Quad Temperature Sensor
CARD 1A
Equipment Setup
Connect the PASPORT interface to a USB port on
your computer or to a USB hub.
On the Quad Temperature Sensor, insert one or
more temperature probes into the temperature port.
Connect the Quad Temperature Sensor to the
PASPORT interface. (If using an Xplorer in the
classroom, connect the Xplorer cable to your
computer.)
The software launches when it detects a PASPORT
sensor. Launch DataStudio.

Minus
buttons to change the rate. To set a new time
unit, click on the down arrow next to Hz and
select a new unit.
Change measurement
units:
In the Setup window, click on the down arrow
next to the appropriate temperature probe
number and select a new unit.
Scale to fit the data:
Click the
Scale-to-Fit
button on the Graph tool-
bar to automatically scale the data.
View data statistics:
On the Graph toolbar, click the

Equipment required
: PS-2143 Quad Temp. Sensor, PASPORT interface, DataStudio
(1.9.0 or later), up to four Fast Response Temperature Probes, adhesive patches/tape
1. Plug the PS-2143 Quad Temp. Sensor into a PASPORT interface.
2. Connect the PASPORT interface to a USB-compatible computer.
3. Launch DataStudio.
4. Plug a Fast Response Temperature Probe into each of the ports on the Quad
Temp. Sensor box.
5. (Optional): Calibrate each of the probes using the calibration procedure on card
2B.
6. Place a probe in each of the following locations: a) chest b) abdomen c) upper
arm and d) leg. (
Note:
To hold the probes in place, put an adhesive patch or
piece of medical tape over each probe.)
7. In DataStudio, open a Graph display. From the Data list, drag the icons for the
temperature measurements to the graph.
8. Click the
Start
button to begin collecting data.
9. Ask the student to exercise vigorously for about 10 minutes, and watch the data
while exercising. Stop and rest for about 10 minutes.
10. To end data collection, click the
Stop
button.
11. Compare the body temperature at each of the four locations during exercise. At
which location was the body temperature a) the lowest and b) the highest? At
which point was the change in temperature the greatest? Explain your answers.
Do more muscular parts of the body generate more or less heat than those
parts with more fat tissue?
12. (Optional): With disposable thermometers, have each student take his/her
body temperature. During exercise, which is higher, the core body temperature
or the skin temperature? Explain your answers.
13. (Optional): Using skin calipers, take a skinfold measurement for the chest,
abdomen, arm, and leg. Is there a relationship between the temperature
increase and the skinfold measurement?
