Easy Experimenting

The following program allows you to control the EA-100 from your CFX-9850G graphing calculator to perform simple experiments with the included probes. It allows experiments of up to 255 samples. Just enter the program into your calculator. Make sure you press EXE after each line, except for the highlighted command Send(List 1)lesson5.gif (1681 bytes) near the end of the program. That command needs a pause at the end. This pause command is found pressing SHIFT PRGM F5 (lesson5.gif (1681 bytes)).

To run the program, connect the CFX-9850G

to the EA-100 using the link cables. Now turn on both instruments. In PRGM mode (in the calculator) select this program and press EXE.


Answer all the questions. After answering the last question "HOW MANY SAMPLES 1--255?" you will see

- Disp-

on the calculator screen. At this point, the EA-100 reads READY. When the experiment is ready to run press TRIGGER. The experiment starts. When the experiment is over, the EA-100 reads DONE. At this point press EXE on the CFX-9850G so that the calculator retrieves the data.
