To perform datalogging, you will need the following items:
We presently support two models of Casio datalogging devices. The Casio EA100 (now superseeded) and the Casio EA200.
We recommend three sites where you can obtain programs from the CFX and FX series of graphic calculators that drive the dataloggers. On these sites you can also download ready to use experiment worksheets.
The three sites are:
this site (see below for programs, especially for probes not featured on other sites)
Casio's Japan site (programs and experiments that are in the EA-200 manual)
If you are using a fx 9860G AU, FX2.0 Plus or ClassPad we suggest you use the freely available ADD-IN called ECON (for the EA100) or ECON 2 (for the EA200). They are available from the Casio Worldwide website.
The programs below have been purpose written for the Casio 9850GB Plus graphics calculator to make it drive the EA100 and EA200 data logger. The programs are designed to have the EA100/200 collect data (using a variety of probes), transfer the data from the EA100/200 to the calculator and then produce graphical displays of the data. You can also perform your own analysis on the data once it is in the calculator.
The programs marked with an asteriks (*) have been written to perform specific tasks and allow students to see the data appear as the experiment progresses. Some of these also make it possible to use some of the more 'special' probes.
This program is for the Casio 9850 when linked to the EA200 and using the Vernier Motion Sensor.
It records the motion of up to 2 objects. You can choose the time between samples and the number of distance measurements you want to collect. The program asks the EA200 to post process the data and thus returns four things:
time
distance
velocity
acceleration
The data for each is returned to List 1, 2, 3 and 4 respectively into File 2 for the first object launched and into File 3 for the second object launched. Files can be selected after exiting the program in the List Menu of the 9850 by choosing SHIFT then MENU. The 9850 has 6 files each containing 6 lists.
In between launching objects you have the option to view a number of graphs.
All steps you need to follow are listed by the program on the calculator so there is actually nothing for students to learn about the set up prior to using this.

For any experiment where conductivity of a solution is required to be measured, eg. comparing diffusion rates of different strength saline solutions. Allows three different situations to be recorded and compared graphically.
Requires one Vernier Conductivity probe.

It allows the user to use the light probe that comes with the EA 200 (no EA 100 version of this code - yet?) to measure ligt intensity from a point source at various distances from the source. A lovely inverse square relationship is developed.
The program is written to measure the maximum intensity of the light source being used (at a point a little distance from it) and then is written to allow the user to take less than or equal to 9 measurements from upto 2 metres from the light source.
