7.4.1 Main menu
With the first setup, the instrument offers you a selection of the menu
languages. The selection you are making here can be changed any
time under "

In this menu item, the switching and reset points for hysteresis func-
tion and the lower and upper values for window function are defined
depending on the selected output function.
Hysteresis function
With the hysteresis function (HNO and HNC), the output changes its
state when the measured variable has reached the switching point
(SP). If the measured variable falls below the reset point (RP), the
output returns to its previous state.

If the measured variable moves between switching and reset point,
the state of the output does not change.
