Error messages (according to NE 107)
The data are read out via a PC with PACTware/DTM or the control
system with EDD.
The echo curves are stored with date and time and the corresponding
echo data. The memory is divided into two sections:
Echo curve of the setup: This is used as reference echo curve for
the measurement conditions during setup. Changes in the measure-
ment conditions during operation or buildup on the sensor can thus
be recognized. The echo curve of the setup is stored via:
•
PC with PACTware/DTM
•
Control system with EDD
•
Display and adjustment module
Further echo curves: Up to 10 echo curves can be stored in a ring
buffer in this memory section. Further echo curves are stored via:
•
PC with PACTware/DTM
•
Control system with EDD
•
Display and adjustment module
