401 flow sensor shows following result:
1% af qp: +1.1%
10% af qp: +0.3%
100% af qp: -0.1%
To adjust the deviation following corrections must be typed in:
1% af qp: -1.1%
10% af qp: -0.3%
100% af qp: +0.1%
Adjustments larger than +/-5% should not be carried out, as this might be caused by a faulty flow sensor.
