1.4 Technical data
1.4.1 Evaluation unit F 5673
(not the measuring range)
The temperature (TT) at the measuring point is measured via a sensor inte-
grated in the humidity sensor or entered by hand. The pressure (SP) is
measured via a 4...20 mA signal from an external pressure transmitter or
entered by hand. CO
2
-content (0...100%) is measured via a 4...20 mA-
signal or entered by hand.
Max. 3 measurements / minute per channel
