Minimum distance between ASP and AEP = 20 % of the measuring range�
In the set measuring range the output signal is between 4 and 20 mA�
For an output signal > 20 mA the volumetric flow quantity is above the final value
of the measuring range�
4.5 Customer-specific calibration (CGA)
The customer-specific calibration allows changing the gradient of the curve of
measured values (→ 10.4.5). It influences the display and the outputs.

A = operating value for display and
output signals
Q = flow
MEW = final value of the measuring range
V0 = curve of measured values with
factory setting
V1, V2 = curve of measured values after
calibration
The change in the gradient is indicated in per cent� Factory setting = 100 %� After
a change the calibration can be reset to factory setting (→ 10.5.3).
