The CBL 2 is packaged so it can be used right out of the box with a minimal amount of set-up time. To familiarize yourself with all the features found on the CBL 2, Texas Instruments provides an "Introduction to CBL 2" which explains what makes the CBL 2 unique.

The CBL 2 system can be easily connected to become a single, hand held unit which is both portable and compact.

Out of the Box: A QuickTime Streaming Video will take you step by step through the process of using the CBL 2 for the first time.

The steps shown in the movie parallel the written instructions below.

In addition to "Out of the Box," the links below provide step by step instructions for each of the listed processes:

Retrieving a Saved Experiment

Changing the Auto-ID Sensor

Out of the Box

The following steps will take you through the set-up and the use of the CBL 2 with the TI-83 Plus calculator to conduct a simple
temperature data collection.

1. Open the back cover of the CBL 2 unit and insert the batteries.

2. Slide the CBL 2 into the the back of the cradle until it locks into place. Insert the calculator into the cradle on top of the CBL 2 unit and click into place.

3. Place one end of the six inch unit to unit link cable into the port on the bottom of the calculator and the other end into the CBL 2 unit.

4. Plug the other end of the link cable into the port on the bottom of the CBL 2 unit

5. Turn the calculator on.

6. Reset the memory on your calculator by pressing "2nd" then "MEM" which is the + key. Then choose "RESET" which is 7 by scrolling down or clicking the 7 key.

7. Choose 1,"All RAM" then 2, "RESET" on the next screen. A warning will be displayed that says, "Resetting RAM erases all data and programs from RAM."

8. A screen will be displayed that says "RAM cleared." Press "ENTER" and the word "DONE" will appear on the screen.

9. Put the calculator in receive mode by pressing "2nd" then "LINK." Arrow over so that "RECEIVE" is highlighted then press "ENTER."

10. The calculator will display a "Waiting" screen. Press the "TRANSFER" button on the CBL 2 unit. The CBL 2 unit detects which calculator is connected and sends the appropriate version of the DataMate software to the calculator.

11. The calculator will display a "Receiving" screen. When the calculator has received the program, "Done" will be displayed on the screen.

12. Plug the temperature probe into "~CH 1" on the left hand side of the CBL 2 unit. Remember that the probes should be plugged into the channel ports in the appropriate order using channel 1 first, channel 2 second and channel 3 last. If you are only using one probe, use channel 1 only.

13. To run the DataMate program, click the "APPS" button on the calculator and then arrow up or down to highlight the DataMate program. Press "ENTER."

14. A screen is displayed which says, "CHECKING SENSORS." If the calculator has identified the temperature sensor correctly, a screen will be displayed that says, "CH 1: TEMP (C) and the current reading as determined by the temperature sensor.

15. DataMate automatically loads a default temperature experiment and the main screen is displayed.

16. Start collecting data by placing the temperature sensor in your hand and pressing 2 which is "START." A real-time graph of the temperature will be displayed.

17. After approximately one minute, click on the "STO›" key. Your graph will be displayed on the screen.

18. Use the arrow keys to move through each data point on the graph. The graph can be saved for retrieval at a later time.

Saving an Experiment

1. From the graph window, press "ENTER" to return to the main screen.

2. From the main screen menu, select 1 which is "SETUP."

3. Choose 4 which is "SAVE/LOAD."

4. Choose 1 which is "SAVE THE EXPERIMENT."

Note: From this window you can also choose 2 which is "LOAD EXPERIMENT," 3 which is "DELETE EXPERIMENT" or 4 which is "DELETE ALL EXPERIMENTS."

5. You will then be prompted to "ENTER NAME" after choosing 1 which is "SAVE THE EXPERIMENT."

6. Choose "2nd" then "ALPHA" to use the letters which are above the keys to type in a name for your experiment. The name can be up to 20 characters in length with a combination of both letters and numbers.

7. Press "ENTER" and a "SAVING...." message will appear. Once the experiment is saved, you will be returned to the "EXPERIMENT MENU." Press 5 to return to the "SETUP MENU" and then 1 to return to the main screen.

Retrieving a Saved Experiment

1. On the main screen menu, select 1 which is "SETUP."

2. Choose 4 which is "SAVE/LOAD."

3. Choose 2 which is "LOAD EXPERIMENT."

4. Select an experiment to load. Click on the number which corresponds with the name of the experiment you want to load and press "ENTER." A "LOADING....." message is displayed.

5. Once the experiment is loaded, you will be returned to the main screen.

6. To retrieve the graph, choose 5 which is "TOOLS" and then 2 which is "RETRIEVE DATA."

7. The graph will be displayed.

Changing the Auto-ID Sensor

1. Remove the temperature sensor from "~CH 1"and plug in the light sensor.

2. Once again, the CBL 2 checks the sensors and automatically identifies the sensor.

21. Start collecting data by moving the light sensor towards or away from a light source.

22. A message will be displayed on the screen which says, "SAMPLING."

23. When the sampling interval ends, your graph will be displayed on the screen.

24. Use the arrow keys to move through each data point on the graph. The graph can be saved for retrieval at a later time.
