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

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
