Whats New?

In the past, each activity in CBL System Experiment Workbook used one or more TI Basic programs. These files were stand-alone files with.83p file extensions. When performing an activity, you would download all the files you needed into your calculator from the PC using the TI-GRAPH LINK program. To use the programs, you would make a selection from the calculator EXEC menu. In order to use the programs, all the programs had to be in memory at the same time. The same TI Basic programs have now been modified to work with the TI-83 Plus. Similar stand-alone TI Basic files are still available, but these now have.8xp extensions. The functions that the programs perform are essentially unchanged from the TI-83, but cosmetic changes have been made where necessary. In addition, for the TI-83 Plus we have provided versions of these programs in the form of an application. Application files have.app file extensions on the PC. You can download applications to the calculator using TI-GRAPH LINK or the Flash Installer provided by TI. (The Flash Installer currently is not available for the Macintosh, so Macintosh users will need to install the standalone programs using TI-GRAPH LINK.) When you load an application into the calculator, it is put in the Flash ROM, so it does not take up space in RAM. To use an application, press 9 and select the application name from the APPLICATIONS menu.
How to Install the Application Using the Flash Installer
The Flash Installer is currently available only for the Microsoft Windows platforms (Windows 3.1, Windows 95, and Windows NT). 1. Close all desktop applications that may have been started after you downloaded the flash software. (Another running application could interfere while the flash software is updating your TI-83 Plus.) Make sure the TI-GRAPH LINK cable is firmly connected to the calculator and the computer.
3. Start the flash software installation by double-clicking on the flash software file (cblmath1.exe, for example) on your computer and following the instructions. The TI-83 Plus may briefly display a "Defragmenting" message. This simply means the calculator is preparing for downloading. While the application is downloading, the TI-83 Plus will display the message Receiving *CBLExpmt app.
1999 Texas Instruments Incorporated
When the installation is complete, the Flash Installer screen will display a message that the installation was successful. The calculator will remain on. Important: DO NOT interrupt the installation process. If you encounter any errors during the installation, follow the instructions. Error Recovery instructions are also described below. CBL System Experiment Workbook activities are grouped into one application entitled CBLExpmt.app.
How to Install the Application Using TI-GRAPH LINK
1. 2. 3. 4. 5. 6. Connect the TI-83 Plus and your computer with the TI-GRAPH LINK cable. Turn on the TI-83 Plus and leave it at the Home screen. Start the TI-GRAPH LINK software. Click on the Link menu, then click on Send. Select the directory into which you downloaded the application files, and then select the file you want to load on the TI-83 Plus. Click OK to transmit the file.
How to Start the Application
To use an application, press 9 and select the application name from the APPLICATIONS menu. To remove the title screen, press. To exit the application at any time, press 2 K.

How to Run the Programs

When you start any application, after you press to remove the title screen, you will see a main menu listing the names of the original TI Basic programs available in that application. These names correspond to the names given in CBL System Experiment Workbook. In order to run a program mentioned in the activity book, you must run the application, and then select the program name. To run the program: Press the number in front of the program name or Use to highlight the program name and press. To move around the main menu: Use } and to move one line at a time. or } or to move one screen at a time.

You can quit the application from the main menu by pressing y K or by selecting the QUIT option listed on the menu. Once you select a program from the menu, that program begins running. The programs run nearly identically to the way they did on the TI-83. When you quit a program by selecting a QUIT option or the program ends normally on its own, you return to the application main menu, where you may select a new program to run or exit the application. (To exit, press or 2 K.)

Error Messages

ERR:BREAK If you press while a program is running, you will see a screen with the message ERR:BREAK. This means that you have not only quit the program currently executing, but also exited the entire application and returned to the Home screen. ERR: MEMORY The calculator can store up to ten pages of applications. These pages can be divided among different applications. Data in the calculator Archive reduces the number of pages available to applications. In order to run a selected program, the application must load the program into RAM, so there must be enough free RAM available. If there is not enough RAM to run the selected program, the application will exit and you will see a screen with the message ERR: MEMORY. You should make more RAM available by deleting or archiving items currently in RAM, and then run the application again. If the application exits normally, or because of a break or out-of-memory error, it automatically removes the TI Basic programs that it loaded into RAM. Other errors Other types of errors may occur while you are running a program. If any other type of error occurs, the application will exit and you will see a screen beginning with ERR:, followed by the type of error. Such an error often indicates that the activity was not performed in the proper sequence as described by the activity, or that data collected from the CBL was in error. When such an error occurs, the TI Basic program(s) that the application loaded into RAM are not removed automatically. Since they remain in RAM, the error screen provides a GOTO option. If you select the GOTO option, the calculator will show which line caused the error. This may help in diagnosing the problem. ERR:DUPLICATE NAME Before the CBL application runs a selected program, it first checks to see whether a program with that name already exists in the calculator. If a program with the same name already exists and is archived, the application will display an error message and exit. The application cannot create another program with the same name in RAM as one in the archive. You must either delete the existing archived program, rename it, or unarchive it into RAM to be used in place of the built-in application version. If a program with the same name already exists and is protected, the application will display an error message and exit. The application will not replace a protected program with its own version. You must either delete the existing protected program or rename it. If a program with the same name already exists in RAM and is not protected or archived, the application will display a menu of options for you to select from. Option 1:USE IT means that the application will not replace the existing program with its own version, but will instead use the existing version. This may be useful if you encounter an error during a previous program run and alter the program to try to fix the error. You can also modify the original TI Basic program file and load it into your calculator and it will be used in place of the built-in application version. If you select this option, the application will never automatically remove the program. Option 2: REPLACE IT means that the application will replace the existing program in RAM with its own version. If the application later exits normally, it will also automatically remove its own version from RAM so that nothing remains. Option 3: REPLACE ALL is the same as Option 2, except that the application will automatically replace any other programs that it uses (in those cases where it uses more than one) if duplicates exist in RAM. This simply keeps the application from presenting the menu to you multiple times. Option 4: EXIT THIS APP exits the application without changing RAM in any way. You may want to select this option in order to explore what is in the existing program.

How the application differs from the previous stand-alone programs
There is one noticeable difference between the stand-alone versions of the activity programs and the versions built into the application. Many of the stand-alone programs display a graph and quit. The user can view the graph and then sometimes go into TRACE mode to move along the graphed function. In the application, when the graph is drawn you are automatically put into Trace mode. After tracing, you should press the key to continue running the program. This change was necessary so that you would not have to repeatedly re-start the application. Some of the descriptions in the activity book are written assuming the behavior is that of the stand-alone program. Whenever the activity requires tracing, you should wait until the application automatically puts you in TRACE mode to do that part of the activity. If you need to TRACE later, you can do this by exiting the application, pressing s to display the last graph, and pressing r to enter TRACE mode, which will still be functional.
How to Delete an Application
If an error message indicates that you do not have sufficient space on the TI-83 Plus, you will need to delete one of the current applications. To do this: 1. Press - to display the MEMORY menu. 2. 3. 4. 5. 6. Select 2: Mem Mgmt/Del. Select A: Apps. Press # to place the 4 symbol at the left of the application you wish to delete. Press / to delete the application. A screen displays Are You Sure? Select 2: Yes.

Collecting Data Out of the Box Using the CBL 2 System
1. 2. Insert batteries into the CBL 2. Connect CBL 2 to a TI graphing calculator using the unit-to-unit link cable. (Use the cradle if desired; see diagram on the cradle or the instructions on page 4.) If you are using the TI-83 Plus or TI-83 Plus Silver Edition, proceed to step 4. If you are using the TI-89, TI-92 Plus, or Voyage 200 PLT (personal learning tool) proceed to step 5. 3. Reset the memory of your calculator. Reset is necessary only for the TI-73, TI-82, and TI-83. To reset RAM, press y L, choose 7:Reset, then choose 1:All RAM, and then choose 2:Reset. This is a required step due to the size of the DataMate programs that are stored in RAM. 4. Put calculator in Receive Mode (waiting to receive information):
For TI-73, press 9, choose Y LINK, press " to RECEIVE, and then press b. For the TI-82, TI-83, TI-83 Plus, and TI-83 Plus Silver Edition, press y 8, press ~ to RECEIVE, then press.
Press the TRANSFER button on the CBL 2. The CBL 2 detects the calculator to which it is connected and sends the appropriate version of the built-in DataMate software. (This software controls the CBL 2 and how it collects data.) Plug your Stainless Steel Temperature sensor into Channel 1 (CH1) of the CBL 2. Run DataMate:
For TI-83 Plus and TI-83 Plus Silver Edition, press 9. Press or } to highlight DATAMATE and press. For the TI-73, TI-82, and TI-83, press. Press DATAMATE or press. DATAMATE is pasted to your home screen; press again to confirm your choice. For the TI-89, TI-92 Plus, and Voyage 200 PLT, if the Apps desktop is turned on, press O, highlight DataMate, and press. or If the Apps desktop is turned off, press O, highlight DataMate, and press.
DataMate automatically identifies the Stainless Steel Temperature sensor, loads its calibration factors, and displays the name of the sensor, as well as the temperature in degrees C. It also loads a default temperature experiment. Start collecting data with the default experiment. Hold the temperature sensor in your hand and press START to begin data collection.

Software

The CBL 2 comes with DataMate already loaded. DataMate is a multi-purpose user program containing the basic information needed to run experiments with a CBL 2, a TI graphing calculator, and various sensors. DataMate is provided for the following TI graphing calculators: TI-73, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-86, TI-89, TI-92, TI-92 Plus, and Voyage 200 PLT. For the TI-83 Plus, TI-83 Plus Silver Edition, TI-89, TI-92 Plus, and Voyage 200 PLT, DataMate is a calculator software application that is run from the APPS menu; for the other calculators, it is a program that is run from the calculators program menu. The CBL 2 automatically detects which calculator is attached and sends the appropriate software. Because of the differences in memory between the calculators, there are some differences in functionality between by the different versions of DataMate.
The TI-83 Plus, TI-83 Plus Silver Edition, TI-86, TI-89, TI-92, TI-92 Plus, and Voyage 200 PLT versions support all of the DataMate functions. The TI-83 version of DataMate supports all of the functions except SAVE/LOAD. The TI-73 version of DataMate supports all of the functions except SAVE/LOAD and ADD MODEL.
The TI-82 version of DataMate supports only auto-ID sensors: temperature, light, voltage, and the CBR device or the new Vernier Software and Technology (Vernier) motion detector. It supports all of the functions except SAVE/LOAD, SELECT REGION, ADD MODEL, and ANALYSIS.
See page 5 for instructions on using the DataMate software.

Sensors

Three sensors are provided with the CBL 2 (stainless steel temperature, TI light, and TI voltage), and many other available sensors can be used with CBL 2, including the CBR and the following Vernier sensors: CBL Motion Detector CBL Microphone Digital Control Unit Dual-Range Force Sensor Student Force Sensor Flow Rate Sensor Magnetic Field Sensor Turbidity Low-g Accelerometer 25-g Accelerometer 3-Axis Accelerometer Extra Long Temperature Sensor Current/Voltage Sensor System Vernier Photogate Direct-Connect Temp Sensor Stainless Steel Temp Sensor Relative Humidity Sensor pH Sensor Pressure Sensor Thermocouple Colorimeter Conductivity Sensor Ion-Selective Electrodes (NO 3 -, CI -, Ca 2+, NH 4 +) Ion-Selective Electrode Amplifier Instrumentation Amplifier Student Radiation Monitor CO 2 Gas Sensor O 2 Gas Sensor Dissolved Oxygen Sensor Biology Gas Pressure Sensor Gas Pressure Sensor Respiration Monitor Belt EKG Sensor Exercise Heart Rate Monitor Heart Rate Monitor Barometer

Note: For updated lists of available sensors, see the web site for Vernier Software and Technology at www.vernier.com.
Sensors are attached to CBL 2 though input or output connections called channels. CBL 2 has three analog channels (CH1, CH2, CH3) and one other channel (DIG/ SONIC) that can be used for ultrasonic motion detector or digital inputs and outputs. When using DataMate, the auto-ID feature on the CBL 2 allows the unit to automatically identify specific sensors when you connect them to the unit. When you connect an auto-ID sensor to a channel, CBL 2 detects the sensor, loads calibration factors and a default experiment, and shows the channel number and sensor type in the calculator display. Auto-ID sensors include the stainless steel temperature, TI voltage, and TI light sensors included with the CBL 2, as well as the CBR and the Vernier motion detector. (Additional Vernier auto-ID sensors are planned.)
2000, 2003 TEXAS INSTRUMENTS INCORPORATED GETTING STARTED WITH THE CBL 2 SYSTEM 3
Sensors that are not auto-ID can also be used with CBL 2 by selecting the sensor type from a list of sensors in DataMate.
Note: Technical specifications of TI sensors (including chemical tolerance) are provided in the CBL 2 Technical Reference document available on the TI web site and the Resource CD.

Getting Started

Before you begin working with the CBL 2 system and the DataMate software, you must connect the CBL 2 and your calculator and transfer the software from CBL 2 to your calculator.

Put the Pieces Together

Figure 2. Connecting CBL 2 to a Calculator
1. Insert the upper end of the calculator into the cradle. 2. Press down on the lower end of the calculator until it snaps in place. 3. Slide the back of the cradle onto the front of the CBL 2 until it clicks in place. 4. Plug one end of the 6-inch unit-to-unit link cable into the I/O port in the end of
the CBL 2, and plug the other end of the cable into the I/O port in the end of the calculator. The cradle cannot be used with the TI-92, TI-92 Plus, or Voyage 200 PLT. Attach these calculators using a unit-to-unit cable.
Transfer DataMate to the Calculator
DataMate comes already loaded on your CBL 2. When transferring DataMate from CBL 2 to the calculator, the CBL 2 automatically detects which calculator is attached and transfers the appropriate version of DataMate.
To transfer DataMate to a TI-83 Plus and TI-83 Plus Silver Edition calculator, follow these steps:
1. Connect the calculator to CBL 2 with the unit-to-unit link cable. 2. Put the calculator in Receive mode. (For the TI-83 Plus and TI-83 Plus Silver

Edition, press y 8 ~.)

3. Push TRANSFER on CBL 2. The program/app is transferred and appears in the
calculators program list or application list.
4. When the transfer is complete, press y 5 on the calculator.
See steps 4 and 5 on page vi for the TI-73, TI-82, TI-83 Plus, and TI-83 Plus Silver Edition instructions.
Note: DataMate on the TI-89, TI-92 Plus, and Voyage 200 PLT is transferred in three segments/files, but only one will display in the App menu. All three segments are necessary for DataMate to run on these units.
Getting Started with DataMate
This section of the User Guide explains the procedures for using DataMate. The instructions were written with the DataMate app for TI-83 Plus and show TI-83 Plus screen examples. (See page 2 for information about the differences between DataMate programs/apps for the various TI graphing calculators.) The basic steps for conducting an experiment with CBL 2, sensor(s), and a TI graphing calculator are:
1. Connect the sensor(s) to the CBL 2 system, connect CBL 2 and your calculator,
and run the DataMate program or App. (See the next section, Start the DataMate App.)
2. Select the data collection mode, if necessary. (CBL 2 contains default experiment
settings for most sensors.) (See page 9.)
3. Collect the data. (See page 12.) 4. Graph the data. (See page 13.)
In addition, DataMate allows you to calibrate some sensors, make changes to graphs, and analyze collected data with pre-programmed options. Procedures for all of these tasks are given on the following pages. It is not necessary to have a calculator connected to the CBL 2 to collect data. The Quick Set-Up feature on the CBL 2 allows you to collect data without having a calculator connected to the CBL 2. You can then transfer the data to your calculator for graphing and analysis. The Quick Set-Up procedure is explained on page 16.
Special Use Calculator Keys
In addition to the keystrokes shown on the DataMate screens, two calculator keys have special uses in DataMate:
Press on the DataMate Main Screen or the Setup screen to restore DataMates default settings. For example, if the sensor setup and/or data collection mode setting are not what you expect, press to reset them. Press while collecting data to stop data collection.

Start the DataMate App

Note: If you are using the TI-73, TI-82 or TI-83, it is recommended that you remove any nonDataMate programs from the calculator before loading DataMate. See step 3 on page vi.
1. Connect the CBL 2 to the calculator. 2. Press.
3. Press h if needed to move the cursor to DATAMATE and press.
The DataMate title screen displays. This screen shows both the DataMate program version number (VER 1.14 in the example) and the operating system version number (ROM: 1.12 in the example). Then the Main Screen appears.

Calibration (option 2 on the Setup screen)
From this screen you calibrate a sensor in either of two ways. The first way is a two-point calibration; the second way is to manually enter slope and intercept values.
Note: Not all sensors can be calibrated. If you select a sensor that cannot be calibrated, DataMate does not display this screen.

Select sensors, data collection mode, calibrate sensors, and manage experiment files. Begin collecting data. Select and view a graph of the data from the experiment. Select the type of analysis you want to perform with the data. Select a tool such as RETRIEVE DATA or CHECK BATTERY. Exit the DataMate program.
DataMate automatically recognizes an auto-ID sensor, identifies the channel to which it is connected, loads a default experiment appropriate to the sensor, and shows the current reading. All active channels are shown, and the Main Screen is updated as auto-ID sensors are added or removed. Sensors that are not auto-ID, such as pressure sensors and pH sensors, must be set up manually. See instructions for Connect a Sensor to the CBL 2 on page 6. The Main Screen defaults to meter mode which updates readings for active sensors every few seconds. To turn meter mode off or on, press on the calculator.

Use five batteries of the same size and voltage. It is best if you use new batteries or a set of batteries that have been used in the same device. The batteries can be held in place using a battery holder, a ruler with a ridge down the center, or even the grout line between tiles on a table or floor. The batteries should be lined up with a positive terminal (+) touching a negative terminal ().

Data Collection

1. Connect the CBL 2 to your calculator using the unit-to-unit cable. Connect the
voltage sensor to the CBL 2 in Channel 1 [CH 1].
2. On the calculator, run the DataMate program or app.
DataMate automatically identifies the voltage sensor and loads a default experiment. The Main Screen of DataMate is shown on the right. (If the MODE setting is different than that shown, press to reset the program.)
3. Place one battery in a battery holder or on a ruler. Touch and hold the
appropriate voltage leads to the appropriate terminal, red to (+) and black to (). You have now created a series circuit with the CBL 2.
4. Read and record the voltage of each of the five batteries on the Student Data
Reporting Sheet, question 1. (Notice that the voltage can be seen on the upper right hand corner of the DataMate Main Screen.)
5. Next, set up the CBL 2 to take a measurement in the
mode EVENTS WITH ENTRY. On the Main Screen, press to select SETUP.
6. Press } or to scroll to MODE and then press.
7. Press for EVENTS WITH ENTRY. This means that you
will record a voltage measure each time you press ENTER.

8. Now, press OK.

9. Press START.
10. Press to take the first measurement of one battery.
When you see ENTER VALUE?, press then press for the first entry. (Each time you press to save a voltage, the calculator asks you to enter a value to keep track of the number of batteries.)
11. Now, line up two batteries in series. Again, touch the red voltage leads to the (+)
terminal and the black voltage leads to the () terminals. Press to collect the voltage of the two batteries. Label this as the second entry.
12. Continue this process until all five measurements have been taken. 13. When you are through taking all of your data, press. You will see the graph

Analysis

1. From DataMate's Main Screen, press GRAPH, and

7. Press to see the scatterplot and the graph of the linear regression. Use |
and ~ to record data points from the linear regression graph. Complete question 3 on the Student Data Reporting Sheet.
8. Press to return to the Analyze screen, then press
to go to the Main Screen. Press QUIT. The events (numbers associated with the order of your data points) you saved are in L1, Celsius temperatures are in L2, and Fahrenheit temperatures are in L3 as shown in the screen shot. You may want to use these for more investigations. Complete questions 4-7 on the Student Data Reporting Sheet.
Use List 4 and the Celsius-to-Fahrenheit conversion formula to create a new list of the conversions. In List 5 find the absolute value of the difference of the measured and calculated Fahrenheit temperatures. In List 6 find the percent of error for each measurement by dividing List 5 by List 4 and multiplying by 100. On the Home screen, find the mean average of these percents. Set up an inverse scatterplot where your x list is List 3 and y list is List 2. Derive the inverse formula for converting from F to C. Find the Celsius temperature when Fahrenheit is 0 degrees. Graph both formulas on the graphing calculator and trace the Celsius line to find the Fahrenheit temperature at.40 degrees Celsius. Other 2-sensor combinations could be used to develop conversion equations dealing with pressure, light, or force.
1. Compare the three graphs of CH1-TEMP (C), CH2-TEMP (F), and CH2 VS CH1
(TEMP (F) VS. TEMP (C)). Sketch the graphs on the axes below. Make sure you label the axes.
2. Write the linear regression equation found using the calculator. This is an
approximate conversion formula to convert Celsius to Fahrenheit. Identify the slope and y-intercept. Round A and B to the nearest tenths. Approximate Conversion Formula: Slope (A) = Y-Intercept (B) =
3. Here is another method to find the conversion formula. Record two different
data points that appear to be on the regression line and that are not very close together. Record the values in the table.

Celsius (X)

X1= X2=

Fahrenheit (Y)

Y1= Y2=
4. Use the points in the table in question 3 to calculate another estimate of the
Slope (A) by using the formula A = (Y2 Y1)/(X2 X1). A=
5. Use the slope in question 4 and one data point from question 3 to derive
another approximate conversion formula. Write this in the form Y= AX + B. Y=
6. It is generally known that 0C equals 32F and 100C equals 212F. Use this
information to derive the exact conversion formula.
X1= X2= A = ______________________ Y = AX + B
Y1= Y2= B = ______________________ Y = ______________________

2. Replace all four AA (LR6) alkaline batteries. Be sure to position them according
to the polarity (+ and N) diagram inside the battery compartment.

3. Replace the cover.

Connecting an Optional AC Adapter
1. Connect one end of an approved adapter to the external power input
connection located on the bottom left side of the CBL 2.
2. Plug the other end of the adapter into an electrical wall outlet.
Approved AC Power Adapters
The CBL 2 is designed to accept voltage input from an external AC-to-DC power adapter that provides a regulated 6 Volts DC output when plugged into an electrical wall outlet. The Texas Instruments model AC-9920 power supply is an AC-to-DC power adapter approved for use with the CBL 2. The model AC-9201 power supply can also be used with the CBL 2. Use of other power adapters may result in RF interference and/or unacceptable performance. To order an adapter, call Customer Support at: 1-800-TI-CARES (1-800-842-2737).
Building an External Battery Adapter Cable
To build an external battery adapter cable, you will need a connector, 16-gauge wire (about 6 feet), and two alligator clips.
Note: At the time of this printing, the Radio Shack Coaxial DC Power Plug #274-1569 (5.5mm O.D., 2.1mm I.D.) or equivalent is an acceptable connector.
1. Identify one 3-foot length of the wire as black (ground) and solder it to the
insulated pin of the connector.
2. Identify the other 3-foot length of wire as red and solder it to the outside of the

connector.

3. Connect an alligator clip to the open end of each wire.

This screen appears when: The CBL 2 has collected data and that data has not been retrieved to the calculator. or The user exits DataMate in the middle of data collection (possibly by pressing ON) and then restarts DataMate. Press ENTER. Then choose one of the following: To retrieve the data, press TOOLS and then RETRIEVE DATA. To delete the data, press CLEAR to reset the CBL 2.
The DataMate main screen shows a non-autoID sensor from a previous experiment even though the sensor is no longer connected. (For example, the screen on the left shows a Relative Humidity sensor even though the sensor was removed and DataMate was restarted.) Press to reset the CBL 2 to initial conditions. (In general, whenever you see something on the screen that does not look correct, press to reset.) This screen appears when the CBL 2 is disconnected from the calculator and used for a different task or when the CBL 2 loses power. When the CBL 2 and calculator are reconnected, the calculator may not recheck the sensor setup, and this error results. Press to reset, and then set up the channel again. These three screens usually appear when there is not enough memory available in the calculator to collect any or all of the data and then graph it. Reduce the number of data points you are trying to collect. Following are estimates of the number of data points that can be collected if the calculator RAM memory has been reset prior to sending DataMate to the calculator:
Calculator TI-73 TI-82 TI-83 TI-83 Plus / TI-83 Plus Silver Edition TI-86 TI-89** TI-92 TI-92 Plus** Voyage 200 PLT** 1 sensor ~120 98* ~200 998* ~~sensors ~90 98* ~150 ~600 ~~998 Sonic ~70 98* ~120 ~400 ~~998
continued from previous page
* This is the limit of the TI-82, TI-83 Plus, and TI-83 Plus Silver Edition calculator list. ** This is the data variable limit for these calculators. You must have Operating System (OS) version 2.05 or higher. The latest OS is available at education.ti.com/softwareupdates.
If using a TI-89, TI-92, TI-92 Plus, or Voyage 200 PLT and a memory error occurs because too many data points were attempted, you must go into the memory management of the calculator and delete the "cbldata" data var. Then restart DataMate and begin data collection. Remember to reduce the number of points collected. This screen usually appears when the user is running DataMate and one of the DataMate subprograms has been deleted from the calculator memory. All of the subprograms must be present in order for DataMate to function properly. (All related programs begin with "DATxxxx.") Reset the RAM on the calculator, then transfer the DataMate program from CBL 2 to the calculator and begin again.

Multiple channels are not allowed to be selected at the same time for the Digital/Sonic inputs. This error usually means that the sonic port and a corresponding digital port have been selected. Command 2 contains invalid data. The filter type must be between 0 and 6 for NON-REALTIME data collection mode and 0, 7, 8, or 9 for REALTIME data collection mode. This error results from a filter selection outside of this range. Command 3 was sent prior to performing any channel setups. Sample time must be greater than 0 and less than 16000 seconds. The value is normally rounded to the nearest 100 sec, but can be rounded to the nearest 50 sec in FASTMODE. If the selected channels cannot support the rate selected, a slower sample rate will be used. The number of samples must be -1 for REALTIME sampling and between 1 and 12,000 for NON-REALTIME sampling. 0 is not allowed except for a special case of REALTIME sampling with manual entry. Trigger type must be an integer between 0 and 6. Any other value will produce this error. The trigger channel must be a valid channel number (e.g., 1-3 or 11) and must be have been enabled using the channel select command. The trigger threshold must be a value between the maximum and minimum legal values for the sensor selected. For example, for the +/-10V probe, legal values are from 10V to +10V. The prestore value must be an integer between 0 and 100%. Any other values will produce this error message. The external clock parameter is limited to values of 0 or 1. Any other value will produce this error. The record time parameter is limited to values between 0 and 2. Any other values will produce this error message. This error will occur when too few parameters are sent in the list. For example, when setting up an equation with 5 constants, if only 4 are sent, this error will result. The equation channel number must be a 0 to reset equation, or a 1-3 for the analog channels or 11 for the sonic channel. Equation numbers outside of this range will produce this error. The equation number must be in the range of.1 to 12 for analog channels and either 0 or 13 for the sonic channel. Equation numbers outside of this range will produce this error.
The order of the equation must be appropriate for the equation type selected. For example, an equation order of 5 is not valid for the mixed polynomial equation. This error occurred because (1) equations were enabled when sending Command 1, but the equation was never sent using Command 4, or (2) GET statement was issued before sending Command 4. Invalid units were selected for temperature when sending the temperature for the sonic to use. Valid values are from 0 to 4. A channel was selected that is not a valid channel. The channel numbers are 1-3, 11, 21, and 31. A data group was selected that is not valid. Valid values are from 0 to 5. The beginning-of-data selector must be 0 (for start of data) or 1 through the number of points collected. A number outside of this range will produce this error message. The end-of-data selector must be 0 (for end of data) or 1 through the number of points collected. A number outside of this range will produce this error message. In addition, the end of the data must not be before the beginning of the data. Digital probe has failed to read or write as commanded by the host. An attempt has been made to collect more data than can be stored in one data collection. This unit has 24K of memory dedicated to data storage, allowing up to 12K samples to be stored. (for example, 3072 samples per channel for 4 channels.) If more than this is attempted, an error will result. This error results when an attempt to return data is made and the data has not been collected. This error results when sending Command 6 and an invalid second parameter. This error results when sending Command 10 for a channel that does not have data stored. This error results when sending a Command 10 and selecting an algorithm that has not been defined. This error results when advanced algorithm is selected and the input parameters for it are not correct. This error indicates that the battery voltage is too low to safely write to FLASH memory and an attempt has been made to write to FLASH memory. The batteries should be replaced immediately for the unit to continue to perform properly.
