Sensor head
The sensor head clamps on the conductor being measured, and carries out the
actual current measurement. It is a precision assembly including a molded com-
ponent, a ferrite core, and a Hall effect element. It may be damaged if subjected
to sudden changes in ambient temperature, or mechanical strain or shock, and
therefore great care should be exercised in handling it.

Coarse adjustment trimmer
Use this only when adjustment is not possible within the range of the zero adjust-
ment. Use a nonconductive screwdriver (e.g. ceramic driver) for adjustment.

Probe box
The probe box connects the probe and the oscilloscope via the Rohde
&
Schwarz
probe interface. The Rohde
&
Schwarz probe interface contains a male precision
7
mm (276
mil) BNC connector and six pogo pin connectors. This interface pro-
vides the required supply voltage and is also used to transmit analog signals and
digital data simultaneously. All the analog voltages required by the probe are gen-
erated in the probe box.
The BNC connector is a precision component designed to reach a much higher
frequency limit when connected to an instrument with Rohde
&
Schwarz probe
interface.
Connect the probe only to an instrument with Rohde
&
Schwarz probe interface.
Never connect it to a usual BNC jack, because this can damage the probe inter-
face.
