2 Basic Steps for Configuring Sampling
Parameters
This chapter explains the basic operations you need to perform when configuring EA-200
sampling parameters from the E-Con EA-200 application. Before performing any of the
procedures in this chapter, be sure to connect the EA-200 to your ClassPad.
Configuring Parameters for Sampling with a Single Sensor
Use the [Single] tab of the Sensor Setup window to configure the parameters for a single
sensor.
• The procedure for configuring sampling settings on the [Single] tab is similar to a Windows
Setup Wizard. As you select a sensor and input setting values on the [Single] tab, settings
are adjusted automatically in order to make it possible to perform sampling properly. Even if
you are configuring settings for a single sensor, you should use the [Multiple] tab when you
want to configure all of the detailed settings yourself.
u To configure parameters for sampling with a single sensor
(1) Start up the E-Con EA-200 application.
• This displays the [Single] tab of the Sensor Setup
window.
• If the E-Con EA-200 application is already running
and another window (besides the Sensor Setup
window) is displayed, tap C to change to the Sensor
Setup window.

(3) Select the sensor you will use for sampling.
•Tap one of the tabs ([CASIO], [Vernier], [Custom]), and then tap the option button
next to the name of the sensor you want to select. For details about each of the
selectable sensors, see the “10 Sensor List”.
•Tapping the [Custom] tab displays a sheet for configuring the parameters of a userdefined custom probe. For more information, see “Using a Custom Probe” on page
3-12.
(4) After selecting a sensor, tap [Set].
• This closes the Select Sensor dialog box. The Sensor Setup window now shows the
name of the sensor you selected, along with boxes for the sample range and total
elapsed sampling time (Total Sampling Time).
• The example screen below shows what would appear if when the CASIO
Te mperature (°C) sensor is selected.

•Selecting some sensors will cause different parameters from those shown above to
appear. The following table explains you should go for more information about such
these sensors.
For this type of sensor: Go here for more details:
[CASIO] tab, [Microphone-FFT]
See “Microphone-FFT Parameters” on page 2-4
for more information.
[Vernier] tab, [Photogate] See “Photogate Sensor Parameters” on page 2-5
or [Photogate (Pulley)] for more information.
• The [Setup] menu is unavailable while [Speaker (Sample Data)] is selected on the
[CASIO] tab of the Select Sensor dialog box.
•When [Speaker (y = f(x))] is selected on the [CASIO] tab of the Select Sensor dialog
box, sampling is not performed by a sensor. Instead, the sound of the waveform of a
function input on the ClassPad is output from the EA-200’s speaker. See “6
Outputting a Function to the Speaker” for more information.
(5) Tap the [Total Sampling Time] box.
• This displays the Total Sampling Time dialog box.
Use the ClassPad
keyboard to input a
total time value.
Tapping here displays a menu of

hours, days) for the total time.
• If you specify a total sampling time value in the range of 10 seconds to 1 day, starting
the sampling operation will automatically enter the Real-Time mode and perform realtime graphing during sampling.
(6) To apply the current settings on the Total Sampling Time dialog box, tap [Set].
• This closes the Total Sampling Time dialog box, and displays the recalculated total
sampling time in the Total Sampling Time box on the Sensor Setup window. See the
“Tip” on the next page for information about how recalculation is performed.
(7) At this point you could configure advanced setup parameters, if you want.
•See “3 Setup” for more information.
(8) You can start sampling immediately or you can save the setup in memory for later
recall.
•To start sampling immediately, tap V. For more information, see “5 Executing a
Sampling Operation”.
•To store the setup in memory, tap [SetupMem] on the menu bar, and then tap [Store].

Tip
• When you use the above procedure to configure sampling parameters for a single sensor, the
sampling mode is selected automatically in accordance with the specified total sampling time. In
this case, the parameters of the Setup dialog box’s [Sample] tab and [Trigger] tab are also
configured automatically. The current sampling mode is indicated in the status bar.
For information about the mode indication in the status bar, see “E-Con EA-200 Application
Status Bar” on page 1-7. For information about the Setup dialog box’s [Sample] tab and [Trigger]
tab, see “3 Setup”.
•Tapping [Set] on the Total Sampling Time dialog box automatically configures the sampling
interval in accordance with the total sampling time that you input on the dialog box. The number
of samples value is calculate and rounded to the nearest integer. The number of samples integer
value is used to recalculate the total sampling time ({Number of Samples} × {Sampling Interval}),
and displays the result in the Total Sampling Time box on the Sensor Setup window. All of this
means that the value you input on the Total Sampling Time dialog box may not necessarily the
value that appears on the Sensor Setup window.

Fast, and Extended modes are normally available, while the Period mode is available in
special cases only.
k Normal Mode
This general-purpose mode can be used for a wide range of sampling applications. The
Normal Mode is used for relatively short sampling. When the Normal Mode is selected, you
need to specify the sampling interval, the number of samples, and the timing of the start
trigger.
k Real-Time Mode
Basically, the Real-Time Mode is the same as the Normal Mode, except that it produces a
real-time graph of data as it is sampled. Use this mode when you need to graphically monitor
changes in sampled values as they are being sampled.
k Fast Mode
Use this mode when sampling a sound waveform or when other very fast sampling is
required. This mode can be selected only when CH1 or MIC is being used for sampling. This
mode is selected automatically whenever sampling is performed using the microphone. In
this mode, the sampling interval can be set to a very short interval in the range of 20 애sec to
500 애sec.

k Extended Mode
The Extended Mode is the opposite of the Fast Mode in that it allows setting of a long
sampling interval. In this mode, the sampling interval can be set in a range of 5 to 240
minutes. This mode is best for sampling data like temperature or humidity over a long period.
k Period Mode
The Period Mode is for sampling data that changes periodically. Samples recorded by the
Period Mode differ from the samples recorded in other modes as shown below.

Other Modes Period Mode
Unlike the other modes that record time and sampled values, the Period Mode records the
number of samples (1st sample, 2nd sample, and so on) and the intervals between samples.
For details, see “Period Mode Parameters” on page 3-7.
Tip
• If you display the Setup dialog box from the [Multiple] tab of the Sensor Setup window, the [Mode]
box will allow selection of the Normal, Real-Time, or Extended mode only.
• Note that the availability of modes depends on the sensor being used for sampling. Certain
sensors allow selection of particular modes only.
• The currently selected mode is shown in the status bar of the Sensor Setup window.

to 99 seconds, and then tap [Set].
Start Trigger: Specify the event that triggers the start of sampling. You can select
from among the following options for this setting.
Tap Screen: This option specifies that sampling should start when
[OK] is tapped on the screen.
Count Down: This option specifies that sampling should start when the
end of a countdown is reached.
CH1: This option specifies that sampling should start when
CH1 channel input reaches a certain value.
SONIC: This option specifies that sampling should start when
SONIC channel input reaches a certain value.
Microphone: This option specifies that sampling should start when the
EA-200’s microphone detects a sound.
