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. Installing and using supplemental
programs is explained in the section titled Supplemental Programs.)
By following this guidebook, you will:
• identify the necessary equipment
• connect the equipment
• load the data collection program, DataMate, on your calculator
• collect data by following the tutorials
REQUIRED EQUIPMENT AND SUPPORTED CALCULATORS
To collect data with LabPro and a calculator, the following materials are needed:
• LabPro System: LabPro interface, AC power supply, calculator link cable, DataMate
calculator program, calculator cradle, user’s manual, and voltage sensor.
• A TI-73, TI-73 Explorer, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus,
TI-84 Plus Silver Edition, TI-86, TI-89, TI-89 Titanium, TI-92, TI-92 Plus, or Voyage 200
graphing calculator.
Because of their Flash ROM capabilities, we recommend the TI-73, TI-73 Explorer, TI-83
Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, TI-89, TI-89
Titanium, or Voyage 200 calculators. If you are using version 2 of the AMS software for
the TI-89 or TI-92 Plus, you must update to version 2.04 or newer.
• Sensors: Sensors can be divided into two basic types—analog and digital. Examples of
analog sensors are temperature probes, pH sensors, force sensors, etc. Up to four analog
sensors can be connected to LabPro. An example of a digital sensors is a motion detector.
Up to two digital sensors can be connected to LabPro.
Optional (but recommended)
• Four AA batteries for remote data collection.
• Graphical Analysis, Logger Pro, TI Connect™, and/or
TI-GRAPH LINK™ software.
1
LabPro can also be used as a computer interface using Logger Pro® software. Further LabPro resources,
the LabPro Manual and LabPro Technical Reference Guide, are available on the LabPro CD.
2
The CBL 2 can also be used with Vernier sensors to collec t data with Texas Instruments graphing
calculators. The directions contained herein apply to both interfaces, except where noted.
DataMate Guidebook 3
Connect the Equipment and Load DataMate onto your Calculator
CONNECT THE HARDWARE
1. Insert the upper end of the calculator into the cradle.
2. Press down on the lower end of the calculator until it snaps into place.
3. Slide the bottom of the cradle onto the top of LabPro until it clicks in place.
4. Plug one end of the LabPro-to-calculator cable into the I/O port in the lower end of
the calculator, and the other end into LabPro.
PROVIDE POWER TO LABPRO
Batteries or AC power can power LabPro. To use LabPro with batteries, remove the
battery compartment cover from the underside of the interface. Insert four alkaline AA
batteries and replace the compartment cover. Shortly after connecting to power, the
interface will run through a self-test. You will notice a series of beeps and blinking lights
(red, yellow, then green) indicating a successful power up. If the self-test is not
successful, make sure that the batteries are installed correctly and that they are still
useable.
To use LabPro with the AC power supply, plug the round plug on the 6-volt power supply
into the side of the interface. Shortly after plugging the power supply into the outlet, the
interface will run through a self-test. You will notice a series of beeps and blinking lights
(red, yellow, then green) indicating a successful power up.
RESET CALCULATOR (OPTIONAL BUT RECOMMENDED)
The TI-82, TI-83, and TI-92 calculators are very limited in memory. To allow room for
data storage and processing, you must remove all other programs and data from the
calculator. Other calculators have sufficient memory to hold other data and programs
along with DataMate, but to maximize the amount of data you can collect you should
remove other programs. The easiest way to do this is to reset the calculator. Warning:
Resetting the calculator will remove all programs and data. Back up any needed
programs or data before proceeding.

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).
• 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. In Tutorial #1 you will learn how to start the program and
start collecting data right away.
Note: It is important to start with Tutorial #1, as it provides necessary setup
information. Beginning with Tutorial #2 if you are using a non auto-ID sensor.
• You may have older sensors that don’t have the auto-ID ability. The directions for
setting up older sensors are given in Tutorial #2.
• Some experiments are not time based; instead they are event based. A pH titration is
an example. Tutorial #3 will guide you through the events with entry data collection
procedure using a pressure sensor.
• Tutorial #4 will show you how to set up and conduct an experiment with the Motion
Detector.
• Tutorial #5 will show you how to set up LabPro as a stand-alone device for data
logging, then transfer the data back to your calculator for viewing.

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.
MATERIALS
TI graphing calculator Vernier Stainless Steel Temperature Probe
LabPro interface One 250 mL beaker or cup
DataMate program 100 mL hot water
PROCEDURE
Connect the hardware.
1. Plug the link cable into the link port of the TI graphing calculator and LabPro.

you choose INTERFACE, the calculator will continue to attempt linking
with LabPro. If the link still cannot be established, the error message
shown below will appear.
DataMate Guidebook 7
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.
DataMate also sets up a default time graph experiment for auto-ID
sensors. The default settings for the temperature sensor are for a 180
second time graph.
8. You’re ready to collect data. Select START by pressing the
2
key.
(During collection, the graph is scaled to the default settings). Wait about
five seconds and place the Stainless Steel Temperature Probe into the cup
of hot water.
Data collection will stop after 180 seconds (or you can press the
STO
key to stop the data collection before the 180 seconds has elapsed).
9. After the data collection is complete, an autoscaled graph of the data will
appear. Notice that the probe did not read the new temperature instantly;
it took a little while to respond. This is a characteristic of any sensor. Use
the or keys (or the cursor pad on the TI-92) to examine the
data points along the displayed curve of temperature vs. time. As you
move the cursor right or left, the time (X) and temperature (Y) values of
each data point are displayed below the graph. Move the cursor to the
point when the probe was first placed in the hot water. Record the time
value. Move the cursor to find the highest temperature and record the
time value. How long did it take for the Temperature Probe to stabilize at
the water’s temperature?
10. Press
ENTER
to return to the Main menu, then select QUIT to quit the program.
To summarize: All you need to do to collect data as a function of time with auto-ID sensors is
connect the hardware, start DataMate, and select START. Time graph parameters can be
changed within DataMate. Other data collection methods, using different modes, will be
discussed in the tutorials that follow.

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. Using these sensors is not a problem, since only a couple extra steps are required to
begin data collection. This tutorial will show you how to set up non auto-ID sensors (pH is just
an example) and take some data using the DataMate program in meter mode.
MATERIALS
TI graphing calculator pH System with a DIN-BTA adapter.
LabPro interface a number of liquids in which to measure
DataMate program solution (cola or any soft drink, milk,
vinegar, window cleaner, etc.)
distilled water beaker to hold liquids
PROCEDURE
1. Connect the pH System to the DIN-BTA adapter then plug the adapter
into Channel 1. Use the link cable to connect the TI graphing calculator to
the interface. Firmly press in the cable ends.
2. Turn on the calculator and start the DataMate program.
You will notice that DataMate has not recognized your pH System. That’s
because you have one of the older, non auto-ID sensors that LabPro cannot
detect. It must be manually set up. Press
CLEAR
to reset the program.
3. Press
1
to select SETUP.
4. This is the Setup screen. Here you can change the sensor, units of
measurement, and data collection parameters. Notice that the cursor is on
CH1, indicating that you can press
non-auto pH system to channel 1, press
ENTER
to modify that channel. To add a
ENTER
.
5. A list of probes will appear. Press the number preceding PH. You will be
returned to the Setup screen. By choosing a sensor type, DataMate loads
the default calibration and data collection rate for that sensor. Select OK by
pressing
1
to return to the Main screen.
DataMate Guidebook 9
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. Watch the readings in
the corner change. Between measurements, rinse the sensor with distilled
water. Switch the liquids and write down the readings. Note that
DataMate does not record data in Monitor mode. Although this tutorial
does not have you use the function, by selecting START you could collect
pH vs. time data.
When you are done, rinse the sensor with distilled water and return it to the sensor
soaking solution. Select
QUIT and exit the DataMate program.
