NOTE!
The technical data resulting from the various modes are
specified in
“3. Technical Data” on page 9.
0
Transmit signal The transmit signal of the sensor can be switched off. This allows the
sensor to be deactivated when not in use and, if necessary, interference
can be avoided.
On
Transmit signal is on.
Off
Transmit signal is off. No measurements are taken. The switching behav-
ior is identical to when no signal is received in reflective operation or as
a through-beam sensor.
On
Sonic cone
This setting can be used to adjust the shape and range of the sonic
cone. The diagrams for the individual sonic cones on standardized ob-
jects can be found in
“3.4 Sonic Cone Diagrams” on page 12.
Narrow
cones can be used to block out constant disturbances in the measuring
section (e.g. tank walls).

The measured distance can be read out in millimeters or inches.
Millimeter
Read-out of distance values in mm for internal temperature compensa-
tion or external temperature compensation via the parameters
Inch
Read-out of distance values in 1/10 inch for internal temperature com-
pensation or external temperature compensation via the parameters
Millimeter (with external temperature)
Output of distance values in mm and input of external temperature via
Process Data Out
Inches (with external temperature)
