9. SOFTWARE INSTALLATION
9.1 DESCRIPTION OF INSTALLATION CD AND ITS RUNNING
The attached CD contains all the necessary software for the use of Multi-Diag Scope system including the
accompanying files such as user’s manuals, prospectuses.
Insert the CD in your CD-ROM drive. If the CD does not run automatically, run the MultiScopeInstall program
which you will find on the CD.
9.2 INSTALLATION OF MULTI-DIAG SCOPE PROGRAM
If you install the program on the computer with Windows 2000/XP/Vista/7/8.1/10 operation system, log in
as a system administrator.
The installation is intuitive, guided by an installation wizard displayed on the PC screen.
The installation may take several seconds. Click on “Finish” to complete the installation.
The pre-installation of drivers for the RS232-USB converter starts after its completion (see Chap. I - 10.2.1)
Note:
The default language of the Wizard is English but it can correspond to your language version of Windows
9.3 PROGRAM CONFIGURATION

9.4 PROGRAM AUTO UPDATE
When the program is started up and the initialization window is displayed (see Fig. 25), the system automatically
verifies which program versions are in the computer and in the Multi-Diag Scope and Motortester modules.
If there is a newer version in the computer (after the UpDate installation from the CD), the internal software (the
so-called firmware) will be overwritten either directly in Multi-Diag Scope or in the Motortester module. The
indications are described in the following chapters Chap. I - 9.4.1 and Chap. I - 9.4.2. When the overwriting is
finished, the Multi-Diag Scope program is automatically started up.
Note:
The overwriting takes a few tens of seconds or some minutes.
In the case of problems with overwriting (the so-called „”stalling“), we recommend switching off the
power supply. After the reconnection and the program start-up everything will be reinitialized.
In the case of computer “freezing“ we recommend restarting the computer.
9.4.1 AUTO UPDATE INDICATION ON THE SCREEN
When the auto update is in progress in Multi-Diag Scope or in the Motortester module, this state is indicated
on the screen with the “Loading firmware“ flashing message - see the cursor in Fig. 12.
9.4.2 AUTO UPDATE INDICATION ON MULTI-DIAG SCOPE
When the auto update is in progress in Multi-Diag Scope or in the Motortester module, this state is indicated
with a flashing LED indicator on Multi-Diag Scope (see the cursor in Fig. 13).
Quick flashing = overwriting in the Motortester module
Slow flashing = overwriting in Multi-Diag Scope
Fig. 12 –Initializing window with the message that firmware is
being updated in Multi-Diag Scope or in Motortester module

10.2 INSTALLATION OF THE USB-RS 232 CONVERTER
The USB-RS 232 converter (see Fig. 15) ensures communication between the Multi-Diag Scope and a PC (or
Laptop)
Fig. 15 –RS232-USB converter
10.2.1 INSTALLATION OF DRIVERS FOR THE USB-RS 232 CONVERTER
P After you have clicked on the “Finish” button to complete the Multi-Diag Scope installation, it is also necessary
to pre-install the drivers for the RS232-USB converters.
After the start of the installation wizard (see Fig. 16) , as the first step, the search for older (invalid) drivers takes
place (see Fig. 17).
The following series of figures was taken from the installation wizard for the Windows XP operating system. The
wizard for Windows Vista is similar but with a different picture:
Fig. 16 –Start of the pre-installation of RS 232-USB converter
drivers
Fig. 17 –Search for older (invalid) drivers
a) If old drivers are detected, the information about their presence will be displayed (see Fig. 18)
together with a suggestion for their removal. It is recommended that you remove the old drivers.

Fig. 18 –The result of a search for old drivers –it is recommended to
uninstall them (Ano/Yes)
Fig. 19 –A warning of the Windows XP operating system is displayed
(for further details see the Note below)
The actual driver pre-installation ensues which will be later used for the detection of new hardware after the
connection of the RS232-USB converter to the USB port. This process ensures that the installation CD will not be
necessary again.
Warning:
If the old drivers are not removed, the new drivers will not be installed and the correct operation of the RS232-
USB converters cannot be guaranteed.
Note to Fig. 19:
A warning of the OS Windows XP informs that the installed driver was not certified by Microsoft. This notification
can be displayed in the process of installation several times and it is possible to ignore it without any concerns!
When the installation of the new drivers is completed, a notification is displayed informing about the need for
restarting the system (see Fig. 21). It is recommended to perform this restart.
b) If up-to-date drivers are detected, the information about their presence will be displayed (see Fig.
21) and the Multi-Diag Scope installation will be complete.
Fig. 20 –The result of a search for old drivers (in this case the
drivers are up-to-date)
Fig. 21 –A system requirement for restarting the system –it is
recommended to perform the restart (Ano/Yes)
10.2.2 ADAPTER USB-RS 232 FINAL INSTALLATION
1. Initiation of the converter installation is conditioned by previous successful Multi-Diag Scope
installation.
2. Connect the converter to the PC (insert it into an arbitrary free USB connector)
3. The device has been detected, see Fig. 14.
4. The hardware installation is straightforward and is guided by the installation wizard on the PC screen.

14. CONTROL OF INDIVIDUAL FUNCTIONS AND SETTING OF OSCILLOSCOPE PARAMETERS
In all its functional modes, Multi-Diag Scope is controlled by means of the mouse cursor and mouse left-button.
In the case of the touch screen it is controlled with the “control pencil” by touching the respective symbol or by it’s
moving on the screen. Hereinafter only the control by means of the mouse is mentioned, however in the case of
the touch screen the mouse is replaced with the “control pencil” and therefore by mentioning the mouse we imply
the “control pencil”.
14.1 CONDITIONS FOR MAXIMIZING THE OSCILLOSCOPE WINDOW + RECOMMENDATION
After the program is started (see Chap. I - 12) the maximized application window (full-screen) is displayed in point
0.0 (top left corner) but only under certain conditions.
The ratio of the sides is determined by the width to height ratio. If the ratio falls within the interval of 0.69 to 0.81,
the application fills the entire screen in the ratio of 4:3. In other cases (outside the interval of 0.69 to 0.81) the 4:3
ratio is forced based on the height or width.
A typical wide-screen ratio is 16:9 (or the width of 16 to the height of 9).

Chap. I - Multi-Diag Scope Basic User’s Manual
Scope_manual_en-v110.docx —14 —
Examples of the oscilloscope's display modes according to the monitor resolution:
800x600........... ratio = 0.75 .........(4:3)............see Fig. 30 –
1024x768......... ratio = 0.75 .........(4:3)............see Fig. 30 –
1280x1024....... ratio = 0.8 ...........(4:3)............see Fig. 30 –
1680x1050....... ratio = 0.625 .......(16:9)..........see Fig. 31 –(monitor will have a stripe on the right
hand side)

Recommendation:
To use maximum possible space for displaying the
oscilloscope, it is recommended to hide the main panel.

14.2 OSCILLOSCOPE
14.2.1 BASIC SCREEN
Notice:
The following set of figures describes the independent oscilloscope. The figures were mostly taken
from the Multi-Diag Scope 1.00 version, eventually from 4.0, 5.1, 6.1, 7.3 or 10.1 versions. However
the description is identical for all versions.
For your better orientation, every figure is accompanied with a note in brackets indicating the version
of the given figure. If there is no note, the figure is from the current version.
The description of the oscilloscope connected with a motortester is presented in a separate chapter
about the motortester (Chap. II - Multi-Diag Motortester).
