SWR Envea M-Sens 2 Operating Instructions Manual page 14

Analog output is modified in menu 5 and can be adjusted to user requirements here
(e. g. 0... 20 mA).
The calibration of the starting value takes place in menu items 5.7 and 5.8.
Standard MIN = 4 mA
The measuring range filter makes it possible to adapt to slower recording
devices or continuous output at the analogue output (power output).
Support points The measurement can be checked for linearity based on varying humidity
values. To improve accuracy, these should be determined respectively.
In case of deviations, the non-linearity can be corrected through a table of
support points. Based on the points that are selected and specified in menus
1.4.2 / 2.4.2 / 3.4.2 / 4.4.2 (a minimum of 2 during first commissioning),
a correction value can now be entered for the actual humidity value.
(This value can be changed later.) A maximum of 5 support points are available.
Saving changes After changes are made, they can be saved using the menu item program
device. The change is carried out once Overwrite calibration is confirmed.
C1-box Is only used when the distance between sensor and analysis unit exceeds 2 m.
MAX = 20 mA
