UP Interface thickness (= thickness of upper medium)
On the local display, the measured interface thickness is indicated together with the
manual interface thickness. By comparing these two values the device can
automatically adjust the dielectric constant of the upper medium.
Measured thickness upper layer
Navigation  Setup → Advanced setup → Interface → Measured thickness upper layer
Description Displays the measured interface thickness. (Thickness UP of the upper medium).
DC value 
Navigation  Setup → Advanced setup → Interface → DC value
Description Displays relatvie dielectric constant ε
r
of the upper medium (DC
1
) before correction.
Calculated DC value
Navigation  Setup → Advanced setup → Interface → Calculated DC value
Description Displays calculated (i.e. corrected) relative dielectric constant ε
r
(DC1) of the upper
medium.
