Fourier Multi Log Pro User manual

Getting started with MultiLogPRO
Before you first use MultiLogPRO, charge the unit for 10 to 12
hours when turned off.
1. Press the On button
2. Plug in the sensors
Start with the first input on the right. If MultiLogPRO is in
Auto ID mode (the default mode – for more details see section
1.2.9 ‘Configure your MultiLogPRO’ in the user guide) it will
display the setup menu and will identify the sensors you’ve
plugged in.
NOTE: Sensors must be added successively, starting with input-
1. If a single sensor is used it must be connected to I/O-1. If two
sensors are used in an experiment, they must be connected to
I/O-1 and I/O-2.
The arrow indicates that MultiLogPRO is ready to accept a
new sampling rate.
If the MultiLogPRO is in 8 inputs mode you have to select the
sensors manually.
3. Select Rate Use the Forward and
Backward arrow buttons
to select the desired rate, then
press the Enter button.
MultiLogPRO automatically
moves to the next step in the setup process and the arrow
now points to the “samples” row.
4. Select total number of samples
Use the Forward and
Backward arrow buttons
to select the desired number
of samples, then press the
Enter button.
5. Choose display
Use the Forward and
Backward arrow buttons
to select the desired display,
then press the Enter
button.
6. Start recording
Press the Forward arrow
button to start recording.
Or press the Enter button
if you want to go back to the
first item (Rate).
You can stop recording any time by pressing the Escape
button.
7. The Cursor Use the Cursor (dotted vertical
line) in Graphic Display mode
to read data values or
to zoom in to the area around
a selected point. The cursor is
displayed automatically after logging has ended.
Use the Forward and Backward arrow buttons to move the
cursor
Zooming: Position the cursor in the area you want to zoom
into.
Press the Forward and Backward arrow buttons
simultaneously. You will zoom in around the cursor in a 2:1
ratio. Press the Forward and Backward arrow buttons again
to zoom in further.
Press the Escape button to zoom out.
8. Download data
To download data that was recorded while MultiLogPRO
was not connected to a computer, connect
MultiLogPRO to the computer with the serial or
USB cable, run the MultiLab program and click>>

>> Download on the toolbar. Once the transfer is
complete, the data will be displayed automatically in the graph
window and in the table window. If there are several
experiments stored in the MultiLogPRO, the first download
will bring up the most recent experiment; the second download
will bring up the earliest file, the third download will bring up
the second earliest file, and so on.
To download a particular experiment, choose Selective
Download from the Logger menu, then select the
experiment’s number in the Download dialog box.
Getting started with MultiLab
1. Prepare MultiLogPRO
1) Connect MultiLogPRO to the PC
2) Turn on MultiLogPRO
3) Plug in any sensors
4) Open the MultiLab software
2. Setup the MultiLogPRO Use the Setup
wizard to guide you
through the setup
process
1) Click Setup
wizard on
the main tool-
bar to open the
setup wizard
The first step is to assign sensors to each input. If you are
working with MultiLogPRO in Auto ID mode, the sensors
are selected automatically when plugged into MultiLogPRO.
Otherwise, you can manually select the sensors you are
using from the corresponding input drop lists.
2) Click Next to move to the second step
3) Select the
desired
recording rate
in the Select
rate drop list
4) Click Next to
move to the
third step
5) Select the
desired length
of the recording
period in the
Select
recording
time drop list.
6) Click Finish to
complete the setup and to send the
setup command to the
MultiLogPRO.
3. Start Recording
Click Run on the toolbar to start
recording.
If the recording rate is 100
measurements per second or less,
MultiLab automatically opens a graph
window displaying the data in real time,
plotting it on the graph as it is being
recorded. If the recording rate is higher
than 100/s, the data will be
downloaded and displayed
automatically once the data recording
is finished.
You can stop recording anytime by clicking Stop on the
toolbar.
4. Analyze the data
Use the first cursor to display individual data recording values,
to select a curve or to reveal the hidden Y-axis.
Use two cursors to display the difference between two
coordinate values or to select a range of data points.
To display the first cursor: Double click on an individual
data point or click 1st Cursor on the lower
toolbar to display the cursor. You can click and

drag the cursor with the mouse onto any other point on the
plot, or onto a different plot (to move the cursor, click on the
very tip of the cursor arrow). For finer cursor movements use
the forward and backward keys on the keyboard.
The coordinate values of the selected point will appear in the
information bar at the bottom of the graph window.
To display the second cursor: Double click again anywhere
on the graph area or click 2nd Cursor on the graph
toolbar.
The information bar will now display the difference between
the two coordinate values. If the x-axis is time 1/dt will also
be displayed.
To apply linear curve fit: Use the cursors to select a range on
the graph, then click Linear Fit on the main toolbar
To take a derivative of a plot: Use the cursors to select a range
on the graph, then click Derivative on the main toolbar
NOTE: To apply more advanced analysis tools go to the Analysis
menu or open the Analysis Wizard
See the User Guide for full details on the use of MultiLogPRO
and MultiLab software
The Workbook
The Workbook is an online library of experiment manuals called
worksheets, that appear in the format of a Web page. Each
worksheet includes an experiment template that automatically
configures both MultiLab and MultiLogPRO at the push of a
button. To begin recording, all you need to do is click Run.
Every time you run an experiment from a worksheet, MultiLab
opens a new project file with the same predefined setup.
1. Click Workbook on the menu bar, and then click Open
worksheet.
2. Double click the file name to open the worksheet. Follow the
on-screen instructions and use the scroll bar, hyperlinks and
the Back and Forward buttons to navigate throughout the
document.
3. Click Launch to configure MultiLab and MultiLogPRO Click
Close to return to MultiLab.
You are now ready to start the experiment, click Run on the
main toolbar to begin recording
