The medium temperature at which the calibration was made (here: TRIM IS READY!
TEMP = 82 .8 °C) is indicated on the display after the last trim point.
The CUSTOMER TRIM procedure is now completed !
Before quitting the submenu, the calibration data shall be permanently stored by pressing M.
Verification of the solution
In order to verify the curve determined, again set the flow velocity at the various trim points and
compare it to the values indicated by the FC01-Ex during the measuring operation.
Test values are:

The verification of the trim points indicates that trim point 10 is outside the tolerance required.
One of the reasons may be that the flow velocity varied when point 10 was set.
To increase the accuracy at a velocity of 1.80 m/s, that trim point should be redetermined.
