The flow rings are inserted face-up so that the cable
passes through the recess in the C-ring.
The measuring fan and the rings are labeled with the
device number CE XXXX. The calibration of the rings is
only valid together with the corresponding fan.
On delivery, the fan cap is in the accessory bag.
