2. Equipment Needed
TI Graphing Calculator (82, 73, 83, 83+, 84, 84+, 92, 92+)
Calculator Based Ranger (CBR)
Calculator-to-Calculator Cable

3. Conic Distribution of Sound “Clicks”
Remember that the cone is three-dimensional

4. Buttons we will be using:
Enter
“Apps”
Arrows
2nd

5. Set-up
Plug one end of the cable into the bottom of the TI Graphing Calculator
Plug the other end of the cable into the Calculator Based Ranger (CBR)
As shown in the two images

6. Real-life Set-up

7. Steps Part 1: Turn on the Calculator
Click the “Apps” button And you will see a screen similar to the one shown
Choose “CBL/CBR” and press “Enter”
Follow the screen Direction (Press Any Key) Till you reach the following screen and then choose “3:Ranger”

8. Steps Part 2:
You’ll see this screen next and then you should press the “Enter” key
Then you’ll see the following screen. Choose “1:Setup/Sample” and press “Enter”
To arrive at the following set of options

9. Steps Part 3:
Change options to read as shown. Scroll through options and press “Enter” to change options.
Scroll up to “Start Now” and press “Enter” to arrive at one of the following screens. The second is an error – make sure your cables are properly plugged in.
Once the CBR and TI are “speaking” with one another and you click “Enter” you will hear a series of clicks.

10. Starting Out Using the Distance Sensor
Now that we know how to set up the equipment let’s start using it
Point the distance sensor at an object and the user moves the sensor, or
The user or another object (like a ball) is moved or moves in front of the distance sensor

11. User Points at an Object and moves with the Distance Sensor
An effective way for a single student to conduct experiments and create and explore graphs
The idea is that the “user” operates their own devices and creates their own graphs through their movements with the distance sensor and a stationary object
Image from:

12. User or Object Moves in Front of Distance Sensor
The “mover” or an object (like a ball) moves in front of the distance sensor while someone else operates the “collect” button.
Images from:

13. Graphs to match Parabolic Peak Constant Horizontal Loopy Times
Stair Step
Plateau
Wave-Try to make a different wave too
Vertical
Butte

14. My attempt at the wave graph
As you can see my attempt is not the same as the intended graph. It’s close but fortunately…
I can try again by pressing “Enter” after my graph choosing “3: Repeat Sample”

15. Create your own graph and draw it
Create your own graph and draw it in the screen shown and explain the procedure to create it below:
_________________

16. Graph Analysis Determine High and Low Points
Determine Slope over an interval by calculating the Change in Y over the Change in X for points chosen

17. The Gauge Option
From the Main Menu choose “1:Gauge” Hint: may have to move through the “apps” menu sequence again.
You will then be prompted with some options
The Bar option is shown
The Meter option is shown

18. The Data Logger Option There is another way to create graphs
From the Main Menu choose “2:Data Logger” Hint: may have to move through the “apps” menu sequence again.
You will then be prompted with some options
The most important are “Samples” and “Intrvl(sec)” and “RealTme”
