    3. Initial inspection Check the packaging and contents of the shipment. If damage occurred during transport, immediately file a claim with the carrier. Contact Campbell Scientific to facilitate repair or replacement. Check model information against the shipping documents to ensure the expected products and the correct lengths of cable are received.

  • Page 5: Quickstart

    On cables and cabled items, the model number is usually found at the connection end of the cable. Report any discrepancies immediately to Campbell Scientific. 4.

    U and C terminals are automatically configured by the 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 or U terminal. Each must have a unique SDI-12 address. Valid addresses are 0 through 9, a through z, and A through Z.

Maintenance and troubleshooting 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 near the end of this manual for more information.

  • Page 31: Maintenance

    9.1 Maintenance To ensure reliable and accurate measurements, Campbell Scientific recommends doing the following every month: 1. Check the integrity of the cable and data logger connections. Replace cable if damaged. 2. Inspect the funnel for any damage or blockage. To clear a blockage, detach the funnel from the base, remove debris, then reattach the funnel.

  • Page 33: Internal Lithium Battery

    Table 8-3 [p. 20]). Replace the battery when voltage is approximately 2.7 VDC. Campbell Scientific recommends replacing the battery every two to three years and after each loss of power event. High temperatures can reduce the battery life, and low temperatures can decrease battery capacity, lowering available power and sensor runtime.

  • Page 34: Updating The Operating System

    Battery replacement procedure: 1. Loosen and remove the three base thumb screws, then lift the funnel upward. 2. Use a Phillips screwdriver to remove the four screws on the RainVUE-series interface. 3. Remove the interface cover. 4. Replace the old lithium battery with the new battery (3 V coin cell CR2032). 5.

  • Page 36 Symptom: Reported data values are lower than expected. Solution: 1. Ensure that the filter is clean and allows water to flow through it. 2. Check that the tipping mechanism can move freely. 3. Use a voltmeter on the switch to verify that the switch is activated as expected while transitioning from one side to the other.

  • Page 37: Appendix A. Importing Short Cut Code Into Crbasic Editor

    Appendix A. Importing Short Cut code into CRBasic Editor Short Cut creates a .DEF file that contains wiring information and a program file that can be imported into CRBasic Editor. By default, these files reside in the C:\campbellsci\SCWin folder. Import Short Cut program file and wiring information into CRBasic Editor: 1.

  • Page 38: Appendix B. Calibration Validation

    Appendix B. Calibration validation Use the XTEST! SDI-12 command to validate the calibration. Enter this command in the transparent mode while the computer is communicating with the data logger through a terminal emulator program. This command displays simulated rain fall data that does not affect rain accumulators used for the normal operation.

When the simulated rain is run through the gage at a fast rate, the number of tips may be lower than expected, but the corrected rain fall should be close to the actual amount of simulated rain.

  • Page 40: Appendix C. Sdi-12 Sensor Support

    Serial Data Interface at 1200 baud (SDI-12) 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.

    (no service request will be sent by the sensor). In transparent mode (see SDI-12 transparent mode [p. 44]), the user asserts this command to obtain data. Depending on the type of data returned and the number of values a sensor returns, the data logger may need to issue aD0! up to aD9! to retrieve all data.
