2.2.5 Polarity Setting Mode (Unipolar/Bipolar)
As the 6146/6156 produces bipolar output power, the source value can be changed from positive polarity
to negative polarity continuously through key operations.
However, such continuous variation can be prohibited by changing the polarity setting mode to unipolar.
This can prevent the load from being damaged by unexpected polarity switching. This mode offers the
same operability as that of the former model 6144 that produces unipolar output power.
