Introduction This guidebook provides step-by-step instructions for collecting real world data using LabPro1–a portable, handheld data collection device–with a Texas Instruments graphing calculator and Vernier sensors2. DataMate supports all analog sensors and the Motion Detector. (Most users never need another program. For special probes, such as photogates, rotary motion sensors, radiation monitors, and drop counters, or special features, such as graph matching, we also have other calculator programs.

You may need to adjust screen contrast by holding down and then pressing the — key until the screen is legible.
LabPro Tutorials OVERVIEW The tutorials will teach you how to use the DataMate program. They will explore various data collection modes using a variety of sensors. There are five tutorials that cover the most widely used forms of data collection: time graph data collection, events with entry data collection, and using the LabPro as a stand-alone device (without a calculator connected).
LABPRO TUTORIAL #1: TEMPERATURE MEASUREMENT WITH DATAMATE AND AUTO-ID SENSORS A good way to get acquainted with LabPro is by performing a simple experiment. This particular tutorial will investigate the response time of a Temperature Probe using the DataMate program in Time Graph mode. Just follow the four easy steps and you are on your way to becoming comfortable with LabPro and DataMate.
6. Check that LabPro has power, the link cable is properly connected, and that the LabPro unit is receiving power. This screen will appear until the link problem is fixed. 7. Press CLEAR to reset the program. This is the Main screen that appears after the calculator and interface are communicating. In this example, DataMate automatically identified the Temperature Probe, displayed the channel it was connected to, and displays the current live reading.
LABPRO TUTORIAL #2: USING A NON AUTO-ID SENSOR LabPro will automatically identify auto-ID sensors; however, you may have a number of older sensors that are not automatically recognized. These will frequently be sensors with a round 5pin DIN plug, which require a DIN-BTA adapter to connect to LabPro. The DIN-BTA adapter is a small plug with a round 5-pin DIN plug on one side, and a white, flat British Telecom plug on the other.
6. DataMate acts as a meter on the Main screen, and the screen updates every three seconds. The pH is displayed in the upper right-hand corner. 7. Remove the pH Sensor from the sensor storage solution bottle by unscrewing the lid. Carefully remove the bottle, leaving the cap on the sensor body. Rinse the tip of the sensor with distilled water and place the sensor tip into a beaker containing sensor soaking solution. 8. Take the pH measurement of your different liquids.
LABPRO TUTORIAL #3: EVENTS WITH ENTRY AND BOYLE’S LAW The Events with Entry mode collects one data point each time you press ENTER and then asks you to enter a corresponding value for that point. This tutorial will guide you through the setup procedure of an experiment using Events with Entry to investigate the relationship between the pressure and volume of a gas. MATERIALS TI graphing calculator LabPro interface Vernier Gas Pressure Sensor DataMate program Figure 1 PROCEDURE 1.
5. A list of modes will appear in the SELECT MODE screen. Press the number preceding EVENTS WITH ENTRY. You will be returned to the Setup screen. Then select OK to return to the setup screen. 6. Select OK to return to the Main screen. You are now ready to collect pressure and volume data. It is best for one person to take care of the gas syringe and for another to operate the calculator. 7. Select START.
LABPRO TUTORIAL #4: COLLECT MOTION DATA The Vernier Motion Detector measures the distance to an object using echoing ultrasonic sound waves. LabPro then calculates the velocity and acceleration. This tutorial will show you how to change the length of an experiment and make a graph of a person walking. MATERIALS TI graphing calculator LabPro interface DataMate program Motion Detector walk back and forth in front of Motion Detector PROCEDURE 1.
6. Select START to collect data. You will notice a fast clicking sound coming from the Motion Detector. Wait one second, then walk slowly away from the Motion Detector. Stop for a moment, then walk toward the Motion Detector. The screen will give a live graph. 7. After data collection is complete, you will be presented with a screen asking you which graph to view. For starters, position the arrow next to DIG-DISTANCE, and press ENTER . A graph (which may look something like this) of distance vs.
LABPRO TUTORIAL #5: LABPRO AS A STAND ALONE DEVICE The Quick Set-Up feature of LabPro lets you collect data without a calculator connected to the interface. Only auto-ID sensors can be used with Quick Set-Up. In this mode, LabPro samples at default rates pre-set in DataMate. Data will be taken continuously and stored in the memory of LabPro. If you want to stop data collection earlier than the pre-set time, press the START/STOP button.
e. Select RETRIEVE DATA. The data are retrieved from the memory of LabPro. 1. Scroll the cursor across the graph using the calculator’s arrow keys. At which point did the Stainless Steel Temperature Probe change hands? Note: If you start DataMate and connect a calculator during data collection, a screen showing the collection status will appear.
The DataMate Program in Detail OVERVIEW This section describes DataMate in detail. Although the program is designed to enable you to gather data with one or two pushes of a button, there are a number of options (setting up sensors, data collection modes, etc.) that may require more detailed explanation. We recommend that you read this section of the manual in order from start to finish. QUICK START The following section illustrates the fastest way to collect data using DataMate with autoID sensors3.
If the calculator fails to communicate with LabPro, this error message appears. Check that LabPro has batteries or is powered by the AC adapter and that the link cable is properly connected. This screen will appear until the link problem is fixed. This is the Main screen. The top half of the screen shows the current sensor setup and data collection mode. The bottom half displays the menu options. A low battery icon appears in the lower right hand corner if the LabPro batteries require replacement.
SETUP OPTION Sensors LabPro will automatically identify auto-ID sensors; however, you may have a number of older sensors that are not automatically recognized. These will frequently be sensors with a round 5-pin DIN plug, which requires a DIN-BTA adapter to connect to LabPro. The DIN-BTA is a small plug with a round 5-pin DIN plug on one side, and a white, flat British Telecom plug on the other. Using these sensors is not a problem, since only a couple extra steps are required to set up experiments.
Data Collection Modes For each Vernier sensor, DataMate loads a default experiment appropriate for the sensor. The default data collection mode for all sensors is Time Graph (collecting data points at a predetermined rate for the specific sensor). To choose another mode, or change the time graph data collection parameters, position the cursor using the arrow keys opposite MODE and press ENTER to see the SELECT MODE screen. In the LOG DATA mode, data are collected with auto-ID sensors using Quick Setup.
3. To change the type of triggering, select CHANGE TRIGGERING. In the example shown, there are two types of triggering: • • • LabPro will trigger the start of data collection based on a change in the data being collected. (This is called threshold triggering.) For MANUAL TRIGGER, the LabPro will start collecting data when the START/STOP button on LabPro is pressed. If you choose NONE, no special triggering will be set. 4. Press the number beside the type of triggering you want.
EVENTS WITH ENTRY is used for non time-based data collection such as triggering for titrations, Boyle’s law, etc. Data are collected one point at a time and only when the ENTER button on the calculator is pressed. You are then prompted to enter a corresponding value. SINGLE POINT data collection is used to collect one averaged data point. The interface will collect data for 10 seconds and report a single, averaged value for each sensor on the calculator screen.
4. Key in 4 and press ENTER . 5. Repeat steps 3 and 4 for the pH-10 solution. 6. Select OK to return to the Setup screen. To calibrate the pH sensor by entering values manually, follow these steps: 1. On the Setup screen, move the cursor to the sensor you want calibrated and select CALIBRATE. 2. Select MANUAL ENTRY. 3. Key in the slope and press ENTER . 4. Key in the intercept and press ENTER . The Calibration screen is displayed with the new values. 5. Select OK to return to the Setup screen.
Select SAVE EXPERIMENT to either save a setup with or without data. When you have entered the settings for an experiment but haven’t taken data, only the settings are saved. If you have entered the settings and taken data, both are saved. Follow the steps to save an experiment. • From the EXPERIMENT MENU screen, select SAVE EXPERIEMENT. • Type in a name and press Setup menu reappears. ENTER . The experiment is saved, and the LOAD EXPERIMENT.
GRAPH OPTION The Graph screen automatically appears when you are finished collecting data or when Graph is chosen from the Main screen. Two conditions determine the Graph screen: • If one analog channel is active then a graph of your data is presented when data collection is complete, or if two of the same type of analog sensors are plugged in. • If more than one channel is active or you have collected data using the motion detector, you will be presented with a list of available channels to view.
• Press ENTER and return to the RESCALE GRAPH screen and select another scale to see the graph with other scale options. • When you are done viewing the graphs, press Rescale Graph screen, then select RETURN. ENTER to return to the Selecting MORE on the Graph screen enables you to plot alternate data lists in a graph. L1, L2, L3 and L4 refer to the lists in which your data are stored. For example, L3 vs. L1 will graph the data in List 3 versus the data in List 1.
The first five options will display the current value for that variable and prompt you for a new value. Each time a variable is changed, the calculator regraphs the data and the model equation. Option 6 will turn off the model and return you to the ANALYZE MENU screen. The parameters are reset upon leaving modeling. STATISTICS finds the mean, min, max, standard deviation, and number of data points of a selected region. After selecting this option, choose a graph from the displayed list.
CHECK BATTERY • will display the status of LabPro’s battery. From the TOOLS menu, press CHECK BATTERY. • If battery charge is adequate you will get the following message. QUIT OPTION Select Quit to leave DataMate and return to the home screen of the calculator. On the TI-89, TI-89 Titanium, TI-92 and TI-92 Plus calculators you must press F5 or HOME to return to the home screen. To see the last graph select zoomstat as appropriate for the calculator model.
Supplemental Programs We have written supplemental programs for special sensors, such as photogates and radiation monitors, or for special applications, such as motion matching or managing the Flash memory of your interface. One feature of the latest operating system for LabPro and CBL 2 is the ability to transfer the DataDir program instead of the DataMate program to your calculator from the interface. With DataDir on your calculator, you can then retrieve supplemental programs from the interface.
Updates for your interface can be found on the Vernier web site at www.vernier.com/downloads/index.html and on the TI web site at education.ti.com. 1.

Appendix A: Battery and Adapter Information OPERATING POWER REQUIREMENTS • • • • The LabPro is designed to operate with four AA alkaline batteries. Factors that affect battery life are the actual time that the LabPro is collecting data and the amount of current used by connected probes during your experiments. To extend battery life in the classroom we recommend that you use an approved power adapter.
APPROVED AC POWER ADAPTERS The LabPro 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 model IPS power supply is an AC-to-DC power adapter approved for use with the LabPro. The TI-Presenter power supply can also be used with LabPro. The use of other power adapters is strongly discouraged. To order an adapter, call Vernier at 1-503-888.837.
Appendix B: DataMate and Calculator Specifics There are functional and operational differences between the various types of TI graphing calculators. This Appendix describes those differences. CALCULATOR DIFFERENCES Because of the differences in memory between the calculators, there are some differences in functionality between the different versions of DataMate. See also the troubleshooting guide in Appendix E for information on the maximum number of data points each calculator can collect.
Appendix C: LabPro Products, Calculators, and Sensors Here are some of Vernier sensors that are available. Take a look at the Vernier catalog or check out the web site www.vernier.com for a full listing of LabPro and CBL 2 products.

Appendix E: DataMate Troubleshooting Guide Screen Explanation This screen appears when too much time has passed on a screen without activity. This timeout feature takes advantage of the Automatic Power Down (APD) feature of the calculator and LabPro to conserve battery power. • Press YES to continue the program. • Press NO to quit. This screen appears when LabPro is not connected to the calculator or when LabPro needs new batteries. • Check the connection between LabPro and your TI calculator.
Screen Explanation This screen appears when the LabPro is disconnected from the calculator or when the LabPro loses power. When the LabPro and calculator are reconnected, the calculator may not recheck the sensor setup, and this error results. Press CLEAR to reset the LabPro to initial conditions (In general, whenever you see something on the screen that does not look correct, press CLEAR to reset.), and then set up the channel again.
Screen Explanation This screen usually appears when the user is running DataMate and one of the DataMate subprograms has been deleted from the calculator memory. (This applies to the TI-73, 82, 83, 86, 89, 93, and 92 Plus). 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 LabPro to the calculator and begin again.
Screen Explanation This screen appears when the user tries to run the Ranger program using the TI-89/89 Titanium/92/92 Plus after using the DataMate program. This is caused by a conflict in some information left over in List 5. The information in the list cannot be used properly, so the calculator gives a Dimension error. To correct this, go into the calculator’s memory mangement and delete List 5 (L5). This screen can appear on the TI-83 Plus.
Appendix F: DataMate Sensor Setup Default Settings The table that follows shows the default settings used by the DataMate program as well as the Quick Setup feature of LabPro. This sensor and calibration information applies only to Vernier and TI sensors. The use of other manufacturers’ sensors may require calibration or the manual entry of that sensor’s calibration information into DataMate. Note: Default settings apply only when using a single sensor that is connected to Channel 1.
