2Using the Setup Wizard
This section explains how to use the Setup Wizard to configure the EA-200 setup quickly
and easily simply by replying to questions as they appear.
If you need more control over specific sampling parameters, you should consider using the
Advanced Setup procedure on page 3-1.
kSetup Wizard Parameters
Setup Wizard lets you make changes to the following three EA-200 basic sampling
parameters using an interactive wizard format.
•Sensor (Select Sensor):
Specify a CASIO or VERNIER* sensor from a menu of choices.
*Vernier Software & Technology
•Total Sampling Time:
Specify a value within the range of 0.01 second to 30 days.
•Sampling Time Unit (Select Unit):
Specify seconds (sec), minutes (min), hours (hour), or days (day) as the time unit of the
value you input for the total sampling time (Total Sampling Time).
Sensor-specific settings
The type of sensor you select with “Select Sensor” settings affects the settings of the Setup
Wizard as described below.

uTo configure an EA-200 setup using Setup Wizard
Before getting started...
•Before starting the procedure below, make sure you first decide if you want to start
sampling immediately using the setup you configure with Setup Wizard, or if you want to
store the setup for later sampling.
•See sections 6-1, 7-1, and 8-1 of this manual for information about procedures required to
start sampling and to store a setup. We recommend that you read through the entire
procedure first, referencing the other sections and pages as noted, before actually trying
to perform it.
•To terminate Setup Wizard part way through and cancel the setup, press !i(QUIT).
1. Display the E-CON2 main menu (page 1-1).
2. Press 1(Setup EA-200). This displays the “Setup EA-200” submenu.
3. Press b(Wizard). This displays the “Select Sensor” screen.
4. Press 1to specify a CASIO sensor, or 2to specify a Vernier sensor. Select the
sensor you want from the menu of sensors that appears.
•Selecting a sensor (page 2-1) causes a screen for specifying the total sampling time to
appear.
2-2
Using the Setup Wizard
5. Use the number input keys to input the total sampling time. Just input a value. You will be
able to specify the unit (sec, min, hour, day) of the value you input here in step 7 of this
procedure (see "Sensor-specific settings" on page 2-1).
Note
•If you specify a total sampling time value in the range of 10 seconds to 23 hours, 59
minutes, 59 seconds, real-time graphing will be performed during sampling. This is the
same as selecting the Realtime Mode on the “Advanced Setup” screen.
6. After inputting total sampling time value you want, press w. This displays the “Select
Unit” screen.

8. Press number keys described below to specify what you want to do with the setup you
have configured.
b(Start Setup) ................ Starts sampling using the setup (page 8-1)
c(Save Setup-MEM) ...... Saves the setup (page 6-2)
d(Convert Program)....... Converts the setup to a program (page 7-1)
kUsing Setup Wizard to Configure a PhotoGate Setup
Connection of a Vernier PhotoGate requires configuration of setup parameters that are
slightly different from parameters for other types of sensors.
uu

uTo configure a setup for PhotoGate alone
1. Perform the first three steps of the procedure under “To configure an EA-200 setup using
Setup Wizard” on page 2-2.
2. On the “Select Sensor” screen, select [VERN] - [P-Gate] - [None].
•This causes a “Gate Status” screen to appear.
2-3
Using the Setup Wizard
7. Use number keys bthrough fto specify the unit for the value you specified in step 5.
•When you select a unit, the Final Setup Wizard screen appears on the display.
•“Open” means the photo path is not blocked, while “Close” means the photo path is
blocked.
•The gate status defines what PhotoGate status should cause timing to start, and what
status should cause timing to stop.
Open-Open ......Timing starts when the gate opens, and continues until it closes and
then opens again.
Open-Close ......Timing starts when the gate opens, and continues until it closes.
Close-Open ......Timing starts when the gate closes, and continues until it opens and
then opens again.
Close-Close......Timing starts when the gate closes, and continues until it opens and
then closes again.

kOutputting the Waveform of a Function through the Speaker
Normally, the Setup Wizard helps you configure setups for sensors connected to the EA-200.
If you select [CASIO] - [SPEAKR] - [Y=f(x)] on the “Select Sensor” screen, however, it
configures the EA-200 to output the sound that corresponds to a function that you input and
graph on the calculator.
uu

input a value of 200%. To lower the original sound by one octave, input a value of 50%.
12.After inputting an output frequency value, press w.
•This outputs the waveform between the start point and end point from the EA-200 speaker.
•If the sound you configured cannot be output for some reason, the message “Range
Error” will appear. Note that the supported output range is 200 to 4000Hz. If this
happens, press ito scroll back through the previous setting screens and change the
setup as required.
