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,
