LabPro Tutorial 1: Temperature Measurement with Data Pro
A good way to get acquainted with Data Pro is by performing a simple experiment. This
particular tutorial will investigate the response time of a Temperature Probe using the Data
Pro program in Time Graph mode. Just follow the four easy steps and you are on your way
to becoming comfortable with LabPro.
MATERIALS
Palm OS device Vernier Stainless-Steel Temperature Probe
LabPro interface One 250-mL beaker or cup
Data Pro program 100 mL hot water
PROCEDURE
1. Connect the Palm OS device to the LabPro using the interface cable.
2. Plug the Stainless Steel Temperature Probe into Channel 1 of the LabPro.
3. Be sure the LabPro unit is powered (using its AC power supply, or 4 AA batteries).
4. Press the power button on the Palm OS device.
5. To start up the Data Pro program, tap , the Data Pro icon, on the
Applications screen of the Palm OS device.
6. You are now on the Main screen of Data Pro. Tap to reset the
program. With an auto-ID sensor, Data Pro will identify the sensor and
show correct readings. It also shows the default mode, e.g., Time Graph, and tells the
default data-collection parameters (e.g., 1 second/sample, 180 samples).
7. You are now ready to collect data. Tap . During data collection,
you will see the minimum and maximum temperature values displayed
for the y-axis temperature range. In addition, the live reading of the
Temperature probe will be displayed in the upper-right side of the
graph. Wait about five seconds and place the Temperature Probe into
the cup of hot water. Data collection will stop after 180 seconds (or if
you tap
before the 180 seconds has elapsed).
