(Ground)
In order to avoid physical damage and damage to the measuring device and the measuring
objects, you should read the following paragraph carefully and always pay attention to it during
future use. This device may only be used for the intended areas of application.
Warning:
The channels of the oscilloscope are not electrically isolated from one another. Therefore,
the measuring channels should be on a common ground during a measurement. To avoid
short circuits, the earth terminals must not be connected to different, non-isolated DC
levels.
Internal Ground (GND) Wiring Diagram:
Due to the internally connected earth terminals between the BNC socket, USB port and IEC
connector, the mains voltage should not be measured when the oscilloscope is operated
with mains voltage in conjunction with a PC operated with mains voltage. In the event of a
fault, a voltage flashover could occur across the GND of the PC.
