Download Labdisc stored measurements to the tablet
The
Labdisc
can store up to 127 different experiments.
This is very useful when conducting outdoor data
collection or long measurements.
Tap the Download icon
The application will list all
Labdisc
stored
experiments. Each line on this list shows what
sensors were recorded, at what sampling rate and
for how many samples. In addition it indicates the
date and time of the recording.
Click on one of the lines in the list. The
Labdisc
transfers the data to the tablet.
After all the data is transferred, GlobiLab will show
a graph of the collected measurement
Data analysis (markers, curve fitting)
Tap the open icon
and select “Free Fall”.
This graph describes a real recording of a ping-
pong ball bouncing on a table, as recorded by the
Labdisc
distance sensor. For more details see the
Free Fall movie at:

Long touch on the graph to add a marker
Touch the marker to cross and drag it with your
finger. View the marker text box data changing
while the marker follows the graph line.
Tap the graph legend and select “Dots” to view
the actual sampling points
Long touch the graph to add a second marker
Place both the markers at the beginning and end
of a single ball jump
Tap the Curve Fitting icon
, select a Quadric
Regression to get the mathematical equation
representing the ping-pong ball jump. From this
equation we can calculate earth’s gravitation.
