Hello,

There are several ways to do the calibration. First, you should look over the information at www.vernier.com/arduino

Specifically, one way is to use the manual method described at:
https://www.vernier.com/engineering/arduino/analog-sensors/linear/

Another way, is to just use the sketch:
VernierAnalogAutoID or VernierAnalogAutoIDDisplay, which is in the dowload at the web site I first mentioned.

Finally, I am very close to posting a library to do all this calibration stuff. Send me a note in a week or so and I will send you the library files.
