The "DC Output Level" variable is used for assigning a defined offset level to the
analog output signal, e.g. for setting a certain zero offset signal level.
A "DC Output Level" >0 reduces the output range of the measurement
range 0 … 10 V by the selected offset value (F.S.R. - DC output level).
The "DC Output Level" parameter (16-Bit) consists of the high and low byte.
