1.4 Using the Labdisc
CHARGE THE LABDISC BATTERY BEFORE STARTING
Before working with the Labdisc for the first time, the unit should be charged for
six hours with the supplied 12 V charger. The Labdisc charging input is located to
the left of the On/Off key. Simply rotate the orange ring until the charging input on
the Labdisc is exposed and then connect the
charger plug to the charging input.
The Labdisc charger will accept any input voltage ranging from 100 to
240 VAC 50/60 Hz, making it functional worldwide.

2.4 GlobiLab Software for iPad
The GlobiLab software for iPad (iPad, iPad 2 and 3rd generation iPad models) is
available in the App Store and makes K-12 science experiments mobile, convenient
and immediate. GlobiLab wirelessly integrates between the Labdisc data logger and
the iPad. Allowing full Labdisc management (setup of all data logging parameters,
online display of current measurements and download of the Labdisc sample
memory), together with graph manipulations (markers, zoom, crop, text and image
annotation) and data analysis (statistics and curve fitting etc.).
GlobiLab software for iPad was specifically designed to engage students and help
visualize complex science concepts by harnessing the iPad built-in accelerometer
sensor, data display, multimedia and multi-touch features. The following steps
provide a guide on the installation and implementation of the GlobiLab App for iPad.

3 Labdisc – GlobiLab Communication
3.1 USB Communication
Upon USB cable connection between the computer and the Labdisc, the GlobiLab
software automatically detects the USB connection and begins communicating with
the Labdisc.
3.2 Bluetooth Wireless Communication
Before wireless communication with a Labdisc for the first time, the Labdisc should
be added as a device to the computer in a process called pairing. Pairing need be
done only once for each Labdisc, after which the computer stores the connection
information, including a unique name for each Labdisc. When no Labdisc is
connected via USB, the computer will automatically try to wirelessly connect to the
last connected Labdisc. To connect to a different or a new Labdisc, right click on
the Bluetooth icon in the GlobiLab status bar, located at the
bottom right corner of the screen, then click on the Labdisc you want to connect
to.
3.2.1 Set the Labdisc to “pairing mode”
1. Turn on the Labdisc.
2. Press the Scroll key to launch the Labdisc menu.
3. Scroll and select the Configuration menu.
4. In the configuration menu scroll and select the Bluetooth icon.
5. In the Bluetooth menu select “BT pairing”. The Labdisc will produce a
long “beep” sound and switch to “BT enabled”.
