  • Page 34 ZOK-E/-Z 10.3.4 Signal Input / Filter In case of discontinuous input signals, the integrated filter function can filter the display of flow rates, the analogue output and the switching outputs (only options E3/Z3). Despite filtering effect, the reaction time to rapid changes in the flow rate can be kept low by appropriate choice of filter parameters.

  • Page 41 ZOK-E/-Z 10.7.3 Switching Output / Output 1+2 / Output type Parameter "Output" defines the function of the transistor output. NPN, PNP or PP (Push-pull) output types are available. The push-pull type combines NPN and PNP and is therefore the best choice for most wiring. All outputs are equipped with short circuit and overload protection.

As a standard, this value is always set at the last value of measuring range. However, this can be defined at any point in the measuring range (however always greater than measuring range starting value).
