Description Select medium group.
Selection • Others
• Water based (DC >= 4)
Factory setting Others
Additional information This parameter roughly specifies the dielectric constant (DC) of the medium. For a more
detailed definition of the DC use the Medium property parameter.
The Medium group parameter presets the Medium property parameter as follows:
Medium group Medium property
Others Unknown
Water based (DC >= 4) DC 4 ... 7
The Medium property parameter can be changed at a later point of time. However,
when doing so, the Medium group parameter retains its value. Only the Medium
property parameter is relevant for the signal evaluation.
The measuring range may be reduced for small dielectric constants. For details refer
to the Technical Information (TI) of the respective device.
