Correction of the characteristic curve
To correct a custom designed curve branch into menu CUSTOMER TRIM the same way as
when determining the curve.
The inquiry about the CHARACTERISTIC shall be answered by old as the curve filed is large-
ly maintained, with only point 10 being corrected.
All other data (trim points, temperature difference) remain unchanged and are transferred by
pressing M.
The set flow velocity (1.80 m/s) is confirmed at trim point 10 and the automatic calibration as
described under Implementation is started.
The Y value for a flow velocity of 1.80 m/s is shown in the following table.

Another verification of the characteristic curve will show the following test values:
The example shows that after being corrected, trim point 10 is within the required tolerance
of ±5%.
