E-CON4 Application (English)

Important!

• All explanations in this section assume that you are fully familiar with all calculator and Data Logger (CMA CLAB* or CASIO EA-200) precautions, terminology, and operational procedures.

CLAB firmware must be version 2.10 or higher. Be sure to check the firmware version of your CLAB before using it.

• For information about CMA and the CLAB Data Logger, visit http://cma-science.nl/.

1. E-CON4 Mode Overview

The first time you enter the E-CON4 mode, a screen will appear for selecting a Data Logger.

Data Logger Selection Screen

Press F1(CLAB) or F2(EA-200) to select the Data Logger you want to use.

Selecting a Data Logger will cause the sampling screen (Time-based Sampling screen) to appear.

Use the sampling screen to start sampling with the Data Logger and to view a graph of samples.

CLAB

EA-200

There are four sampling modes (sampling screens), described below.

1. Time-based Sampling ... Draws a graph simultaneously as sampling is performed. Note, however, that the graph is drawn after sampling is finished when CH1, 2, or 3, SONIC, or [START] key is specified as the trigger source, or when the sampling interval is less than 0.2 seconds.
2. Fast Sampling ... Select to sample high-speed phenomena (sound, etc.)
3. Period Sampling ... Select to perform periodic sampling starting from a start trigger event and ending with an end trigger event.
4. Manual Sampling ... Sampling is performed when the [EXE] key is pressed. Up to 100 samples can be taken by manual operation. Sampled data is stored in the Statistics mode list. (CLAB only)

5. Mic & Speaker Mode ... Select to sample sound using the built-in microphone. You can also output a waveform using the built-in speaker. (EA-200 only)

6. The Data Logger selection screen will not appear from the next time you enter the E-CON4 mode. Instead, the Time-based Sampling screen for the selected a Data Logger will appear first.

7. To change the Data Logger, change the setting on the E-CON4 setup screen.
8. Connecting a Data Logger that is different from the one specified for the calculator will cause an error message to appear. If this happens, use the setup screen to change the "Data Logger" setting.

E-CON4 Specific Setup Items

The items described below are E-CON4 setup items that displayed only when the

SHIFT MENU (SET UP) operation is performed in the E-CON4 mode.

2. Sampling Screen

Changing the Sampling Screen

On any sampling screen, press F5 (MODE) to display the sampling mode selection screen.

CLAB

EA-200

Use keys 1 through 4 to select the sampling mode that matches the type of sampling you want to perform.

Time-based Sampling Screen

CLAB

EA-200

• CLAB has three channels named CH1, CH2, and CH3.
• EA-200 has four channels named CH1, CH2, CH3, and SONIC. Note, however, that up to only three channels can be used for sampling at any one time. If you try to start sampling with four channels at the same time, a “Too Many Channels” error will appear.

Fast Sampling Screen

CLAB

EA-200

• Both CLAB and EA-200 can use CH1 only.

Period Sampling Screen

CLAB

EA-200

• With CLAB, only CH1 can be used.
• EA-200 has two channels (CH1 and SONIC). However, only one of these can be used.

Manual Sampling Screen (CLAB Only)

CLAB

• There are three channels named CH1, CH2, and CH3.

■ Mic & Speaker Mode Screen (EA-200 Only)

On the sampling mode selection screen, pressing 4 (Mic & Speaker Mode) displays the dialog box shown below.

Select Microphone or Speaker.

- Selecting Microphone

This displays the dialog box shown below.

"Sound wave" records the following two dimensions for the sampled sound data: elapsed time (horizontal axis) and volume (vertical axis).

"FFT" records the following two dimensions: frequency (horizontal axis) and volume (vertical axis).

• Selecting "Sound wave" here will display the Mic & Speaker Mode screen.

• Selecting "Sound wave & FFT" or "FFT only" will display the dialog box shown below.

Select FFT Range

2 - 1000Hz: [F1]

4 - 2000Hz: [F2]

6 - 3000Hz: [F3]

8 - 4000Hz: [F4]

Selecting an option automatically configures parameters with the fixed values shown in the table below.

Option Parameter	2 - 1000Hz: F1	4 - 2000 Hz: F2	6 - 3000 Hz: F3	8 - 4000 Hz: F4
Frequency Pitch	2 Hz	4 Hz	6 Hz	8 Hz
Frequency Upper Limit	1000 Hz	2000 Hz	3000 Hz	4000 Hz
Sampling Period	61 μsec	31 μsec	20 μsec	31 μsec
Number of Samples	8192	8192	8192	4096

This strip calls the Time-based Sampling screen. This strip provides access to almost all executable functions, including detailed Data Logger setup and sampling execution; graphing and Graph Analysis Tools, etc.

Note

• Using an E-CON Top strip to configure a setup causes the setup information to be registered in the applicable strip. This means that the next time you open the strip, sampling can be performed in accordance with the previously configured setup information.

E-CON Result strip

This strip graphs sampled data that is recorded in the strip. The sampled data is recorded to the strip the first time the strip is executed.

E-CON Strip Memory Capacity Precautions

• The memory capacity of each E-CON strip is 22.5 KB. An error will occur if you perform an operation that causes this capacity to be exceeded. Particular care is required when handling a large number of samples, which can cause memory capacity to be exceeded.
• Always make sure that FFT Graph is turned off whenever performing sampling with the microphone. Leaving FFT Graph turned on cause memory capacity to be exceeded.
• If an error occurs, press SHIFT (□) to return to the eActivity workspace screen and perform the procedure again.
• For information about checking the memory usage of each strip, see "To display the strip memory usage screen" on page 10-21.

For details about eActivity operations, see Chapter 10 of this manual.
