Example: dSt for window function
1 Volumetric flow quantity Q reaches 0.5% of VMR → dSt starts, output becomes active.
2 dSt elapsed, Q reached good range → output remains active.
3 Q above SP (leaves good range) → output is reset.
4 Q again below SP → output becomes active again.
5 Q below rP (leaves good range) → output is reset again.
6 Q reaches again 0.5 % of VMR → dSt starts, output becomes active.
7 dSt elapsed, Q has not reached good range → output is reset.
8 Q reaches good range → output becomes active.
4.8 Customer-specific calibration (CGA)
This calibration changes the slope of the curve of measured values� It influences
the display and the outputs�

The change in the increase is indicated in percent� 100% corresponds to the fac-
tory calibration. It can be reset(→ 9.5.5).
