CLAB

Item: 003

CLAB is an easy-to-use, powerful and inexpensive data collection system that works with CASIO Graphic Calculators, with computers and standalone. CLAB is equipped with its own processor and memory, enabling measurements at sampling rates up to 100000 Hz. For connecting sensors CLAB has three analog BT sensor inputs. Additionally it has a built-in 3-axis accelerometer.

Using CLAB with a CASIO Graphic calculator
CLAB can be used with CASIO Graphic Calculators such as CASIO fx-CG Series, fx-9860GII Series or ClassPad II (fx-CP400). When connected to a such calculator CLAB is controlled by the E-CON software running on the calculator. E-CON is a menu-driven calculator application developed by CASIO. It allows configuring experiments with CLAB, collecting the data via connected sensors, graphing and processing the collected data. To connect CLAB to a CASIO Graphic Calculator you need a data communication cable with 3-pin jack connectors (SB-62). This cable is provided with your CASIO Graphic Calculator.

Using CLAB with a Computer
Via the provided USB cable CLAB can be connected to a USB port of a computer and work as a lab interface. The Coach 7 or Coach 7 Lite software running on the PC controls CLAB. The collected data are transferred to the computer, the measurement can be followed on the computer screen and the collected data can be analyzed in Coach.

Using CLAB standalone
When using CLAB as a standalone device, CLAB controls the data collection process; it collects and stores the measurement data. This is very useful for remote data collection e.g. outside the school. The experimental setup is prepared using the E-CON application on a CASIO Graphic Calculator or the Coach software on a computer and uploaded to CLAB. The measured data are stored in the CLAB memory and can be downloaded into a calculator or a computer after the measurement is finished.

Sensors for CLAB
For connecting sensors CLAB has three analog BT (right-handed) sensor inputs. These inputs support all analog CMA sensors and automatically identify these sensors. Especially for CLAB a new CMA Ultrasonic Motion Detector (BT55i), which can be connected to analog BT inputs of CLAB, is available.

Accelerometer -25..25 g

Item: BT11i

The High g Accelerometer BT11i measures acceleration in the range between -25.0 g (-245.0 m/s2) and 25.0 g (245.0 m/s2). The sensing element of the sensor is mounted inside the round box and the arrow on the label of this box marks the direction in which acceleration is measured. The measurement range of the High g Accelerometer allows measuring accelerations produced during collision experiments but dropping the Accelerometer on a hard surface from even a few centimeters can produce acceleration of a hundred g’s. Accelerations above ± 50 g will damage the sensor.

The High g Accelerometer is delivered with two pieces of Velcro tape, which can be used to mount the round box of the Accelerometer on a moving object.

The Accelerometer can be used for a wide variety of experiments, both inside and outside the classroom. The Accelerometer should be mounted in the appropriate orientation for an experiment (so that its axis is in the direction of interest).

  • Measuring acceleration during a collision.
  • Measuring acceleration as it moves in a horizontal circle and/or vertical circle.
  • Measuring accelerations during body movements: put the Accelerometer under your belt buckle, and jump up and down, land both with your knees flexed and with your knees held more stiff.
  • If you have the CMA VinciLab data-logger you might measure acceleration on elevators, on amusement park rides, on playground apparatus, in a car, during bungee jumps, etc.
  • To measure acceleration in two or three directions mount two or three Accelerometers at right directions.

DO NOT drop the sensor directly onto a solid surface this will damage the sensor.

The High g Accelerometer can be directly connected to analog BT inputs of the CMA interfaces.

Attention: The sensor cable BT - IEEE1394 needed to connect the sensor to an interface is not supplied with the sensor and has to be purchased separately (CMA Art. Nr BTsc_1).

Resonance Set

Item: 060

The Resonance Kit 060 can be used to introduce some of the basics of oscillation, resonance, electromagnetic induction, and spring constants to the students. The kit consists of the following parts:

  • Ground plate, including 4 thumb screws
  • Long metal bar
  • Short metal bar with a mounting hole and thumb screw (attached to the long metal bar)
  • Plastic cylinder, including 1 Philips head screw inserted in the bottom plate
  • Coil with a mounting hole and thumb screw
  • Magnet holder, with a small screw inserted
  • 2x Magnet
  • Spring
  • Spring holder with two small thumb screws on the sides and one small screw in the middle.

The set can be used in various ways for measurement and control. The coil can be used as an actuator: by using one of the CoachLab I/II/II+ outputs to drive current through the coil, the coil can exert a force on the magnets that are attached to the spring. The coil can also be used as a sensor: when the magnets that are mounted to the spring move through the coil, they create a changing magnetic field, and through electromagnetic induction, a voltage will be induced over the coil that can be measured directly or through a voltage sensor.

All functions of the set can be used in combination with the CoachLab II/II+ interface. It is also possible to use the set with €Lab and VinciLab, but because these interfaces do not have control outputs the set can be used only for measurement with sensors. For the use of the coil as a sensor the 0519 adapter is needed. For measuring forces a Force senso, such as CMA 0663i or BT42i Force sensor is needed.

System Board

Item: 0020

The System Board is designed for logic, measurement, control and automation practicals. Students use the System Board to design and test their self-built automated systems. They get acquainted with digitizing analog signals, processing digital signals and using signals to control actuators. The System Board is powered via an external AC power adapter (230V/9V) which is delivered together with the board.

The elements of the System Board are grouped into three sections:

  • The Input section (‘Invoer’) is the subsystem which gathers data from the environment and conditions the signal S1 (which carries the data) to make it suitable for processing. The input section consists of two general sensor inputs, a sound sensor, two push buttons, a variable voltage, a pulse generator and an AD-converter..
  • The Processing section (‘Verwerking’) is the subsystem which processes the signal S2 to achieve a specific system goal. This section consists of two comparators for processing analog signals and for processing digital signals, two AND ports, an OFF port, two invertors, a memory cell and a pulse counter..
  • The Output section (‘Uitvoer’) is the subsystem which presents the processed data S3 in a useful form for the user or which carries out an action based on the signals. This section consists of four LEDs, a buzzer and relay.

Please note that Temperaturesensor 0511 cannot be connected to the System Board.
