Programs for the EA100 Data Collector

Casiolab 7400+ is a menu driven program using Casio's 7400+ Middle School Graphing Calculator and the EA100 data collector. The program allows you to setup, collect, and graph data for about 22 Vernier or Pasco probes.

This program is specific to the Vernier Pressure Probe that plugs into the EA100.

Use this program to choose Sample Rate, Sample Time, and Number of Samples for the EA100.Choose from 22 different programs callibrated to use Vernierprobes. The program was created by Steve Nichols.

Run this while you are using the 9850+, several pretty graphs are drawn on the screen. This is a good show and tell of what the calculator is capable of graphing.

Have your algebra students practice graphing by using this program that creates random graphs and asks for you to match the motion with the motion detector.

A program that allows you to calculate velocity and acceleration of a falling object using the motion detector.

Use this to calibrate the PH Probe.

PHOTO-G contains programs that work with one or two photogates: 

• PG-TIME.CAT works with two photogates and a dual photogate adapter. It is triggered by an object going through either photogate and ends when an object triggers the other photogate.
• PHOTO-G.CAT uses a picket fence to trigger the photogate. The gate is triggered by the leading edge of each black strip on the photogate.

Either drop a picket fence through the photogate to measure gravity directly or set it up at an angle using an air track. The program automatically develops velocity and acceleration from the time and distance data gathered by the photogate and EA-100. When viewing the velocity versus time graph press one to calculate a linear regression of this graph.

Note: When the PHOTO-G.CAT program asks for number of samples input the number of complete cycles (from beginning of black strip to beginning of black strip) on your picket fence.

Calculate the PH value of a solution.

Show change in brightness of a light source in realtime by using this program and the light probe.

Show change in temperature by using this program and the temperature probe and the results are displayed in "realtime".

A program that uses the motion detector to plot movement or distance relative to time, with a "realtime" display.

Some more Realtime programs - each one has been modified to suit the creators' needs: 

• realtime.cat, 
• realtime2.cat,
• realvolt.cat

Transfer two sets data from the EA100 to List1 and List2 of the graphing calculator. Uses time, and Channel 1, as the data that is transmitted.

A program which uses the motion detector and graphs distance vs time.

A program using the motion detector which calculates velocity of an object in relation to time.

Convert to Celsius or to Fahrenheit using this program.

Program created by Dick Rezba at Virginia Commonwealth University. Take timed readings using either microphone, ph, force, or pressure probes.

Also by Dick Rezba, VCU, Similar to Timedpgm, but allows you to trigger samples independent of time. The same four probes are used.

A program that uses a light probe to trigger collection of data for a moving car. This also has an accompanying student activity.
