MEW = value of measuring range
The output signal is between 4 and 20 mA in the set measuring range.
It is also indicated:
Flow above the measuring range: output signal > 20 mA.
Customer-specific calibration
(CGA)
This calibration changes the
slope of the curve of measured
values. It influences the display
and the analog output.
Calibration is only possible for
values > 25% of the final value
of the measuring range.
It can be reset (→ menu item
CAr).
