modes via the serial interface using the Monitor BUF (310) service appli-
cation included in the UBViewer ModBus program. The installation file
can be downloaded from the delivery set.
The UBViewer ModBus program works under Windows XP operating
systems (Vista, Windows 7, Windows 8, Windows 10). For the installation
of the program on the PC, open the installation file and follow the instruc-
tions appearing on the monitor.

computer serial port (via RS-232/RS-485 signal adapter) or the computer
USB port (via USB-RS-232/RS-485 signal adapter).
Set the flow meter to SERVICE mode by setting a jumper on the cor-
responding contact pair. Start the "UBViewerProjects" file on the com-
puter from the folder where it was loaded during installation. The UB-
Viewer ModBus menu bar appears on the monitor. Open the "AFLOWT
BUF M (310).vpr" file, and the
