Safety
!
The “MEphisto Scope 1” has a maximum input voltage of ±10 VDC.
Measuring higher voltages than this directly may damage the instrument and invalidate the warranty. The instrument is not galvanically
isolated - i.e. the ground of the internal circuitry connects directly to the
ground of the host pc via the USB supply. To measure high voltages such as mains
supplies use a high voltage differential probe for your personal safety and to prevent
damage to the instrument. Please follow the appropriate standards, installation
instructions and national safty standards. Meilhaus Electronic GmbH assumes no
responsibility for damage in case of faulty installation, operation or handling.

“MEphisto Scope 1” - Features
“MEphisto Scope 1” combines the functionality of an oscilloscope, a digital volt
meter (DVM), as well as 24 discrete digital I/Os in a single compact device. The
module is powered from the PC via the USB interface; no external power supply is
necessary.
Both analog inputs have BNC connectors for standard oscilloscope probes. Each
channel has it’s individual 16 Bit A/D converter which gives you simultaneous
sampling rates of 1 MS/s on both channels. The input range is ±10 V. Multiple
trigger options can be selected to start an analog acquisition. The 24 discrete
digital I/O channels (TTL) can be congured as input or output individually.
The “MEphistoLab” software which is included with the device, is a virtual
instrument panel, that gives you easy and quick access to all functions of the device
under Windows 98SE, Me, 2000 and XP. The software requires the installation of
the Agilent VEE runtime software version 7.0 (included on CD-ROM).

Getting Started
1. Connect the “MEphisto Scope 1” to a USB port of your PC using the USB cable
included with the device. ⇒ The hardware wizard will automatically detect the
new USB device and will display the message “New hardware found”. The following description is to be orientated towards Windows XP but is also valid for
2. Insert the installation CD-ROM included with the package into the CD drive of
older Windows versions in an analog way. However the dialogs may differ slightly
depending on your Windows version.
your computer.
3. In the hardware wizard select the option “Search for a suitable driver for my
device (recommended)” and click “Next”. If Windows displays a message, telling
you the driver is not Microsoft certied, just skip this window.
⇒ The system driver will be installed and the entry “MEphisto Scope 1” will be
added in the device manager under the device class “Meilhaus DAQ Boards”.
4. End the installation of the system driver by „Finish“ and continue with the installation of the “MEphistoLab” software as follows:
5. With the CD still inserted in your drive, navigate to the directory [CD drive]:
\software\MEphistoLab\disk1 and start the installation of the “MEphistoLab”
software by double-clicking the le “setup.exe”.
! Please read the dialogs of the installation program carefully. If required, the
Agilent VEE runtime software will be installed automatically.
⇒ After the installation has nished you will nd the “MEphistoLab” software in
your Windows “Start” menu under “Programs - Meilhaus MEphistoLab”.
