Instrumentation Laboratory Exercise 20
Run the program by clicking the Start button or the run (right
pointing triangle on the main menu bar) button. Verify that the
program accurately responds to changes in temperature.
Once you have confirmed that your program successfully measures
the diodes temperature, add a thermometer- type linear bar graph to
the display (found in the Display > Indicators menu):
Ensure that it reads near room temperature when you are not
touching the diode, and heats up to over 30 °C when clasped between
your fingers.
The last step is to add some form of recording so you can see how
quickly the temperature changes. The change in temperature can be
displayed by running the temperature into a Strip Chart display
(found under the Display menu). Add this feature at the bottom of
the screen and stretch it to the full width of the screen (as shown in
the figure below).
Also you will need to set up the X and Y axis. Go to the Properties
side bar on the left (you will need to select the Strip Chart first) and
click X, Y, Scales Properties. If the Properties side- bar is not displayed at
the left then you can right- click the Strip Chart box and click Properties
in the context menu.
Make the following setting:
• Y scale: minimum 20 to maximum 40.
• X scale: minimum 0 to maximum 200.
