2Equipment Needed
- TI Graphing Calculator (82, 73, 83, 83, 84, 84,
92, 92) - Calculator Based Ranger (CBR)
- Calculator-to-Calculator Cable
3Conic Distribution of Sound Clicks
- Remember that the cone is three-dimensional
4Buttons we will be using
5Set-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
6Real-life Set-up
7Steps Part 1
- Turn on the Calculator
- Click the Apps buttonAnd you will see a screen
similarto the one shown - Choose CBL/CBR and press Enter
- Follow the screenDirection (Press Any Key)Till
you reach the following screen and then
choose3Ranger
8Steps Part 2
- Youll see this screen next and then you should
press the Enter key - Then youll see the following screen. Choose
1Setup/Sample and press Enter - To arrive at the following set of options
9Steps Part 3
- Change options to read as shown. Scroll through
options and press Enter to change options. - Scroll up to Start Nowand 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.
10Starting Out Using the Distance Sensor
- Now that we know how to set up the equipment
lets 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
11User 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

12User 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.

13Graphs to match
Parabolic Peak
Constant
Horizontal
Loopy Times
Stair Step

Wave-Try to make a different wave too
Vertical
Butte
14My attempt at the wave graph
- As you can see my attempt is not the same as the
intended graph. Its close but fortunately - I can try again by pressing Enter after my
graph choosing 3 Repeat Sample
15Create your own graph and draw it
- Create your owngraph and draw it in the screen
shown and explain the procedure to create it

16Graph 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
17The Gauge Option
- From the Main Menu choose 1Gauge 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
18The Data Logger Option
- There is another way to create graphs
- From the Main Menu choose 2Data 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
