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

C L E A R

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

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.
