    Acceleration.
    Frequency, that's slightly troublesome, click meas. and press reset.
    Pulse, T½ Counting
    Read memory, up to 999 measurements
    Reset memory

    Be aware that the device is semiautomatic, that is, you must press the reset button on the device in order to send the measurement to the PC.

    Notice that the cable is crossed as with the Digital Meter.

    Baud rate 9600, no parity, 1 stop, 8 data bits. Command "V" for version.

    It is possible to set the baud rate to 9600, see the 2001 timer - scaler and interface manual.

    The Electronic Counter model 2002 has been specifically designed for educational use.


    Digital Meter

    Menu in Datalyse:

    Graphical measurement

    Multimeter, thermometer and pHmeter all in one device. Minimum time is 0.5 second. You setup using the device buttons, Datalyse reads this setup and adapts the coordinate system.

    Notice that the cable is crossed:

    2 to 3 and 3 to 2 (data)
    5 to 20 and 20 to 5 (control).

    Baud rate 300, (1200), no parity, 1 stop, 8 data bits. Has no version command. Default baud rate is 300, but Datalyse sets it to 1200.


    Digital demonstration multimeter, version 1.20

    Menu in Datalyse

    Graphical measurement of a value.
    Multitable of from 1 to 4 values.

    The demonstration multimeter can measure current, voltage, resistance, frequency, temperature, pH and pressure.
    There are four galvanically separated parts in the DMI4. This feature makes it possible to leave measurement probes connected while measuring something else. And it is possible to measure temperature, pH and pressure and Voltage/current/resistance/frequency at the same time when the device is connected to a computer.

    The 4 sections are as follows:

    1. Temperature
    2. pH
    3. Pressure
    4. Volt, current, resistance and frequency

    With Graphical measurement turn the central knob to the wanted function.

    With measurements in Multitable turn the central knob to Volt, current, resistance or frequency if yo want to measure one of these quantities.

    Baud rate 9600, no parity, 1 stop, 8 data bits. Command "V" for version.


    Function Generator, version 1.21

    Menu in Datalyse

    Graphical measurement of frequencies.
    Setup: Control panel for control of all functions.

    Baud rate 1200, no parity, 1 stop, 8 data bits. Command "V" for version.

    Control panel menu:

    Setup:

    You can control the overtones of a standing cord. Enter the frequency and press »Overtones«. The device will be set to 1st overtone, 2nd overtone...9th overtone and again the base tone. Be aware that setting the Function Generator to a certain frequency is much easier (faster) with the control panel than the buttons on front of the device.

    Guess a note:

    Random provides you with a tone. Try guessing the frequency; press Answer to see the proper answer.

    Sweep:

    The Function Generator does not have a hardware sweep but you can make a sweep with Datalyse. The parameters are set here and the sweep is started from the main menu under »Start sweep«. Datalyse sends a frequency command to the device every time a time step has passed (minimum: 0,05s, maximum: 5,0 s). Before starting you have to set the function generator to Amplifier and an appropriate volume. If the pc has a soundcard the checkbox »Measure sound« will be active. This means that you can measure a sound signal as a function of frequency. E.g. you can show resonance in a cardboard tube.

    The pc's microphone has an interval of 16 bits [-32767; 32768]. While measuring Datalyse finds the minimum and the maximum of the microphone signal and calculates the amplitude in %.


    Geiger-Müller Counter 5136.00, version 1.0. New Device, April 2011!

    Menu in Datalyse

    Half-thickness, slab thickness is entered before each measurement.
    Half-life (and other time-dependent measurements).
    Poisson distribution, a set time of 1 second.

    Baud rate 9600, no parity, 1 stop, 8 data bits. Command "V" for version.


    G-M Counter with datalog, version 1.0

    Menu in Datalyse

    Half-thickness, slab thickness is entered before each measurement.
    Half-life (and other time-dependent measurements).
    Poisson distribution, a set time of 1 second.
    Read memory, max 50 measurements.
    Read datalog, max 250 measurements.

    Baud rate 1200 (9600), no parity, 1 stop, 8 data bits. Command "V" for version.

    The 9600 in brackets means that Datalyse sets this baud rate at startup. Otherwise, log reading would be too slow, now it takes about 20 seconds.


    Watt- and energy Meter

    Menu in Datalyse

    Graphical measurement
    Multitable, all parameters are measured and written to the table.
    Summary; here, measurements are not saved.
    Setup the log, setup of all parameters.
    Reading the log.

    The log is placed in the table. Graphs can be made later on.

    Baud rate 1200 (9600), no parity, 1 stop, 8 data bits. Command "V" for version.

    The 9600 in brackets means that the rate is changed while reading the log. Otherwise, reading the log would take too long, now it takes about 30 seconds.

    Setup log:

    Start condition:

    1: manual
    2: clock
    3: power level

    The log is started manually by simultaneously pressing FUNCTION and RESET/SELECT buttons on the Energy Meter. If you choose clock, you do not have to specify a power level. If you choose power level, there is no need to specify a starting time.

    Log layout:

    1: automatic compression
    2: preset time

    The log may hold 250 measurements.

    Automatic compression means that every second measurement will be deleted when the log is full, making room for more measurements. If you choose preset time, the time between each measurement is calculated from the total logging time. Logging ends when the datalog is full.

    During the log setup, the log will be readied for measuring. The datalog will not be deleted until the log is activated.
