SECTION 1 INTRODUCTION BOD Analyst software ™ for Windows™ (BOD Analyst software) is a Windows-based PC software accessory to the YSI 5000 and 5100 Dissolved Oxygen Instruments. Once you have defined your particular BOD application in the software, it will be able to control the YSI 5000/5100 Dissolved Oxygen Instrument and help to automate your BOD readings.
Introduction Section 1 Click OK to proceed. The installation program will then display the following screen. Click the button with the picture of a computer to begin the installation. From this point, the installation program prompts you to place the BOD Analyst software disks in the disk drive. Simply follow the instructions on the screen to complete the installation. Upon completion of the installation, a program group with a BOD Analyst software icon will be setup.
Introduction Section 1 The Bench sheet is the main form of the BOD Analyst software. From the bench sheet all functions of BOD Analyst software are found. A day’s batch is retrieved into the bench sheet so the DO readings can be taken, the BOD’s calculated, the criteria applied to the tests, and the Final BOD stored. Data is stored in a Microsoft Access database, by default the database is data.mdb. The current database is displayed in parentheses in the BOD Analyst software title bar.

Introduction Section 1 Coefficient of Variation Limit Apply Criteria after Final Readings 0.35 On Step 2: Setup Samples Next, you have to setup the Samples you run in the BOD Analyst software. BOD Analyst software by default has the DilBlank, Seed, and Standard Samples setup. From the Main Menu, choose Setup, Samples to add your samples and review the default samples. See Section 2, Samples for more information.
SECTION 2 SAMPLES 2.1 WHAT IS A "SAMPLE?" With YSI’s BOD Analyst software you can organize your work by sample. A sample is anything for which you want to know the BOD.
Samples Section 2 In this example, there are two dilutions: 150ml and 275ml. This Sample is seeded with 3ml of material taken from the Influent. 2.2 USING SAMPLE SETUP The Sample Setup Form is used to add new Samples to the database or to change old ones. The Sample Setup Form is accessed from the menu by selecting Setup, Samples. Sample Setup information is used as defaults when adding a sample to a day’s batch. For example, we setup Influent with three dilutions of 5, 8, and 10 ml and no seeding.
Samples Section 2 Dilution Setup: You can have up to 5 dilutions for any Sample. On the General Setup Form, the dilution unit field allows you to choose to express your dilutions in milliliters (ml) or in percent (%). If you change dilution units on the General Setup Form, all of the dilutions in each of your Samples will be changed automatically to reflect the new units.
Samples Section 2 Quality Control: Used in the trending graph function to display Quality Control Limits on the graph for the sample. 2.4 CHANGING A SAMPLE Use the button bar to move to the sample (record) you want to change. Edit the fields as required. Changes are automatically saved. Keep in mind that editing a Sample name will cause the new name to appear even on reports of old data.
Samples Section 2 You can find a detailed description of the abbreviation algorithm in the next section. The only thing that you need to remember is that characters at the end of the name will be the first to go. 2.5.1 ABBREVIATION ALGORITHM The abbreviation algorithm is simple. It attempts to remove the least important characters first, removing one at a time until there is room for the dilution and the new abbreviated name. It starts at the end of the Sample name and moves back.
SECTION 3 SEEDING SAMPLES 3.1 WHY SEED? Seeding is necessary when there are not enough bacteria present in the sample. A small amount of seed material that is known to have adequate bacteria is added to the bottle along with the aliquot and dilution water. Seeding is most often necessary with an effluent sample that has been chlorinated. The seed material can come from the plant's influent, from some intermediate point in the process, or from commercially available seed packets.
Seeding Samples Section 3 If you seed directly to the bottle, the amount of seed material in each bottle will simply be the seed quantity. If you seed the blank water, the amount of seed material in each bottle depends on how much dilution water is in that bottle. Note therefore, that your choice of method will affect the calculations. You may, after some time, decide that it would be best to change your seeding method.
SECTION 4 SAMPLE GROUPS 4.1 WHAT IS A "SAMPLE GROUP"? A Sample Group is a set of samples. For brevity, we often refer to Sample Groups as simply Groups. You will want to define a Group for every set of samples that you do frequently. Groups allow you to bring a number of samples into a Batch quickly and easily. A Group definition includes a name, a description, and the sample names of the group. You will want to list the Samples in a Group in the same order that you typically measure them.
Sample groups Section 4 NOTE: The dilution blank sample is automatically added when you build a batch. Therefore, you do not need to add the dilution blank sample to any group. 4.4 CHOOSING SAMPLES FOR GROUPS The Choose Samples list displays all available samples. The Samples in Group list displays the samples that are in the Group. Use the transfer buttons described below to add or remove samples from the Group. Transfer all selected samples from the Choose Samples list to the Samples in Group list.
SECTION 5 BATCHES 5.1 WHAT IS A "BATCH?" A Batch is all initial DOs that are done on any one day, along with their corresponding final DOs. Because there is only one Batch per day, we can refer to a Batch by the Sample Date. It is very important that the date on your computer is correct. The date when you read the initials and the date when you run the finals set the incubation period for the batch. If the date on the computer is incorrect, the BOD Analyst software may not calculate the BODs correctly.
Batches Section 5 The Open Batch Form can also be used to delete a batch. Select the batch to be deleted and click [Delete]. You will be asked for confirmation before deletion. 5.3 THE BUILD BATCH FORM From the bench sheet, when a Sample Date is entered that has no batch setup for it, the build batch form will be displayed. The build batch form is used to specify the samples and their dilutions for the batch. The table on the Build Batch form describes the batch. Each line in the table is a Sample.
Batches 5.4 Section 5 WORKING WITH BATCHES 5.4.1 STEPS TO BUILDING A BATCH Add the samples for the batch by: 1. Click on a group in Choose Groups and then click to add all the samples for the group to the batch. You can also drag and drop the group onto the batch to add the samples to the batch. OR Click on a sample in the Choose Samples and then click batch. You can also drag and drop the sample onto the batch. to add that sample to the 2. Use to change the order of the samples.
Batches Section 5 5.4.5 IMPORT BATCH This feature allows you to setup a batch by importing a text file created in another system (i.e. a LIMS). The LIMS needs to build a file with the sample names followed by an optional serial number, one pair per line. Sample names in the file must exactly match sample names defined in BOD Analyst software (however, Sample names are not case sensitive).
Batches Section 5 dilution oxygen depletion, seed correction factor and BOD are calculated automatically. For each set of tests having the same sample name, a Final BOD is found by averaging BODs for the sample. When tests are checked for validity, the Final BOD is automatically recalculated using only those tests that meet the criteria. 5.5.2 MARKING/UNMARKING Tests can be checked for validity using limits set in Criteria Setup.
Batches Section 5 Select the sample to add from the list and the number of dilutions and the dilution volumes will be read from the sample setup. Edit the Sample’s dilutions and Seeding information if required and click OK. Changing the dilution and seeding information on this form only changes it for this batch. The sample and its bottles will be added to the end of the batch. 5.9 MARKING A BOTTLE This button marks tests independently of the current criteria.
Batches Section 5 Notes: Used for any miscellaneous notes for the entire batch. Bottle Notes: This field allows entry of bottle specific notes. As the cursor is moved around the bench sheet the notes for the current bottle will be displayed. This allows users to enter the pH of the bottle if it is required by the state. 5.13 COLUMN DESCRIPTIONS Sample Name: Identifies the sample. Bot tle #: The number of the BOD bottle used for incubation. Pre Dil: The pre-dilution ratio for the bottle.
Batches Section 5 5.14 DELETING A BOTTLE To remove a bottle from a batch, click on the row header and press the delete [del] key. To select multiple bottles for deletion, click on the row header and drag the mouse to highlight multiple rows. With the rows highlighted, press DELETE and all the highlighted rows will be removed from the batch. The DilBlank Sample cannot be deleted from a batch.
SECTION 6 TAKING INITIAL DO READINGS 6.1 ENTERING BOTTLE NUMBERS 6.1.1 USING THE YSI 5000/5100 DO INSTRUMENT Just after selecting Read / Initials from the menu, the YSI 5000/5100 DO Instrument display will look like this: Begin taking Initials? To begin taking measurements, press CONFIRM. You will then move onto the bottle number prompt for either the first bottle in a new Batch, or the next bottle to be done in an interrupted Batch. Here is the bottle number prompt for an Effluent Sample.
Taking Initial DO Readings Section 6 Effluent 60 i Enter bot#29 then press CONFIRM. Effluent 60 i Enter bot#290 To enter "4" for the last digit, press the up arrow 4 times, then CONFIRM. The SKIP button is used like backspace during bottle number entry. Before pressing CONFIRM on the last digit, pressing SKIP will move you to the previous digit so you can change it with the UP and DOWN button. After the last digit of the bottle number is entered, the program will continue reading dissolved oxygen.
Taking Initial DO Readings Section 6 You can also move between dilutions (bottles) without going through the batch sequentially. The SKIP, UP, and DOWN buttons can be used to navigate through the batch. SKIP Moves to the next bottle (dilution). UP Moves to the first dilution of the previous sample DOWN Moves to the first dilution of the next sample Note: The SKIP, UP, and DOWN buttons provide different functions when entering bottle numbers and will NOT move to a different dilution.
Taking Initial DO Readings Section 6 You do not have to do the final DOs in the same order as you did the initials. If want to do some other bottle number than the one for which the prompt appears, simply scan that other bottle, and the program will jump to that bottle in the Batch. 6.1.3 USING A PC KEYBOARD You can use the PC keyboard to enter the bottle numbers on the benchsheet before beginning initial readings, or use the keyboard to enter the bottle numbers as you work.
Taking Initial DO Readings Section 6 The fastest and easiest way is to set Technique: to auto. After the bottle number is entered the program will store the reading as soon as it is stable. Entering the bottle number then, is an implied confirmation of the soon to be stable reading. 6.3 ALARMS Alarms are provided for temperature and supersaturation. You can specify a range of temperatures for initial DOs and a different range of temperatures for final DOs.
Taking Initial DO Readings Section 6 Now, we will want to measure only one of the dilutions of the Influent Sample and derive the other two. There is less experimental error if you measure the strongest dilution. You will have to enter bottle numbers for all three dilutions.
Taking Initial DO Readings Section 6 You don't have to derive initial DOs for every Sample in the Batch. For instance, you may derive initials for only those Samples that are not required by your NPDES permit. All you need to do is skip all those dilutions that you want to be derived and measure all the dilutions that you don't want derived. You can measure more than one of the dilutions for any Sample.
SECTION 7 TAKING FINAL DO READINGS 7.1 SELECTING A BATCH From the main bench sheet window, simply enter the sample date for the batch you would like to take readings for. Alternatively, click the List Open Batches button (See Section 5.2, Loading a Batch for more information) to select a batch that is not yet complete. The batch will be displayed. Below is an example of a batch ready for final DOs to be read. 7.2 AT THE YSI 5100 DO INSTRUMENT Select Read/Finals from the BOD Analyst software Main Menu.
Taking Final Dos Readings Section 7 Your Technique for Auto Stabilize setting affects how the BOD Analyst software responds to your input. Auto: The YSI 5000/5100 DO Instrument will automatically store the DO reading when the reading becomes stable. Dual: After the reading is stable, press CONFIRM to store the reading. Manual: Press CONFIRM to transfer the current DO reading from the YSI 5000/5100 DO Instrument. The YSI 5000/5100 DO Instrument will display STBL when the reading becomes stable.
Taking Final Dos Readings 7.3 Section 7 CORRECTING MISTAKES If you have finished reading the final DOs and notice mistakes, you can use the bench sheet to correct the mistakes just as you did with the initials. The bench sheet allows you to correct the Final DO providing that the incubation period is between 4 and 7 days. You can also retake all the readings or one bottle. Select Read / Retake Finals and choose either All bottles or This bottle from the menu.
SECTION 8 REPORTS Under the File menu, you will find the Print Daily Bench Sheet and Print Everything Report options. The Print Daily Bench Sheet will print your bench sheet data for the batch you have selected. The Print Everything Report will print all data for the selected batch. To open a sample report, select Open from the File menu. Open the Data folder, and highlight the Sample. mdb file and choose OK. In the Trending menu, choose Report, and then select Design.
Reports 8.1 Section 8 REPORT DESIGN The report designer is used to setup spreadsheet type reports. Daily values and monthly summary values from BOD Analyst software samples can be placed into the spreadsheet. After placement, normal spreadsheet formulas can be used to calculate sums, averages, etc. of the placed BOD Analyst software data. Formatting of the report is done through familiar spreadsheet functions to change fonts, borders and cell colors, etc. 8.1.

Reports Section 8 Note: To resize multiple columns at one time, select all the columns by clicking and dragging the mouse on the column headers. With the columns selected, resize one of the selected columns and all the selected columns will be sized the same. The same method can be used to resize multiple rows at one time. 8.1.4 COPYING DATA You can copy data to and from cells using the familiar Clipboard method. Also, you can drag and drop data to copy a selected block of cells.
Reports Section 8 3. Release the left mouse button when the pointer is over the new location for the copied cells. To move only data: 1. Select the cells you want to move with the mouse. 2. Press CTRL-X (or select Edit/Cut from the menu) to cut data to the clipboard. 3. Click on the destination cell and press CTRL-V (or select Edit/Paste) to paste data from the clipboard. 8.1.6 USING FORMULAS You can define formulas (math expressions) for cells.
Reports Section 8 ABS(A1) The absolute value of the cell is returned. ISEMPTY(A1)If A1 is empty then a 1 is returned. If A1 is not empty then a zero is returned. MAX(A1:A31) Returns the maximum value for the cell range. MIN(A1:A31) Returns the minimum value for the cell range NEG(A1) Changes the sign of the value. For example, NEG (-15) = 15. NOT(A1) If A1 is zero then a 1 is returned. If A1 is not zero then a zero is returned.
Reports Section 8 Offset The offset from the start date of the report. For example, if the start date is 1/1/99 and the offset is 1, the value from 1/1/99 will be returned. If the offset is 2, the value from 1/2/99 will be returned and so forth. Future OPTIONAL, Not Used. VARWO(VarNum, Offset, future, future, future, future, future) Returns the daily value for a sample when data is found. See Print Data only when it occurs example in Locating Data on the Report later in this section.
Reports Section 8 8.1.9 MONTHLY FUNCTIONS Monthly functions return summary values for a sample for a specified month. The VarNum parameter sets the sample to be used. The Offset sets the month to be retrieved relative to the specified report start date. For example, with a report start date of 1/1/99, in Offset of 1 would define January, 2 February, etc.. The easy way to place these functions is to use Locate/Monthly Summary. MSUM(VarNum, Offset) Return the Monthly total for the sample.
Reports Section 8 The ‘<<< Blank Report >>> selection loads a completely blank file. The other selections load a spreadsheet file to start your new document with. For example, choosing Custbill.ss2 will load a file with all the text, borders, and statistics setup for creating a bill for a customer. Use Locate, Sample to place your data in the report and the report is complete. To add a template to the list, simply copy the “SS2" file from your data directory to the BOD Analyst software directory.
Reports 8.2 Section 8 EDIT MENU FUNCTIONS To cut numbers, data values or text within the currently selected cells to the clipboard, use Cut from the Edit menu. Formulas and format settings will NOT be cut. Data values that have been cut from cells containing formulas will reappear the next time the spreadsheet calculates itself. In order to remove formulas along with their resulting values or to reset cell formatting, use Clear on the Edit menu instead of Cut.
Reports Section 8 The Locate Sample Formula dialog can also be opened by clicking on the Locate Sample button, . The fields on the Locate Sample Formula form are as follows: Sample: Select the sample to locate. Decimal Places: The number of digits to show behind the decimal point. Print Data only when it occurs: Skips days with no data. The example below illustrates how to use this field. Place Date beside data: Places the corresponding date in the column next to the located data.
Reports Section 8 Sample Name: Check the sample name box to have the sample name appear as a column heading. Units: Check the units name box to display the units as a column heading.

Week Definition: Select the way weeks are to be divided. 8.3.3 LOCATING MONTHLY SUMMARY DATA VALUES Locate, Monthly Summary is used to place one or a series of monthly summary statistics on the spreadsheet. It builds a formula that the spreadsheet uses during calculations to retrieve data from the BOD Analyst software database. Values are placed starting at the current cell.
Reports Section 8 Statistic: Sets the summary statistic to use. Decimal Places: The number of digits to show behind the decimal point. 8.3.4 LOCATING DATES ON THE REPORT As well as placing dates along side data values while using Locate, Sample, formulas for dates can be located on the report using the Locate, Date feature. This feature offers a wider range of formatting choices in that the dates can be placed weekly and monthly as well as daily.
Reports 8.4 Section 8 FORMATTING CELLS The BOD Analyst software Report Designer offers great flexibility in formatting cells. All formatting is accomplished using the items on the Format menu. This menu also provides for the insertion of page breaks. Format, Font opens the font dialog with which font settings can be changed for the current cell or an entire block of cells. Settings for font color are ignored here. The background color and foreground color (font color) are set using Format, Cell Colors.
Reports 8.5 Section 8 OBTAINING HELP WHILE DESIGNING REPORTS The help menu provides access to context sensitive help while designing a report. The help system can also be activated by simply pressing the F1 function key. 8.6 PRINTING REPORTS Trend reports may be printed without entering the report design mode by selecting Report, Print from the Trending menu. This functionality allows the user to select multiple reports to be printed in a batch print job.
SECTION 9 KEEPING YOUR DATA SAFE 9.1 DATE The BOD Analyst software depends on the correct date to do its calculations and manage the data. The current date on your computer is displayed in the upper right hand corner of BOD Analyst software. If the date is incorrect, exit BOD Analyst software and correct the date in windows (click on the Date/Time icon in the Control Panel). 9.2 HARDCOPIES No computer is perfect, and once in a great while, a failure will cause data to be lost.
Keeping Your Data Safe Section 9 will be created and opened. You must setup your samples and groups just as you did with the default database. To open an existing database select File, Open and select the database. Click OK and the database will be opened. BOD Analyst software data files can be located anywhere (i.e. the local drive, network drive). In a network environment, two workstations CAN have the same data file open.
SECTION 10 GRAPHING 10.1 INTRODUCTION The graphing function provides the ability to produce time series type (Data vs. Time) graphs. Up to two samples may be displayed at the same time, each on its Y-axis. To open a sample graph, select Open from the File menu. Open the Data folder, and highlight the Sample. mdb file and choose OK. In the Trending menu, select Graph. To display the sample graph, change the Start date to 01/01/99 and the End date to 01/30/99.
Graphing Section 10 Sample 1 and Sample 2 are the fields in which the sample names are selected. If one sample name is selected the left y-axis will be used. If two samples are selected, both axis will be used, Sample1 on the left and Sample 2 on the right. The data line and the axis label are color coordinated when in color mode. When black and white printing mode is selected, the second sample (using the right axis) will use a dashed line and a series of dashes are added to the right axis title.
Graphing Section 10 differences between printing in color or black and white. 10.4 GETTING STATISTICAL INFORMATION ABOUT SAMPLES After creating a graph as described above, click on the STATS button to display the Stat Sheet. This tabbed dialog displays statistical information for each of the variables on the graph. To display a statistic, click on the corresponding Plot check box.
SECTION 11 CUSTOMIZING YOUR PROGRAM The BOD Analyst software is flexible enough to handle the wide variety of ways that people do their BODs. Some things are very simple and are little more than matters of personal preference. This section outlines the advanced settings that can be used and specified in the YSI BOD Analyst for Windows. For others, flexibility is essential because what works well in one application will give poor results in another.
Customizing Your Program Section 11 number. The auto-stable routine starts immediately after the bottle number is entered. You can choose exactly how and when a stable reading will be stored; we refer to this as the auto-stabilization technique. The fastest way is to store the reading as soon as your stability criteria are met. Entering the bottle number (by any method) is an implied confirmation that you are ready for the reading to be stored as soon as it is stable.
Customizing Your Program Section 11 Maximum acceptable value for Initial DO minus Final DO in the dilution-blank test. This criterion is checked only for Dilution Blank samples. The default value is 0.2 mg/l. Maximum Initial Dissolved Oxygen (mg/l) The maximum acceptable value for the Initial DO. This is checked for all tests. The default value is 9.7 mg/l. Minimum Final Dissolved Oxygen (mg/l) The minimum acceptable value for the Final DO This is checked for all tests. The default value is 1.0 mg/l.
Customizing Your Program Section 11 The maximum acceptable value of BOD for tests with the sample name Standard. The default value is 237 mg/l (or, 200 plus 37). Check Coefficient of Variation Calculates a Coefficient of Variation (CV) for all dilutions in a sample and checks that value against the CV limit. If the CV limit is exceeded, the lowest concentration dilution is removed from the average and the CV is calculated for the remaining dilutions and the CV is checked again.
Customizing Your Program Section 11 want the program to derive. You must measure at least one dilution for each Sample. It is best to measure the strongest dilution. If you measure more than one dilution for a Sample, the program will use a weighted average of the measured dilutions to derive the others. The default value is unchecked (off). Blank compensation: You may compensate your BODs for the depletion of your blanks by checking this field. This is common in the United Kingdom.
Customizing Your Program Section 11 Technique: This field describes exactly how and when a stable reading will be stored. There are four legal values, Auto, Dual, Manual, and None. Auto will start the auto-stable routine immediately after the bottle number is entered and will store the reading as soon as your stability criteria are met. This is the fastest way. Dual is similar.
Customizing Your Program Section 11 Initial low temp: If the temperature of your initial DO is below this temperature (in °C) the program will display a warning message at the YSI 5000/5100 DO Instrument before the reading is stored. Legal values are 0 through 99.9. The default value is 16. Initial high temp: If the temperature of your initial DO is above the temperature (in °C) the program will display a warning message at the YSI 5000/5100 DO Instrument before the reading is stored.
Customizing Your Program Section 11 Comm port: The program can communicate to the YSI 5000/5100 DO Instrument through either communications port 1,2,3, or 4. In this field, indicate the communications port you will use to connect to the YSI 5000/5100 DO Instrument. On newer computers, com1: is typically used. If the program is unable to initialize communications with the YSI 5000/5100 DO Instrument, then come back to this form and try a different port.
Customizing Your Program Section 11 Use Serial Number: Sets whether the program will assign Serial Numbers. The default is off. Serialize Each: The program can assign a new serial number to each bottle or each sample. The default is Sample. YSI Displays: The YSI can display the Sample name or serial number when taking readings. The default is Sample Name. Lowest Digits: Used in conjunction with the Highest Digits field to specify how the software will increment the serial number.
