Chap. I - Multi-Diag Scope Basic User’s Manual INTRODUCTION The Multi-Diag Scope measuring system is designed for the diagnostics and repairs of motor vehicles. It enables to measure and follow the courses of electrical voltage signals or of signals (e.g. current, pressure, ...) which can be conversed in the voltage signal by appropriate sensors.

SOFTWARE INSTALLATION 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.
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 “Loading firmware“ flashing message - see the cursor in Fig. 12.
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.
(Ano/Yes) 10.2.2 ADAPTER USB-RS 232 FINAL INSTALLATION Initiation of the converter installation is conditioned by previous successful Multi-Diag Scope installation. Connect the converter to the PC (insert it into an arbitrary free USB connector) The device has been detected, see Fig. 14.
PROGRAM MULTI-DIAG SCOPE START UP To start the program up, click on the Multi-Diag Scope icon on the monitor desktop (see Fig. 24), or on the Multi- Diag Scope option from the „Start\Programs Multi-Diag “ program group (see Fig. 23).
