use management on water quality
lMonitoring waterside construction, mining, and dredging operations
lCharacterization of wastewater and energy-production effluents
Features:
lFitted with wet-pluggable connector—multiple mating cable length options available
lAccurate and rugged
lCompatible with any SDI-12 data logger/controller including Campbell Scientific GRANITE-
series, CR6, CR3000, CR1000X, CR800-series, CR300-series, and CR1000

7. Installation
If you are programming your data logger with Short Cut, skip Wiring (p. 7) and Programming (p.
7). Short Cut does this work for you. See QuickStart (p. 2) for a tutorial.
7.1 Wiring
Connect the wires in the order shown in the following table.
Table 7-1: Wire color, function, and data logger connection
Wire color Wire function Data logger connection
White SDI-12 signal C,SDI-12, or Uconfigured for SDI-121
Red Power 12V
Black Power ground G
Clear Shield G
1Uand Cterminals are automatically configured by the measurement instruction.
If multiple SDI-12 sensors are connected to a data logger, Campbell Scientific recommends using
separate terminals when possible. However, multiple SDI-12 sensors can connect to the same
data logger control (C) or universal (U) terminal. Each must have a unique SDI-12 address. Valid
addresses are 0 through 9, a through z, and A through Z.
For CR6 and CR1000X data loggers, triggering conflicts may occur when a companion terminal is
used for a triggering instruction such as TimerInput(),PulseCount(), or WaitDigTrig().
For example, if this product is connected to C3 on a CR1000X, C4 cannot be used in the
TimerInput(),PulseCount(), or WaitDigTrig() instructions.
7.2 Programming
Short Cut is the best source for up-to-date programming code for Campbell Scientific data
loggers. If your data acquisition requirements are simple, you can probably create and maintain a
data logger program exclusively with Short Cut. If your data acquisition needs are more complex,
