4 Start-up
• Check that the flowmeter has been correctly installed.
• With separate systems, check before initial start-up that the correct converter (UFC 030 F) is
used with the correct flow sensor (UFS 3000).
• Order No., see instrument nameplates
• Meter size (DN), Function 3.1.5
• Primary constant GK, Function 3.1.6
• Flow direction, Function 3.1.7
• When powered, the signal converter operates in the measuring mode. TEST, NO ERROR and
IDENT NO. _ _ _ _ _ _ _ of the signal converter appear in succession on the display. This is
followed by display of the actual flow rate and/or the internal count on a continuous or alternating
basis (depending on setting, see Function 3.03 Display or Function 1.02 Display).
