9.1 Maintenance

When the device is used correctly, no maintenance is required in
normal operation.

9.2 Measured value and event memory

The instrument has an integrated measured value memory with time
stamp. Up to 100,000 measured values can be saved in the sensor in
a ringing memory. Each entry contains date/time as well as the
respective measured value.
Stored values are for exmaple sensor value, level, current value,
reliability and electronics temperature. The data remain even in case of
voltage interruption.
Via a PC with PACTware/DTM or the control system with EDD, the
requested values and recording conditions are stipulated. Data are
also read our or reset.
The instrument also has an integrated event memory with time stamp.
Up to 500 events are automatically stored in the sensor and are delete
protected. Each entry contains date/time, event time, event description
and value.
Event types are, for example, parameter modifications, status and
error messages as well as switch on and switch off times. The data
remain also in case of voltage interruption.
The data are read out via a PC with PACTware/DTM or the control
system with EDD.
The instrument also has an integrated echo curve memory in which
echo curves can be stored for diagnostic purposes. The echo curves
are stored with date and time as well as the corresponding echo data.
The data remain even in case of voltage interruption. The memory is
divided into two sections:
Echo curve of the setup: here you can store the echo curve as a
reference during setup. This echo curve can be used, for example, to
detect changes of the installation conditions or buildup on the antenna.
Echo curve memory: up to 10 echo curves can be stored in a ring
buffer in this memory section.
The requested values and recording conditions are defined via a PC
with PACTware/DTM or the control system with EDD. Data are also
read out or reset. Depending on the instrument, the echo curve
created during setup can be stored alternatively also via the indicating
and adjustment module.
