  • Page 11: Configuration And Scheduling

    Configuration and Scheduling Getting started with Ruskin Before you begin using your RBR loggers, you may want to experiment a bit with the simulated loggers that are included in Ruskin. For more information, see “Stop logging” on page 7. When you are ready to use your own RBR loggers, we recommend that you follow the following steps to ensure that you measure exactly what you want on the first attempt.
  • Page 12: Stop Logging

    For more information, see “Schedule a logger” on page 16. Ruskin prevents you from enabling a schedule that exceeds the memory capacity of the logger. Ruskin also shows the estimated battery usage (based on 1000 mAh cells) required to use your logger as scheduled.
  • Page 13: Use A Simulated Logger

    In the Navigator view, click the logger that you want. The Information tab in the • Properties view on the right side of the Ruskin window identifies the logger and the kind of sensors on its channels. Note: This is the only tab in the Properties view that you can access without any battery consumption, as indicated by the absence of a battery icon.
  • Page 14: Configure A Logger

    Configure a logger Before you enable a logger schedule, you can configure the logger to suit your requirements. The instructions to configure a TWR-2050 logger, which measures waves, are different. If your logger schedule is already enabled when you decide to change the configuration, you must stop running the schedule, make your changes, and enable the schedule again.
  • Page 15 Note: Although the data stored on the logger is of the highest precision, some precision may be lost if you use the data in the Plot view because Ruskin converts the data back to the raw format. 4. If you can see your logger case while it is deployed and want a visual indication that the logger is running, select the Enable sampling LED check box.
  • Page 16: Averaging

    If you want to specify a maximum time during which the logger can continue to store samples while the thresholding condition is no longer met, select the Enable hysteresis check box and specify the time period. Note that Ruskin enforces a hysteresis period that is a multiple of your sampling period (Schedule tab).
  • Page 17 Note that Ruskin enforces an hysteresis period that is a multiple of your sampling period. If you change the value of your sampling period, the hysteresis value changes to the same value.
  • Page 18: Configure A Tide And Wave Recording (Twr-2050) Logger

    Before you enable a TWR-2050 logger, you can configure it to better suit your requirements. This type of logger records data for tides and waves, and its configuration is different from that of the other RBR loggers. For information about configuring the other loggers, see “Configure a logger” on page 9.
  • Page 19 Note: Although the data stored on the logger is of the highest precision, some precision may be lost if you use the data in the Plot view because Ruskin converts the data back to the raw format. 4. If you can see your logger case while it is deployed and want a visual indication that the logger is running, select the Enable sampling LED check box.
  • Page 20: Relationship Between The Tidal And Wave Sampling Periods

    This value helps predict the range of wave frequencies that can be measured. In particular, read-only values for wave analysis bandwidth and wave periods will appear. Ruskin will calculate the actual depth from the measured pressure data post-deployment. You can now schedule your logger.
  • Page 21: Schedule A Logger

    You can schedule your loggers to start and stop taking readings when you want and at the sampling rate you specify for the sampling period. Ruskin indicates any unattainable conditions in the defined schedule at the bottom of the Schedule tab, and the Enable button is grayed out.
  • Page 22 You can either shorten your logging duration or lengthen your sampling period. 8. Note the actual memory required to use your logger as scheduled. Ruskin prevents you from running a schedule that exceeds memory capacity. If your schedule requires excessive memory, the memory bar indicator is red rather than green, and the Enable button is grayed out.
  • Page 23: Realtime Data

    Realtime data Fetching and streaming data The speed at which a logger takes readings and what it does with those readings depend on whether the schedule is enabled and whether streaming data is also enabled. Enabled without streaming You can enable a schedule without enabling streaming. The logger takes readings as scheduled at the speed specified in the Sampling period box.
  • Page 24: Download

    1. If you think that the connection to the logger will be at a low baud rate, perhaps due to a long cable, select the Slow Connection check box. Otherwise, Ruskin automatically increases the connection speed to the maximum possible during the download.

  • Page 31: Export Data

    Export data You may want to share your data with others or analyze your data using other software. You can export data as a text file, which can then be imported into many applications, or for analysis in Microsoft Excel or The MathWorks Matlab. You must already have downloaded the data to a dataset or opened an existing dataset.
  • Page 32: Save A Plot For Viewing Outside Ruskin

    By default, the file name for a dataset plot is that of the dataset with the appropriate file extension. The default file name for a plot showing live data follows the Ruskin file naming convention.
  • Page 33: N-Point Calibration

    N-Point Calibration RBR data loggers use several types of sensors that generate a voltage output that is proportional to the value of the parameter being measured. Ruskin will allow N-point calibration of these sensors, specifically dissolved oxygen measured by an Oxyguard sensor, pH, turbidity and depth in a TGR-1050HT.
  • Page 34: Oxyguard Do Calibration

    the appropriate calibration coefficients based on the data generated during calibration measurements. Oxyguard DO Calibration The Oxyguard DO sensor has relatively stable performance, and it can be calibrated with a single-point calibration technique using a reading at 100% oxygen concentration only. The 100% calibration should be performed at the expected temperature and salinity of the deployment environment.
  • Page 35: Amt Ph Calibration

    8. The Number of Samples field is automatically set to 100 samples. This value is the number of sample points Ruskin will use to calculate the calibration coefficients for the sensor. Typically, this value will be in the range of 50 to 100 samples.
  • Page 36 RBR uses pH 4 and pH 10 to measure the slope. Steps 1. Program the logger to sample at a fairly fast rate (between 6Hz and 3 seconds). Use Sync to PC to ensure the logger clock is synchronized to the PC clock, and ensure the end time is set so that the logger will keep sampling until calibration is complete.
  • Page 37: Seapoint Turbidity Calibration

    9. Ruskin will automatically calculate the calibration coefficients, and the values will appear in the four boxes at the bottom on the Calibration view. Clicking the Copy button will save the new calibration coefficients to the clipboard. 10. Follow the steps in Change calibration coefficients on page 27 to update the calibration in the data logger.
  • Page 38 8. Calculate value of the standard turbidity solution at calibration point according to following formula: = Tu ) = 49.38 FTU Where: = turbidity of the standard solution (FTU) = 4000FTU – turbidity of the stock solution = 100 ml volume of stock solution at calibration point (ml) = 8000ml - initial volume of distilled water Note: By using this formula and changing the volume of distilled water and Formazin solution, you can prepare different calibration points for checking linearity of the turbidity...

    3. In the Directory for log files box, type a directory name or click Browse to locate the directory where you want to store log files. Note: Log files are used when you request RBR support. 4. Click Apply or OK.
  • Page 43: Derived Channels

    Derived channels Derived channels contain calculated data based on data from measured channels. In the Derived Channels section of the Preferences dialog box, you can choose additional channels derived from measured channels. You can also set the salinity, pressure, and temperature values used to calculate the derived channels when a sensor is not available.
  • Page 44 4. If you want to derive a salinity channel using any XR-420/620-CT/CTD logger, select the Density anomaly (kg/m3) check box. Ruskin applies a correction to the density measurements that is calculated based on the UNESCO Technical Paper in Marine Science #44.
  • Page 45: Add Dissolved Oxygen As A Derived Channel

    Ruskin calculates the Specific Conductivity from Standard Methods for the Examination of Water and Wastewater (1989) Ch. 2, L. S. Clesceri et al Eds., American Public Health Association, Washington D.C., 17 6. If you want to calculate salinity using any XR-420/620-CT/CTD logger, under Salinity, select the Practical Salinity Scale check box.

    RBR generic serial card. Each serial card must be configured for the particular sensor using a meta table. Meta tables are set at RBR Ltd. before delivery. However, it may be necessary to change the meta table in the field and this tab allows the meta table to be viewed, edited and sent to the generic serial card.
  • Page 47: Meta Table

    Meta Table Channel number If there is more than one serial card in the logger you can select the appropriate card by selecting the correct channel number from the drop down list. Get table from interface Pressing this button retrieves the current meta table stored in the card and displays it in the Editor area.
  • Page 48: Test Meta Table - Sample Data

    Test Meta Table – Sample data Get data from sensor Pressing this button sends a command to all sensors asking them to perform a reading immediately. The resulting data is displayed in the Editor area. Editor Area In the editor area the meta table is displayed and can be edited. Messages are displayed from the application in a status box under the editor which indicate the success or failure of reading and writing meta tables.

    O-rings, etc. Please see the Ruskin User Guide section of this manual for instructions relating to logger programming and data retrieval. This manual can also be found on the distribution CD and on RBR’s website (www.rbr-global.com).
  • Page 50 The battery carousel is fastened to the assembly by a bolt through its centre. The carousel may be removed by twisting the bolt counter- clockwise until it is free. Access to the inner assembly may be obtained by unscrewing the sensor end cap.
  • Page 51: Changing The Batteries

    For a discussion of battery life expectancy, please refer to Appendix A - Battery lifetime calculation on page 52. RBR data loggers are powered by 2/3A size 3V lithium cells. These are standard camera batteries, and may be obtained from retail photographic or hardware outlets (see the following chart for model numbers).
  • Page 52: Communicating With The Logger

    TR-1060 loggers To remove the battery, first open the logger. The battery is held within its casing by the force of a single spring. Press firmly upon the negative end of the battery farthest from the spring and pull it out of the casing.
  • Page 53 Replacements may be obtained, but the cost is nearly five times that of a standard O-ring of similar size. Do not lose this O-ring. If you do, contact RBR for a replacement. Recent loggers are equipped with IE55 connectors and the following guidelines are provided: Lubricate mating surfaces with 3M Silicone Spray or equivalent.
  • Page 54: Deployment

    Stress due to improper mounting may cause the logger to leak, resulting in the loss of valuable data or permanent damage to the electronics. RBR can provide proper mooring and mounting clamps suited to your specific application.
  • Page 55: Maintenance And Repairs

    O-rings The single most important item of maintenance on any RBR submersible data logger is care of the O-rings. Any kind of water leak can damage the circuitry beyond repair and cause complete data loss. Every logger’s seal depends upon its O-rings, not the end cap tightness.
  • Page 56 If any of the surfaces of the O-ring groove are scratched, pitted or otherwise damaged, the logger may need to be returned to RBR for refurbishment: please contact us for advice. Replacing an O-ring Lever the O-ring from its groove. Use a soft plastic or wood tool; do not use a metal screwdriver or any other tool which may scratch the surfaces of the O-ring groove: doing so will probably render the end cap useless.
  • Page 57: Repairs

    RBR Ltd. will void the warranty. If it is necessary to return the product to RBR for an upgrade, repair, or calibration; please review the detailed shipping information on our website before returning the unit.

  • Page 60: Appendix C - Event And Error Stamps

    Appendix C – Event and Error Stamps The following is a list of event/error stamps that may be displayed in the data set. TIM - Time synchronization event STP - Stop sampling event GAN - Gain change event CHG - Change event (system restart where logger clock is no longer valid) WRM - Warm startup event (clock and programmed parameters are valid/unharmed) REC - Recovery event (problem with Real time clock.
  • Page 61 It is always accompanied by TIM timestamps showing the date/time both before and after the change was made, and a synchronizing timestamp with the sample data if necessary. This is not commonly seen, because RBR software does not permit date/time changes while the logger is sampling.
  • Page 62 This usually occurs only in instruments which are brand new or which have been reprogrammed or reconfigured, and is not normally seen outside the RBR factory. TTY indicates a serious failure of communication with the host, in which the logger was unable to send data over the serial connection because of an internal problem, although it may be able to recover later.
