+Description:
+ For differential channels, this an offset that is applied
+ equally to both inputs. As the reading is of the difference
+ between the two inputs, this should not be applied to the _raw
+ reading by userspace (unlike _offset) and unlike calibbias
+ it does not affect the differential value measured because
+ the effect of _zeropoint cancels out across the two inputs
+ that make up the differential pair. It's purpose is to bring
+ the individual signals, before the differential is measured,
+ within the measurement range of the device. The naming is
+ chosen because if the separate inputs that make the
+ differential pair are drawn on a graph in their
+ _raw units, this is the value that the zero point on the
+ measurement axis represents. It is expressed with the
+ same scaling as _raw.
