Overview CBL Made Easy! This CBL guidebook is a step-by-step guide to collecting data using the original Calculator-Based Laboratory (CBL) and a Texas Instruments graphing calculator. It was written in a sequence to be followed from the purchase of necessary materials, through the setup and data collection procedures, and on to areas of further interest.
Getting Started Required Materials To load Vernier supplemental programs onto your TI handheld, you will need: • • • • A Texas Instruments handheld TI-GRAPH LINK cable TI Connect or TI-GRAPH LINK software Vernier CBL programs Supported Handhelds The CBL supports several Texas Instruments handhelds. Program loading instructions are available in Step 2 of this manual.
Step 1: Load Programs onto Your Computer Now load the TI Connect or TI-GRAPH LINK software and CBL programs onto your computer. Important: You will need TI Connect unless you are a Windows user and you are using either the TI-82, TI-85, or TI-86 handhelds. If that’s the case, you will need the TI-GRAPH LINK software for Windows.
Step 1 Load Programs onto Your Computer • A file ending with a “g” (chembio.83g, for example) is a group program. All calculator types (except for the TI-83 Plus and the TI-83 Plus Silver Edition) run group programs when using the CBL. • A file ending with “8xk” (chembio.8xk, for example) is an application for use with the TI-83 Plus and TI-83 Plus Silver Edition. Sources for CBL Programs: • Vernier web site (www.vernier.com).
Step 2: Load Programs onto Your Calculator Using TI Connect TI Connect for Windows and Macintosh is very easy to use. It works with all TI handhelds, unless you are using a TI-82, TI-85, or TI-86 and a Windows computer. In that case, TI-GRAPH LINK must be used. The TI-83 Plus and TI-83 Plus Silver Edition needs to be running operating system version 1.152 or newer to work with TI Connect. Windows Computers 1.
Step 2 Load the Program onto Your Calculator Macintosh Computers 1. Connect the TI-GRAPH LINK cable to the serial or USB port of your computer and to the port at the bottom edge of the TI-82, TI-73 Explorer, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-85, TI-86, TI-89, or the top edge of the TI-92, TI-92 Plus, or Voyage 200 handheld. 2. Turn on the handheld and start the TI Connect software on your computer. (The TI-82 and TI-85 must be put in Receive mode.
Load the Program onto Your Calculator Step 2 5. Click on Add. The file name is copied to the bottom window of the screen. 6. Click on OK. The sending window appears. When the file transfer is complete, click on OK. The group of programs is now loaded into your calculator. 7. You can confirm that the program has been loaded by pressing the PRGM key on the calculator. TI-83 Plus Calculators 1.
Step 2 Load the Program onto Your Calculator 4. Open the folder that contains your CBL programs (for example, “TI-82”) then open the appropriate file (for example, “chem-bio.82g” or “physics.82g”). The “g” in the name denotes a group file. NOTE: When you are selecting the group file, do not double-click it. 5. Click on Send. The group of programs is now loaded onto your calculator. 6. You can confirm that the program has been loaded by pressing the PRGM key on the calculator. TI-85 Calculators 1.
Load the Program onto Your Calculator Step 2 TI-GRAPH LINK Troubleshooting Problem Solution My TI-GRAPH LINK for Macintosh program does not see the group file in the CBL program folder. Within the older TI-GRAPH LINK for Macintosh software, you have “All Objects” selected from the pull-down menu at the bottom of the screen that comes up when you try to link. You need to have “Group” selected from that list of choices.

Step 3: Putting it All Together Now you are ready to get your hardware set up. This is the easy part. At the base of the CBL are two ports. The left port is the communications port. This connects the CBL to the calculator via the black calculator link cable. Be sure to push the cables firmly in when connecting the two components.3 There are four jacks located along the top and the left of the CBL unit in which you can plug Vernier or TI probes. They are labeled CH1, CH2, CH3, and Sonic.

Step 4: Collect Data - A Temperature Experiment Now you are ready for the fun part—collecting data! Here is a simple temperature experiment to try.4 It will guide you through the process of making measurements using a temperature probe and the CBL system. Once you are familiar with the basic steps, you will be able to perform any experiment with the CBL.
Step 4 Collect Data 4. Turn on the CBL unit and the calculator. Follow these steps to start the CHEMBIO, PHYSICS, or PHYSCI program on your calculator: TI-73, 82 or 83 Calculators: Press PRGM , then press the calculator key for the number that precedes CHEMBIO, PHYSICS, or PHYSCI program (usually 1 ). Press ENTER , then press ENTER again to go to the MAIN MENU. TI-83 Plus Calculators Press APPS , then press the calculator key for the number that precedes CHEMBIO, PHYSICS, or PHYSCI program.
Collect Data Step 4 9. When exactly 20 seconds have gone by (when the fifth data point appears on the calculator screen), quickly move the temperature probe to the beaker containing hot water and continue data collection. Do not stir the water or move the temperature probe during the remainder of the data collection period. 10. When data collection is complete, press ENTER to display a graph of temperature vs. time on the to examine the data points along the curve. calculator screen. Use 11.

Step 5: Sending Graphs and Data to Your Computer (optional) Now that you have collected data, you can, of course, analyze data with your calculator. However, if you wish to analyze the data on a computer or print the data, you will need to use the TI-GRAPH LINK cable to transfer the data back to your computer. Graphical Analysis and Logger Pro 3 programs are not required for data collection with the CBL.
Step 5 Sending Graphs and Data to the Computer TI-82: On the TI calculator, press 2nd [LINK], then select 2:SelectAll-... from the SEND menu. Use to locate the lists on the SELECT menu. Position the arrow in front of a list you want to send to Logger Pro and press ENTER to select it. More than one list may be selected in this manner. A black square will appear beside each list that will be sent. To deselect, press ENTER . The black square will disappear. Press , then select 1:Transmit.
