Probe Connection
The magnetic measuring probe is plugged into the probe port (DIN Mini-DIN-
socket) on the top of the device.
Note
Only use measuring probes which are approved by the manufacturer
to operate with this device.
Note
The probe plugs must not be connected to the electric potential, the
protective conductor or the plug shell. If you measure near current
conducting parts, make sure that there is sufficient distance and a suf-
ficiently good insulation.

USB Interface
The transmission of the measuring values and the entire gaussmeter control
are possible via the installed standard USB interface.
The interface is specified according to the USB (Universal Serial Bus) 2.0.
The interface is not insulated. Please note that the shielding of the measur-
ing probes (e.g. the metallic handle) might be connected to the protective
conductor of your personal computer via this USB interface.
The device supports two USB device classes. On the one hand the HID
class. In this mode the data can be entered directly into any program. The
gaussmeter acts similar to the keyboard of a personal computer.
On the other hand, the device can be operated in the USB device class
CDC and thereby emulates a virtual serial interface on the personal com-
puter or another processor. In contrast to the HID mode, the installation of
a driver on the processor becomes necessary here.
Via the virtual serial interface all functions and parameters of the device
can be set using the SCPI command, and the measuring values can be
read out automatically.
