The radar sensor as a distance measuring instrument measures the
distance from the sensor to the medium surface. For indication of the
real level, an allocation of the measured distance to the percentage
height must be carried out.

The function " Echo curve memory" makes it possible to save the
echo curve at the time of setup. This is generally recommended, and
it is absolutely necessary if you want to use the Asset Management
functions. If possible, the curve should be saved with a low level in the
vessel.
With the adjustment software PACTware and a PC, a high resolution
echocurvecanbedisplayedandusedtorecognizesignalchanges
during operation. In addition, the echo curve of setup can be dis-
played in the echo curve window and compared with the current echo
curve.
