Normally the Measurement Mode does not need to be changed. The
transmitter is pre-configured according to the specified model:

Interface Immersed Probe is used for applications where the probe is fully
immersed in liquid. In this mode the transmitter ignores the upper product
level. See Section 6: Interface measurements with fully immersed probes for
more information.
NOTE!
Only use Interface Immersed Probe for applications where interface is
measured for a fully immersed probe.
Enter the angle between the probe and the vertical line. The default value is
equal to zero. Do not change this value if the transmitter is mounted with the
probe along the vertical line (which is normally the case).
For interface measurements the Maximum Upper Product Thickness
parameter may be used in special cases when the dielectric constant of the
upper product is relatively high. By setting this parameter you can avoid that
interface measurements are getting out of range.
The default Damping value is 10. Normally this value does not need to be
changed. The Damping parameter determines how quickly the transmitter
responds to level changes and how robust the measurement signal is against
noise. See "High Level Rates" on page 6-7 for more information.
Choose which variables to be displayed and the desired language to be used.
The display toggles between the selected variables every two seconds.
