2. Predicting battery life Battery life prediction is a complicated issue In RBR loggers battery life is a strong function of the type of logger the type and number of sensors attached the sampling scheme sampling period and the use of thresholding real time data collection and averaging and the temperature of the water during the deployment Manufacturers data for the batteries do not provide information that can be directly related to way the batteries are used in RBR Loggers The Ruskin Software calculates the expected battery usage in mA Hours mAh for the logger during setup see Ruskin User Guide The nominal capacity of the batteries is 1300mAh at room temperature The software will warn the user if the expected battery usage for a particular deployment scenario is above 1000mAh The software will not prevent a logger from being started even if a warning is given In tests at RBR Ltd of multiple examples of various brands of batteries at 6 C all examples were able to provide the threshold capacity of 1000mAh The user should view these predictions and further de rate the batteries if the expected deployment is in cold water The battery usage estimate is stored as part of the log files and may be used after deployment to enable the user to obtain a characterization of how a particular logger performs RBR continues to characterize battery life in its loggers and will continue to improve the battery life calculator in futur

CAUTION 1050 and 2050 series loggers To remove the batteries first open the logger The batteries are held within their casing by the force of a single spring Press firmly upon the negative end of the battery furthest from the spring and pull it out of the casing XR loggers To remove the batteries first open the logger and remove the battery carousel The batteries can easily be slid out of the carousel When inserting new batteries ensure that they are correctly oriented the yellow markings at the end of the battery carousel indicate the direction towards which the positive terminal of the battery should be placed The logger will not work if the batteries have been inserted improperly 46 November 5 2010 Rev1 4 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 When inserting a new battery ensure that it is correctly oriented The positive terminal of the battery should be placed toward the spring the marking on the bottom of the battery carousel indicates this direction The logger will not work if the batteries have been inserted improperly Communicating with the logger 1050 2050 and XR series loggers Using the internal data port November 5 2010 To establish a link between the

O ring on 1050 2050 and XR loggers O ring on TR 1060 loggers O rings must be undamaged and the mating surfaces free from particles of grit hair or small scratches in order to preserve a seal Before deploying the logger carefully inspect the O rings that are required to maintain a seal 1050 2050 series loggers depend upon one O ring in the end cap The plastic XR series of loggers have one O ring for each end cap and two for each detachable sensor Titanium versions of the XR series loggers have a backup ring in each end cap as well TR 1060 loggers have one O ring seated in the middle part of the logger case Give particular attention to the following areas e The surface of the O ring itself November 5 2010 50 Devi A e The mating surface on the inside of the case between the threads and the open end e The inner surfaces of the groove in the end cap where the O ring sits e The mating surfaces for each removable sensor e The underwater connector for external power or data transfer if used Any dirt present should be removed by wiping thoroughly with a soft lint free cloth When cleaning never use any material or tool which could scratch the O ring or any of its mating surfaces If any dirt is present in the O ring groove then the O ring should be removed as described below to allow thorough cleaning of the groove If an O ring needs to be removed for any reason it should be replaced If the O ring is scratched cut distorted

8. 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 N Place the probe into buffer solutions of values 4 7 and 10 for approximately 10 minutes in each solution Remember to make note of the time for each of the sample points so that the correct data can be used to determine the calibration coefficients Note Ensure that the pH sensor is rinsed with clean water between each sample reading to avoid contamination between buffer values Gei Retrieve the data from the data logger as per the steps in the Download section on page 19 of this manual Make sure that a copy of the data is saved as well 4 The calibration data should now be displayed in the Plot view Click the Calibration tab in the Properties view to the right of the Plot view oO Select the pH sensor type from the drop down menu If the data logger has multiple sensors the Plot view will automatically update to only show the channel being calibrated 6 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 For the pH sensor this value will typically be 25 samples 7 To set the first point in the slope m
