Introduction
The MultiLogPRO is a powerful standalone 12-bit data
logger with a clear LCD graphic display and a 128K internal
memory. Recorded data is displayed in the form of graphs,
tables, meters or digital displays, and can be analyzed with a
number of pre-programmed analysis functions.
The MultiLogPRO’s internal memory stores experiment
notes and instructions for carrying out the experiment, which
can be edited or expanded at any time. These features
enable MultiLogPRO to function independently from a
computer - a perfect solution for when there is a shortage of
computers in the laboratory.
MultiLogPRO can record data from up to 8 sensors simultaneously; it is capable of
recording at rates of up to 21,000 samples per second, and of collecting up to
100,000 samples in its internal memory.
MultiLogPRO is very easy to use because all its functions are broken down into 8
icon menus, and its four buttons can browse every menu and execute any of the
commands. In addition, when a sensor is plugged in, the MultiLogPRO automatically
recognizes the type of sensor, and will record the data with the appropriate units.
A rechargeable battery powers the data logger, which shuts off automatically after 15
minutes have passed since the time of the last data recording, since the time the last
button was pressed, or since the time the last communication with the PC.
MultiLogPRO includes a built-in, easy to use, accurate Timer module that enables
the measuring of several types of timing events.
Together with the TI–83 Plus calculator, MultiLogPRO becomes a complete portable,
handheld data collection and analysis system.
The large variety of sensors with which MultiLogPRO is compatible makes the unit a
true digital Lab, which can measure scientific phenomena from the fields of Physics,
Chemistry, Biology and the environmental sciences.

Figure 1: MultiLogPRO external connections
1. Sensor Inputs
Sensor input/output (I/O) sockets are marked on the MultiLogPRO casing as I/O-1,
I/O-2, I/O-3 and I/O-4. These sockets are used to connect the sensors. Normally, all
four sockets can be used simultaneously.
To connect a sensor to the MultiLogPRO use one of the mini-din cables. Plug one
end of the cable into the data logger - arrow facing up, and the other end into the
sensor - arrow facing down.
If you are using one sensor only connect it to input 1. If you are using two sensors
connect them to inputs 1 and 2, and so on.
In order to connect more than 4 sensors at a time, use Fourier splitter cables (Part
Number DT011), which will enable the connection of up to 8 sensors simultaneously.
When a splitter cable is connected, it must be connected to the socket in the correct
numerical order (e.g. for 5 sensors, connect the splitter cable to I/O-1). One of the

two splitter cables is marked with arrows - that is the main input (the lower I/O
number), the second line is marked with the letter S (split) - indicating that it is the
secondary input (the higher I/O number). Connect up to four input splitters to split the
MultiLogPRO’s inputs starting with I/O-4 (the splitters must be connected in order):
•I/O-1 splits into I/O-1 and I/O-8
•I/O-2 splits into I/O-2 and I/O-7
•I/O-3 splits into I/O-3 and I/O-6
•I/O-4 splits into I/O-4 and I/O-5
Note: Before connecting the mini-din cable to the data logger or the sensor
sockets, make sure that the mini-din plug is correctly positioned in front of the
socket. Connecting the cable in an awkward position might cause damage to the
cable pins.
2. Computer USB communication socket
For USB communication between logger and the computer, connect the USB Type B
plug to the MultiLogPRO and the USB Type A plug to the computer.
3. Computer serial communication socket
For Serial communication between logger and computer, connect the 9-pin Type D
cable between this port and one of the computer’s COM ports. At the back of the
computer you will find a 9-pin Type D male socket. If your computer is using this port
for the mouse, look for a 25-pin D shell male socket near the mouse. Use the RS-232
9 to 25-pin adaptor to connect the MultiLogPRO serial cable to the 25-pin port (the
adaptor is included with the MultiLogPRO).

4. External DC power supply socket
Plug in an AC/DC 9-12V adaptor whenever you want to save battery power, or to
charge the battery when necessary. Connecting external power to the MultiLogPRO
automatically charges the internal battery. The adaptor should meet the required
specifications (see section 0).
Battery
MultiLogPRO is equipped with a 7.2V NiCad rechargeable battery. Before you first
start working with MultiLogPRO, charge the unit for 10 to 12 hours while it is turned
off. Battery life is approximately 24 hours between charges.
If the data logger’s main battery runs out, the internal 3V Lithium battery backs up
the memory, so no data will be lost.
Note: Before storing the data logger make sure you have unplugged all the sensors
and pressed the OFF key.
AC/DC Adaptor
Output: Capacitor filtered 9 to 12 VDC, 400 mA
Female plug, center Negative
Automatic Shut-off
MultiLogPRO shuts off automatically after 15 minutes have passed since the time of
the last data recording, the time the last button was pressed, or the time the last
communication was made with the computer.
Standalone Operation
One way to program the MultiLogPRO is to use its keypad and screen (the other way
is to use the MultiLab software - see Error! Reference source not found.). The
keypad allows us to set all the parameters for data collection, while the LCD screen
displays the setting values.

Input Modes
MultiLogPRO has two Input Modes. The default mode is Auto ID and the
MultiLogPRO is in this mode when turned on for the first time. When using more than
4 sensors, when using third-party sensors, or if you’ve defined your own sensor,
switch to the 8 inputs mode. Select the system configuration menu in the MAIN
MENU and choose the mode you want (see page 21).
MultiLogPRO saves the current mode selection and will open in that mode the next
time you turn it on.
Auto ID
Automatic sensor identification –just plug in the sensors and the MultiLogPRO
prepares itself to collect data from these sensors.
While in this mode you can work with up to 4 sensors simultaneously.
8 Inputs
This mode enables data logging from up to 8 sensors simultaneously. Connect up to
four input splitters (DT011) to multiply the MultiLogPRO’s inputs starting with I/O-4
(the splitters must be connected in order):
•I/O-1 splits into I/O-1 and I/O-8
•I/O-2 splits into I/O-2 and I/O-7
•I/O-3 splits into I/O-3 and I/O-6
•I/O-4 splits into I/O-4 and I/O-5
In the splitter cable, one of the two wires is marked with arrows - that is the main
input (the lower I/O number). The second wire is marked with the letter S (split) -
indicating that it is the secondary input (the higher I/O number).
To learn how to switch to 8 inputs mode please refer to section 0 on page 21.
In this mode there is no automatic sensor identification. Select the sensors manually
either from the MultiLogPRO setup menu (see section 0 on page 15) or using the
MultiLab software (see section Error! Reference source not found. Error!
Bookmark not defined.).
Use this mode if you want to work with more than 4 sensors or if you are using third-
party sensors.

Before you first use MultiLogPRO, charge the unit for 10 to 12 hours while it is turned
off.
Turn on MultiLogPRO
Press the on button . You will see the initialization screen. MultiLogPRO
performs a brief self-check and displays its status including battery level. At this point
you can load the last setup you used (see page 20). If you need a new setup wait
until you see the Main Menu screen:

Measuring Timing Events
MultiLogPRO incorporates an accurate Timer module with resolution of 0.1ms. The
timer can measure several types of events triggered by Fourier Systems' photogates:
Time and speed with one photogate
Time and speed between two gates
Time, speed and acceleration between two gates
Stopwatch
To learn more about the different measurement types see page Error! Bookmark
not defined. and page Error! Bookmark not defined..
While in Timer mode MultiLogPRO does not store data. To save timing data in the
computer operate the Timer module via MultiLab.
To learn how to use the timer with MultiLab software please see section 4.9.
To use the photogates together with other sensors operate MultiLogPRO as a data
logger and then analyze the photogate data with the aid of MultiLab's Timing Wizard
(see page Error! Bookmark not defined.).
