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.
