Components Graphing Calculator interface Probe

Graphing Calculator

Interfaces CBL 2 – multiple probes Easy Link – single probe

Probes Easy Temp ph sensor

Calculator Software – Easy Data The EasyData App is a graphing calculator application. lets you collect, view, and analyze real-world data on certain TI-graphing calculators using Vernier USB devices or probes (Easy Temp and CBR2 motion sensor) which connect directly to the calculator.

Commonly used probes & sensors Temperature pH Light Voltage May actually use the probe or interpret data taken with the probe or sensor

Sample Procedure Turn on your TI-84 Plus graphing calculator and make sure that it is on the home screen Plug the probe into the EasyLink Interface and then plug the EasyLink into the USB port of the graphing calculator. The EasyData program will automatically start and the Main screen will be displayed

Collecting Data – Temp When starting a new data collection with a probe, select File and then the option New. Use the Setup menu to select the parameters for data collection. Select Start to begin data collection. Once data collection is complete, you will select Graph to choose the options for data analysis. Finally when you are finished, you will to select Quit to end the data collection session.

Probe Setup Graphing calculator Easy link or CBL Probe Collect data onto calculator Graph analysis Quick data collection

Sample Station – Temperature Use the temperature probe to detect temperature change in a chemical reaction It could also be done with a traditional thermometer

Sample Station – pH Determine the pH of various solutions using either pH probe or pH test papers.
