The program below, PRESSURE, is used by your TI-92 together with the TI-CBL to make and record pressure readings. If your workstation has a TI-Graph Link cable and the appropriate software installed then you can download the program from this computer to the calculator. Otherwise you can transfer the program from your instructor's TI-92 using a linking cable or as a last resort type it in.
After you've entered the program into your TI-92, connect the TI-92 to the CBL using the linking cable and plug the cable from the pressure sensor into the channel 1 port of the CBL. Make sure that the TI-CBL is turned on. Run the program PRESSURE by typing PRESSURE() and then pressing ENTER from the home screen. You should see a prompt asking you to set the plunger at 20 and then press TRIGGER on the TI-CBL.
Now set the plunger at 20 cubic centimeters. Then open and close the pressure release valve. For the remainder of this experiment the pressure release valve should remain closed. You should see the READY indicator on the TI-CBL and also see a pressure reading. Now press the TRIGGER key on the TI-CBL. It will make one pressure reading that will be recorded by the TI-92. You should see a prompt asking you to set the plunger at 19 and then press TRIGGER on the TI-CBL.
Follow the instructions -- set the plunger at 19 cubic centimeters and then press the TRIGGER key on the TI-CBL. It will make one pressure reading that will be recorded by the TI-92.
Continue in this way, making and recording a series of pressure measurements with the volume = 20, 19, 18, 17, ... 5.
When you are done collecting the data you can look at it by setting the TBLSET screen as shown below.
