4.7 Setting of the standard conditions of the volume flow
The unit is adjusted to a standard volume flow to DIN ISO 2533, i�e� volume flow
at 1013 hPa, 15 °C and 0 % relative air humidity�
The unit can be set to different standard conditions:
• Via the menu item [rEF�P] the standard pressure is set, which serves as a refer-
enceforthemeasuredanddisplayvaluesforvolumetricflow(→9.5.5).
• Via the menu item [rEF�T] the standard temperature is set, which serves as a
referenceforthemeasuredanddisplayvaluesforvolumetricflow(→9.5.6).
4.8 Low flow cut-off (LFC)
Withthisfunctionsmallvolumetricflowquantitiescanbesuppressed(→9.5.7).
Flows below the LFC value have no effect on the display and output signals�
Example: For LFC = 0�5 volumetric flow quantities below 0�5 Nm³/h are sup-
pressed�
