7.2 Parameter adjustment with PACTware
For parameter adjustment of the sensor via a Windows PC, the con-
figuration software PACTware and a suitable instrument driver (DTM)
according to FDT standard are required. The up-to-date PACTware
version as well as all available DTMs are compiled in a DTM Collec-
tion. The DTMs can also be integrated into other frame applications
according to FDT standard.
Note:
To ensure that all instrument functions are supported, you should
always use the latest DTM Collection (from DTM Collection 06/2012).
Furthermore, not all described functions are included in older firm-
ware versions. You can download the latest instrument software from
our homepage. A description of the update procedure is also avail-
able in the Internet.
Further setup steps are described in the operating instructions manu-
al "DTM Collection/PACTware" attached to each DTM Collection and
which can also be downloaded from the Internet. Detailed descrip-
tions are available in the online help of PACTware and the DTMs.
All device DTMs are available as a free-of-charge standard version
and as a full version that must be purchased. In the standard version,
all functions for complete setup are already included. An assistant for
simple project configuration simplifies the adjustment considerably.
Saving/printing the project as well as import/export functions are also
part of the standard version.
In the full version there is also an extended print function for complete
project documentation as well as a save function for measured value
and echo curves. In addition, there is a tank calculation program as
well as a multiviewer for display and analysis of the saved measured
value and echo curves.
The standard version is available as a download under
www.vega.com/downloads and "Software". The full version is avail-
able on CD from the agency serving you.
7.3 Parameter adjustment - Mass flow detection
The parameter adjustment adapts the instrument to the application
conditions.
Note:
During the first setup or after an instrument reset the instrument starts
with an error message (F025 - Invalid linearization table). This is quite
mormal because the sensor doesn't yet have any reference points
for correct operation. Push the button "OK" to acknowledge the error
message.
