5. INSTALLING THE MEASUREMENT pROGRAM
Before you connect the DSO to a computer, install the measurement program.
Switch on the computer and start the operating system.
Insert the enclosed software CD into the CD drive and close it. The automatic start mode will automatically
start the installation of the measurement program.
If this does not happen automatically, start the program "setup.exe" by double-clicking on the drive holding
the CD-ROM in the Explorer of your operating system. The software installation will start.
Please follow the on-screen instructions.
In the start menu's program manager, a new folder called "DSO-XXXX" is created.
Leave the CD in the drive, for device installation.
6. CONNECTION AND INSTALLATION OF THE DSO
Plug the round DC plug of the mains adapter into the power supply jack (12) on the back of the DSO and
connect the mains adapter to a mains socket. The status LEDs (6) will light up.
Connect the provided USB connection cable with a free USB port at your computer and then with the USB
connection (11) at the DSO.
The operating system recognises the new hardware and starts the "Hardware Wizard".
Follow the on the screen instructions.
Choose the installation option "Install software automatically (recommended)" and press "Continue".
The system searches for the compatible driver. Follow the instructions on screen until, you are asked to
restart the operating system. Restart the computer, to update the new installation.
7. STARTING THE MEASUREMENT pROGRAM
Start the computer and connect the USB connector from the computer to the DSO, before starting the
program. Open the start menu, or the "DSO-XXXX" program on the desktop screen, by double-clicking on
the icon.
The measurement program's start screen appears and initialises the DSO. Select your model, if necessary.
The DSO is ready for use.
Connect the test probe for the measurement input at the input for CH1 to CH4 (2 - 5). The generator output
occurs at the BNC output "OUTPUT" (8).
A ll parameters for the DSO are set automatically using the program key "AUTO" (Autoset), so
that the optimum signal display appears on the screen.
8. CLEANING
Always observe the following safety instructions before cleaning the device:
L ive components may be exposed if the covers are opened or parts are removed, unless
this can be done without tools.
p rior to cleaning or repairing of the device, all cables have to be detached and the device
has to be turned off.
Do not use any scouring cleansers, petrol, alcohol or the like to clean the product. These might attack the
surface of the device. Furthermore, the fumes are hazardous to your health and are explosive. Moreover,
you should not use sharp-edged tools, screwdrivers or metal brushes or similar implements for cleaning.
For cleaning the device or the display and the measuring cables, use a clean, slightly damp, fuzz-free,
antistatic cloth.
I f you have technical questions concerning the use of the device, feel free to contact our
technical support.
9. DISpOSAL
Electronic products are raw material and do not belong in the household waste. When the de-
vice has reached the end of its service life, please dispose of it, according to the current statu-
tory requirements, at your local collection site. Disposal in the household waste is prohibited.
