CLAB
STANDALONE
When using
C
LAB as a standalone device,
C
LAB 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
C
LAB.
C
LAB can be then disconnected from the calculator or computer.
The Power button of
C
LAB is used to start and stop the pre-defined experiment
and LEDs and a speaker give feedback about the status of the data collection. The
measured data are stored in the
C
LAB memory and can be downloaded into a
calculator or a computer after the measurement is finished. Using E-CON or
Coach the collected data can be further analyzed and processed.
1. Typical measurement procedure with CLAB standalone
•
Prepare the experiment setting by using a CASIO Graphical Calculator with the
E-CON program or a computer with the Coach program.
•
Send the experiment settings to
C
LAB. The right Measurement LED of
C
LAB
becomes blue when CLAB is ready.
•
Now you can disconnect
C
LAB from your calculator or computer. If you wish
(long time between preparation of the measurement and the start of the
measurement) you can now turn your
C
LAB off. Settings are stored in
permanent memory. After you turn CLAB on again the right measurement LED
will show CLAB is ready for measurement.
•
Start the measurement by pressing the Power Button.
o
If
Triggering
is enabled (the right Measurement LED is blinking blue) then
the measurement is started automatically when the trigger conditions are
met. To force triggering manually, press the Power Button.
o
When the type of measurement is set to
Manual
then press the Power
Button to collect a single measurement.
•
The right Measurement LED blinks green when CLAB is collecting data. If you
want to stop the measurement, click the Power Button.
•
For long-time measurements:
o
with time measurements longer than 2 hours, and
o
with sampling frequency of one sample per 2 minutes (or lower), and
o
without use of Motion detectors BT55i,
C
LAB is set into a Power-save Mode and will turn itself off between collecting
single data samples. It awakes 2 seconds before a new sample has to be
collected. Data are saved in
C
LAB memory in between. During the
measurement a short press of the Power Button will wake CLAB up. It will stay
awake until the next sample is taken and then go back to sleep again.
