15.5.9 Enabling the cut-off function of the mass flow rate
If the absolute (and possibly damped, see chapter 15.5.2) measured mass flow rate is less than the cut-off
value plus an hysteresis value, the mass flow rate value is set to 0:
• the display then shows a mass flow rate = 0.
• the outputs and the totalizers react as if the actual mass flow rate were equal to 0.
