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 (→ 9.5.8).
•
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 (→ 9.5.9).
4.9 Low flow cut-off (LFC)
With this function small volumetric flow quantities can be ignored (→ 9.5.5). Flows
below the LFC value have no effect on the display and output signals�
4.10 Customer-specific calibration (CGA)
The customer-specific calibration allows changing the gradient of the curve of
measured values� It influences the display and the outputs�

The change in the gradient is indicated in per cent� Factory setting = 100 %� After
a change the calibration can be reset to factory setting (→ 9.5.7).
5 Installation
The rules and regulations for the installation and operation of compressed
air equipment must be observed�
Installation in pipes:
►
Insert the unit into a G1 process adapter and tighten the nut� Tightening torque
max� 50 Nm� Ensure that the unit is correctly oriented�
5.1 Installation location
