Tutorial: Temperature Measurement with EasyData

A good way to get acquainted with LabPro is by performing a simple experiment. Using this tutorial,

you will take measurements using a Temperature Probe. Just follow the simple steps, and you are well

on your way to collecting and analyzing data with a calculator.

MATERIALS

TI graphing calculator

LabPro interface

Vernier Stainless Steel Temperature Probe

One 250 mL beaker or cup

100 mL hot water

PROCEDURE

1. Place about 100 mL of hot water into a 250 mL beaker or a cup.

2. Plug the Stainless Steel Temperature Probe into CH 1 on LabPro, and place the Temperature Probe

on the tabletop.

3. Start the EasyData application. EasyData will detect the auto-ID sensor, set the data collection

parameters, and display the current sensor reading. The experiment will collect temperature for 180

seconds.

4. Select

to begin data collection.

5. Wait about 10 seconds and place the Temperature Sensor into the cup of hot water as shown above.

A live graph will appear on the calculator screen. You can either allow EasyData to complete data

collection or press

to stop data collection.

6. After the data collection is complete, an autoscaled graph of the data will appear. Notice that the

probe does not read the new temperature instantly; it takes a little while to respond. This is a

characteristic of the sensor. Use the

or keys 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 that time. Move the cursor to find the

highest temperature and record that time. How long did it take for the temperature sensor to stabilize

at the water’s temperature?
