Warnings
The “MEphisto Scope” has a
maximum input voltage of ±10 VDC.
Measuring higher voltages than this
directly may damage the instrument and invalidate the warranty.
The “MEphisto Scope” is not electrically iso-
lated, i. e. in „online“ operation the ground of
the device connects directly to the ground of
the PC via the USB cable. If you are using a
standard desktop PC the ground of the de-
vice connects to earth by the power cable
(with protective earth conductor). However,
this reference to earth potential is missing in
case of connection with a laptop or in offl ine
operation.
Therefore a good earthing via the
earth connection at the rear of the housing
and special caution are strictly necessary
for your own safety!
Measuring voltages greater than 42 V, especially mains voltage may only be done by qualifi ed specialists.
Use a high voltage differential probe for this. Note, that there is an electrical connection between the
shield of the BNC connectors and the housing. In „online“ operation it is routed along via the USB cable to the
PC chassis. That is by an accidentially connection e. g. of the live contact of a schuko socket with ground of
your probe, then mains voltage (110 V/230 V) is attached to the housing of the MEphisto Scope.
This means
danger of life!
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.
