(p. 16)). 3. Initial inspection Upon 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.
. 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.

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.
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.
6. Specifications Standards: Meets ISO 7027-1:2016 (side scatter) standard for turbidity measurements. Compliance: SDI-12 v1.4 Operating temperature range: –2 to 40 °C CAUTION: Sensor may be damaged if it is encased in frozen liquid. Power requirements: 9.6 to 18 VDC Power consumption Idle: <300 µA...
Shield U and C terminals 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.
Orient the unit so that the ClariVUE 10 looks into clear water without reflective surfaces. This includes any object such as a mounting structure, a stream bed, or sidewalls. The sidescatter sensor can see to about 5 cm (2 in) at 90°.
Page 12
Campbell Scientific recommends avoiding direct sunlight. The ClariVUE 10 measures any infrared light source pulsing at a 5 kHz rate that is in sync with the 5 kHz internal VCSEL light driver. Therefore, the combination of direct sunlight and a rippling water surface can affect turbidity measurements.

Use spacer blocks when necessary to prevent chafing the unit with the frame or the wire. Mounting inside the end of a PVC pipe is a convenient way to provide structure and protection for deployments. The ClariVUE 10 fits inside a 2-in schedule 40 PVC pipe. ClariVUE™10 Side-Scatter Turbidity Sensor...
8. Operation This section provides the following information: 8.1 Turbidity units 8.2 SDI-12 measurements 8.3 SDI-12 extended commands 8.4 Vertical-cavity surface-emitting laser diode 8.1 Turbidity units Conceptually, turbidity is a numerical expression in turbidity units (TU) of the optical properties that cause water to appear hazy or cloudy as a result of light scattering and absorption by suspended matter.
Procedures, describes the units: http://water.usgs.gov/owq/turbidity/TurbidityInfoSheet.pdf 8.2 SDI-12 measurements The ClariVUE 10 responds to the SDI-12 commands shown in Table 8-1 (p. 13). When the data logger issues an M! command, the sensor should respond immediately indicating how long it will take to perform the measurement.

8.4 Vertical-cavity surface-emitting laser diode The ClariVUE 10 sensor detects suspended matter in water and turbidity from the relative intensity of light side scattered at 90° in accordance with ISO7027. A 3D image of the main components of the sensor is shown in FIGURE 8-1 (p.

Maintenance, troubleshooting, and calibration NOTE: All factory repairs and recalibrations require a returned material authorization (RMA) and completion of the “Statement of Product Cleanliness and Decontamination” form. Refer to Assistance page at the end of this manual for more information.
5% send to Campbell Scientific for factory calibration (refer to Assistance for more information). 9.2 Troubleshooting 1. Check the wiring to ensure the ClariVUE 10 wires are connected to the correct data logger terminals (see Wiring (p. 7)).
Page 20
2. Wire sensor to the data logger. Many data loggers offer a terminal mode to talk to SDI-12 sensors. This procedure requires an SDI-12 recorder/data logger that can return multiple lines for an extended SDI-12 command. For this example, the ClariVUE 10 is connected to the following terminals on a Campbell Scientific CR1000X data logger.

5. Select the correct Communication Port and click Connect. 6. Click the Terminal tab. NOTE: Click Start Export to save the 25 verification readings in a text editor. This log can be easily transferred to a spreadsheet. Select All Caps to simplify entering the SDI-12 commands.
Page 22
ClariVUE 10 will need to equilibrate to the ambient temperature before doing the next step. 11. Submerge the ClariVUE 10 into the first calibration standard or DI water. Place the sensor vertically, in the middle of the calibration cup. If the first point is DI water or a turbidity standard less than 20 TU, use a black 8 liter (2 gallon) bucket, preferably tumbled so the inside of the bucket is not glossy/reflective.
Page 23
12. Type aXTEST!, where a is the sensor address (0 in this example). This SDI-12 command collects 25 measurements, which is similar to running the M! command 25 times in rapid succession. 13. If the values are stable, remove the sensor from standard 1. If you have it in DI water, cover the DI water bucket and go to the next step.
Page 24
14. Place the sensor in your second standard. If the turbidity value is greater than 20 TU, use a smaller calibration cup, preferably a black plastic container with a diameter greater than 4 inches. NOTE: The second standard should be within the range of the field site conditions or the range of turbidity in which you are most interested.

Appendix B. Factors that affect turbidity and suspended- sediment measurements This appendix summarizes some of the factors that affect turbidity measurements and shows how ignoring them can lead to erroneous data. If you are certain that the characteristics of suspended matter will not change during your survey and that your sensor was factory- calibrated with sediment from your survey site, you only need to skim this section to confirm that no problems have been overlooked.
than spherical particles, while angular shapes have intermediate scattering efficiency. Turbidity sensors are very sensitive to shape effects and this makes it very important to calibrate with material from the monitoring site. It is also essential that particle shape remains constant during the monitoring period.
SDI-12, Serial Data Interface at 1200 baud, is a protocol developed to simplify sensor and data logger compatibility. Only three wires are necessary — serial data, ground, and 12 V. With unique addresses, multiple SDI-12 sensors can connect to a single SDI-12 terminal on a Campbell Scientific data logger.
