1.4 Using the Mini
Before using the Mini for the first time, the unit should be charged for
six hours using the USB cord. This cord can be plugged into any
computer or standard wall socket. While charging, the LED lights will
blink red. When the Mini is fully charged, the LED lights will change to
green.
The center blue button controls many of the Mini’s functions.

1.5 Configuration of the Mini
All Mini configurations are performed from the GlobiLab software
menu. Your Mini must be paired with the computer or tablet that you
plan to use with it. See Chapter 3.0 below for instructions on how to
pair the Mini with your computer/tablet.

2.0 GlobiLab Software
2.1 Software Installation
You can also download the software from the Globisens website at
http://www.globisens.net/support#2. Simple instructions will take
you through the installation of the GlobiLab software.
2.2 Software Functions
A quick overview of the major features of the GlobiLab software is
below. For more detailed instructions on how to use the GlobiLab
software please read the Getting to Know the Mini document in the
Getting Started section of our website.

2.3 Software Icons and their Functions
Selecting the Open-project icon opens the stored activity
*.XML files and displays all its graphs and graphical
attributes.
Selecting the Workbook icon opens the activities folder,
where users can choose from a variety of PDF activities.
Clicking the Display-options small triangle icon allows the
user to select one of the following six display options:
Meter View
Table View
Graph View
Map View
Mixed Meter & Graph View
Mixed Table & Graph View
Sensor legend:
1. A left click on the sensor name makes it active and
changes the y-axis to this sensor’s units/scale.
2. A single right click on the sensor name changes a line
graph to individual data points
3. A second right click on the sensor name removes this
sensor graph from the display
4. A third right click on the sensor name returns to a line
graph on the display
The default graph title is New Experiment. Changing this
title is done with a double left mouse click over the title. A
small text dialog box will open where the new title can be
entered.
When displaying two or more sensors –a right click on the
graph x-axis title will open a dialog box to assign either a
sensor or time as the x-axis.

8
Meter View
A left mouse click on the four bottom blue dot icons will
change the number of meters on the screen to: 1, 2, 4 or 6
meters. A left click on any of the meters will open a dialog
box for meter type selection and assigning a sensor for this
meter.
Marker
A left mouse click, near any of the graphs, will place a
marker on the graph. Hovering over any of the markers,
while pressing and holding the left mouse button and
dragging the mouse, will move the marker over the graph
and will show the values as the marker moves along the
graph line. Selecting the Marker icon again, exits the
Marker mode.
Annotation
Allows a left mouse click to open a dialog box where text
and images can be entered. Pressing the Annotation icon
again exits the Annotation mode.
Mathematical
Functions
Pressing the Function-options small triangle icon allows the
user to apply the mathematical functions listed below
between the graph markers:
Linear regression will display the best linear line that
fits the graph between the locations of two markers. Next to
the line the software will open a small text box displaying
the linear line equation: Y= aX+b.
Quadric regression will display the best parabolic line
(2nd degree) that fits the graph between the locations of
two markers. Next to the line the software will open a small
text box displaying the parabolic line equation: Y= aX²+bX+c.
FFT is used to split the graphic display to show the
original measurements in a time scale in the top window
and to show its harmonics, on a frequency scale in the lower
window.
Smooth is used to average a graph. Every sample is
an average of the two readings before and two after
samples. It can be useful in case the graph is very noisy.
Derivative measures the sensitivity to change of a
quantity in one data source determined by another quantity
or another data source.

9
Run/Stop
Starts or stops a data collection.
Creates an overlay with a second data collection over the
original graph for comparison.
Selective download opens a table listing all stored
recordings. Selecting one of the lines on the table and
pressing download will download this specific recording to
the computer.
Setup icon opens a dialog box, where users can
select/remove sensors, set the sampling rate and the
amount of samples for the next data recording.
EXCEL icon saves the file in a *.CSV format, prompts the
user for a file name and then automatically opens EXCEL and
exports the experiment data into the spreadsheet.
GlobiLab status bar at the bottom right corner of the
software includes 3 icons:
1. USB indicator –the USB Indicator is always grayed out
because the Mini offers no USB communication.
2. Bluetooth indicator –when blue indicates a Bluetooth
wireless communication between the computer and
the Mini. A right mouse click on this icon will open a
list of recognized Mini’s. Click on one to connect.
3. Memory info –shows how many experiments are
stored in the Mini’s memory, out of a maximum of
127. In the example above there are 7 stored
experiments out of 127. A right mouse click on this
section will allow users to erase all stored data or just
the last recording.

3.0 Mini –GlobiLab Communication
3.1 USB Connection
Unlike the Labdisc, the Mini does not communicate data to the
computer/tablet via the USB cable. With the Mini, the USB cable is
strictly for charging purposes.
3.2 Bluetooth Wireless Communication
Before communicating wirelessly with a Mini for the first time, the
Mini should be added as a device to the computer in a process called
pairing. Pairing only needs to be performed once for any Mini. After
pairing is complete the computer stores the connection information,
including a unique number for each Mini (found on a small silver
sticker on the back of your Mini).
3.2.1 Set the Mini to Pairing Mode
1. Turn on the Mini by pressing the center blue button.
2. Press and hold the center blue button until the LED lights all flash
red. Your Mini is ready for pairing.
3.2.2 Pairing the Mini with a Windows PC
1. Start the GlobiLab software.
2. Right click the Bluetooth icon located in the bottom
right corner of the screen.
3. This opens up a pop-up menu with a list of Mini devices that may
already be paired with this computer. At the bottom of the list
select “Find More Labdiscs & Sensors.”

18
4. The computer opens the “Add a device” dialog box and searches
for nearby Bluetooth devices.
5. Your Mini will be displayed as MiniDisc_xxxx where xxxx is the 4
last digits of the Mini serial number sticker. Select this device and
press next.
6. Enter 1234 as the PIN. Press and hold the blue center button on
the Mini until the LED lights flash red and then press “Ok” on the
PC.
7. The computer will indicate that the pairing is successful and load
the driver needed for the Mini. Loading the driver may take
several minutes.
8. To connect to the Mini, right click on the Bluetooth icon
in the GlobiLab status bar, located at the bottom right corner of
the screen and select the device you want from the pop-up menu
listing the paired devices. When connected, the Bluetooth icon
will turn blue and a notice in the lower left hand corner of the
screen will indicate that you are connected to MiniDisc_xxxx.
3.2.3 Pairing the Mini with a Mac OS
1. Open the Bluetooth menu from the Mac menu bar and select “Set
up Bluetooth Device.”
2. Your Mini will be displayed as MiniDisc_xxxx in the dialog box that
opens. xxxx is the last four digits of the Mini serial number.
3. In the next dialog box, press “Passcode Options” and select “Use a
Specific Passcode.” Enter 1234 as the passcode.
4. Press and hold the blue center button on the Mini until the LED
lights flash red. Press “Ok” and “Continue” on the Mac computer.
5. When the wizard action is complete, the computer will confirm
that the Mini has successfully been paired to the Mac.
