E-CON5 App (Data Logger Controller)

The E-CON5 app is a dedicated controller for the CMA CLAB data logger. CLAB can use its built-in accelerometer and a variety of external sensors that can be connected to CLAB (voltage sensor, temperature sensor, motion sensor, etc.) to measure various phenomena, and then collect and store the measured data.

 

The E-CON5 app provides the following functions:

Configuration of measurement methods

Automatic recognition of sensors and manual configuration of sensors

Collection of data measured by sensors

Display and analysis of measured data using graphs and tables

Saving of measured data to a list variable or CSV file

Saving of measurement setups (including sensor settings, measurement method settings, and graph drawing settings) to a file, and management of saved setups

Important!

To use the E-CON5 app, the calculator must be connected to CLAB. Use the dedicated 2.5 mm plug cable to connect the calculator and CLAB. This cable is included in the optional SB-2000 (a set consisting of a USB cable and 2.5 mm plug cable).

For proper operation, you must update CLAB’s firmware to the latest version. For CLAB product information and firmware, visit the CMA website.
https://cma-science.nl/

This section assumes that you are already familiar with CLAB precautions, terminology, and operations. For details about CLAB, refer to the instruction manual included with CLAB or visit the CMA website.

Introduction

Connecting the Calculator and CLAB

  1. Turn on the calculator, select h > E-CON5, and then start the E-CON5 app.

  2. This displays the E-CON5 app top screen.

    If “CLAB disconnected” appears on the calculator, it means CLAB is not connected to the calculator.

  3. Use the 2.5 mm plug cable to connect the calculator’s 2.5 mm jack to CLAB’s CASIO GC jack.

  4. Make sure both cable plugs are firmly inserted into the calculator and CLAB jacks.

  5. Press the CLAB power button to turn it on.

  6. The LED on the left half of the CLAB power button flashes red, a beep sounds, and the LED lights green when the unit becomes ready for use.

    When communication between the calculator and CLAB is established, the top screen shows the input status from CLAB. The screen to the right shows that nothing is connected to CLAB sensor terminals 1, 2, or 3 (corresponding to CH1, CH2, CH3) and that there is no input from CLAB.

    CY876_V2.1_E-CON5 _Operation Flow_2
  7. Connect the temperature sensor included with CLAB to CLAB sensor terminal 1.

  8. The connected sensor is recognized automatically, and the measurement value from the temperature sensor appears in the CH1 row.

    Use d to highlight the CH1 row. This causes the sensor name to appear in the status bar.

    CY876_V2.1_E-CON5 _Operation Flow_3

Note

You can perform steps 1 through 3 above in any order. If “CLAB disconnected” appears on the calculator even after you complete all steps, there is a problem with communication between the calculator and CLAB. In this case, check again to make sure the two ends of the cable are firmly inserted into the calculator and CLAB jacks. When the connection is correct, the screen appears as shown in step 3 above.

The E-CON5 app supports sensors from CMA and Vernier. However, some sensors may not be recognized automatically when connected to CLAB. To use a sensor that is not recognized automatically, select it from the library or create a custom sensor. For details, see the information at the following locations.

To measure using CLAB’s built-in accelerometer, you must use the E-CON5 app to enable the accelerometer. For details, see Using the Acceleration Sensor.

E-CON5 App Tabs

The E-CON5 app has two tabs: the Preparation tab and the Analysis tab.

CY876_V2.1_E-CON5 _Tab configuration_1-1

The following describes each item on the Measurement Method screen.

CLAB Operating Modes

CLAB has the following two operating modes.

Connected Mode

This is the operating mode when you select CLAB: Connected on the Measurement Method screen. Connected mode is the initial default setting for the E-CON5 app.

In Connected mode, measurement is performed while the calculator and CLAB remain connected. During measurement, CLAB is controlled by the E-CON5 app. This mode provides three measurement types: Time-based, Manual, and Interval. For details, see Measurement Types. When using the Time-based type with a relatively low sampling frequency, or when using the Manual type or Interval type, the E-CON5 app shows measurement data in real time so you can observe progress during measurement.

In this mode, measurement data is saved in the calculator’s memory* and not in CLAB’s memory.

Standalone Mode

This is the operating mode when you select CLAB: Standalone on the Measurement Method screen.

In Standalone mode, you first upload the measurement setup from the calculator’s E-CON5 app to CLAB. Before starting measurement, disconnect the cable between the calculator and CLAB, and then perform measurement using CLAB alone.

This method is convenient, for example, when you want to collect data outdoors over an extended period.
In this mode, measurement data is saved temporarily in CLAB’s memory. After measurement is complete, you can download the data from CLAB to the calculator’s memory.*

For details, see E-CON5 App Data Storage.

Measurement Types

CLAB has three measurement types.

Time-based Type

This is the measurement type when you select Type: Time-based on the Measurement Method screen.

With this type, measurement data from sensors is collected for a specified length of time at a specified sampling frequency. Measurement ends automatically when the specified time elapses.

For details about the setting items when this type is selected, see Time-based Type Setting Items.

Manual Type

This is the measurement type when you select Type: Manual on the Measurement Method screen. This type is available only in Connected mode.

With this type, you specify in advance the number of times (number of samples) that data will be measured. After measurement starts, measurement data from the sensors is collected each time you press O. In addition to sensor measurement data, you can also collect data entered manually at the same time. For example, you can use this function to verify Boyle’s law in an experiment: measuring gas pressure using a pressure sensor and manually entering the corresponding volume value measured separately. Measurement ends when the specified number of samples has been collected.

For details about the setting items when this type is selected, see Manual Type Setting Items.

Interval Type

This is the measurement type when you select Type: Interval on the Measurement Method screen. This type is available only in Connected mode.

With this type, the measurement data collected is the time interval between two points at which the measurement value from the specified channel (CH1, CH2, or CH3) crosses a specified threshold value (exceeds it [Rise] or falls below it [Fall]).

For example, with the initial default Rise-Rise setting, the time interval indicated by in the figure below is collected as measurement data.

 

CY876_V2.1_E-CON5 _Measurement Type-Interval_1
  1. Measurement value from sensor

  2. Threshold value

  3. Time interval

 

For details about the setting items when this type is selected, see Interval Type Setting Items.

Time-based Type Setting Items

The items and their functions when you select Type: Time-based on the Measurement Method screen are described below.

In the explanations, options and values marked with “” are initial defaults.

Unit

Specifies the unit for Duration and Frequency. Available options:

Duration unit: msec (milliseconds), sec (seconds), min (minutes), hour (hours)

Frequency unit: /msec (per a millisecond), /sec (per a second), /min (per a minute), /hour (per an hour)

If you change the Unit setting of either the Duration or the Frequency item, the value of that item is recalculated according to the new unit. For example, if Duration is currently 10 (sec) and you change the Unit from sec to msec, the Duration value becomes 10,000 (msec).

Duration

Specifies the measurement time (Initial Default: 10 seconds). If you change the Duration value, the Samples value is automatically adjusted according to the current Frequency value and the new Duration value.

Frequency

Specifies the sampling frequency, which is the number of measurements per unit of time (Initial Default: Once/second). If you change the Frequency value, the Samples value is automatically adjusted according to the current Duration value and the new Frequency value.

Samples

Specifies the number of samples, which is the number of measurements within the entire measurement time (Initial Default: 11). If you change the Samples value, the Duration value is automatically adjusted according to the current Frequency value and the new Samples value.

Trigger

Specifies the measurement start condition. The available options depend on the operating mode.

 

CLAB in Connected mode

None: Measurement starts when you select Start Measurement (button or menu) with the E-CON5 app.

CH1, CH2, CH3: Measurement starts when the measured value from the selected channel (CH1, CH2, or CH3) goes above or below a specified value.

Using Ball Bounce (Analysis Tab)

Prepare an experiment setup like the one shown to the right, in which a ball is dropped, lands on the floor, and bounces back. You can analyze measurement results with the Ball Bounce function of the E-CON5 app. A motion sensor (BT55i by CMA) is used for measurement.

 

The motion sensor measures the distance from the sensor to the object. With this experiment, hold the ball by hand directly under the motion sensor, and, as soon as measurement starts, release the ball to let it fall vertically. Elapsed time from the start of measurement (t(s)) and the distance to the ball at each elapsed time (x(m)) are collected as measurement data.

 

Based on this measurement data, the Ball Bounce function performs the following processes:

Automatic calculation of the distance from the floor, velocity, and acceleration of the ball at each elapsed time, and output to list variables.

Measuring in Connected Mode Using Interval Type

Important!

When measuring with the Interval type, you can use only one sensor as the signal source for time-interval measurement. Generally speaking, be sure to use an analog-range sensor, and do not use a counter-range sensor.

As exceptions to the above, CMA photogates (BT63i, 0663i) and CMA radiation sensors (0666i, BT70i) can be used as signal sources for time-interval measurement. When these sensors are connected to CLAB and auto-recognized, their counter range is shown in the sensor details dialog. However, for time-interval measurement, the analog range of 0 to 5 V and a threshold of 2.5 V are applied.

Appendix

E-CON5 App Limitations

The maximum values for measurement time, sampling frequency, and number of samples that can be specified with the E-CON5 app are shown in the following table.

Setting Item

Upper Specification Limit

Duration (measurement time)

162,000 seconds (45 hours)

Frequency (sampling frequency)

1 sensor: 100,000/s

2 sensors: 50,000/s

3 sensors: 15,000/s

1 BT55i sensor: 100/s

2 BT55i sensors: 20/s

3 BT55i sensors: 5/s

Sensor with count function: 2,500/s

Pitch sensor: 100/s

CLAB built-in accelerometer: 800/s

Samples (number of samples)

30,000

The upper limits above are the possible values for each individual setting item. Based on the values specified for two of the three items, the remaining setting value is adjusted. For example, when measuring with one sensor, if you specify the maximum sampling frequency (100,000/s) and the maximum number of samples (30,000), the measurement time is automatically set to 0.3 seconds (30,000 ÷ 100,000). (On the Measurement Method screen, the actual display will be 0.2999 s.)

 

Also, if the setup of the sensor at the time measurement is started differs from the setting values currently configured on the Measurement Method screen, a warning dialog will appear and the setting values will be adjusted automatically.

Example: When only a voltage sensor is connected, the sampling frequency is set to 1,000/s, and then the built-in accelerometer of CLAB is enabled before starting measurement. In this case, since the maximum sampling frequency that can be specified for the built-in accelerometer is 800/s, a warning dialog like the one shown here will appear.

CY876_V2.1_E-CON5 _Restrictions on E-CON5 app_1

If you select [OK], the sampling frequency is automatically adjusted (in this case changed to 800/s), and measurement starts.

Important!

Continuous measurement performed for an extended period may cause the battery to run out more quickly than usual.

When performing long-term measurement, keep an eye on the remaining battery power of the calculator. If the remaining battery power is insufficient, the battery may run out before the specified measurement time elapses, causing the calculator to turn off automatically and the measurement to be interrupted.

Real-time Display of Measurement Data During Measurement

Whenever possible, the E-CON5 app displays measurement data in real time as a graph during measurement execution.

The following are guidelines for when graphs can be displayed in real time.

Measuring with one sensor: Sampling frequency setting* within 400/s

Measuring with two sensors: Sampling frequency setting* within 200/s

Measuring with three sensors: Sampling frequency setting* within 100/s

Frequency setting of the Measurement Method screen

If the E-CON5 app cannot display measurement data in real time as a graph, the following screen appears when measurement starts.

CY876_V2.1_E-CON5 _Displaying measurement data in real time_1

In this case, the graph screen based on the measured values will be displayed after measurement is complete.

E-CON5 App Data Storage

Various types of E-CON5 app data (such as setup data and measurement results) are stored in the calculator’s main memory and storage memory. For details about main memory and storage memory, see Memory App.

Main Memory

Within the E-CON5 group in the calculator’s main memory, the information configured with the Measurement Method screen and the latest measurement data are stored. The names and content of the data saved in the E-CON5 group are shown in the following table.

Data Name

Contents

g4m Channel1, Channel2, Channel3

Data of sensors automatically recognized (or manually assigned) on channels CH1, CH2, and CH3.

g4m ChannelX, ChannelY, ChannelZ
