Maintenance

If the instrument is used correctly, no maintenance is required in
normal operation.
9.2

Diagnosis memory

The instrument has several memories available for diagnostic pur-
poses. The data remain there even in case of voltage interruption.
Up to 100,000 measured values can be stored in the sensor in a ring
memory. Each entry contains date/time as well as the respective
measured value. Storable values are for example:
•
Distance
•
Filling height
•
Percentage value
•
Lin. percent
•
Scaled
•
Current value
•
Meas. certainty
•
Electronics temperature
When the instrument is shipped, the measured value memory is
active and stores distance, measurement certainty and electronics
temperature every 3 minutes.
In "Extended adjustment" you can select the respective measured
values.
The requested values and recording conditions are set via a PC with
PACTware/DTM or the control system with EDD. Data are thus read
out and also reset.
Up to 500 events are automatically stored with a time stamp in the
sensor (non-deletable). Each entry contains date/time, event type,
event description and value. Event types are for example:
•
•
•
Status messages (according to NE 107)
•
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
