As the reading is of the difference 222 between the two inputs, this should not be applied to the _raw 223 reading by userspace (unlike _offset) and unlike calibbias 224 it does not affect the differential value measured because 225 the effect of _zeropoint cancels out across the two inputs 226 that make up the differential pair. It's purpose is to bring 227 the individual signals, before the differential is measured, 228 within the measurement range of the device. The naming is 229 chosen because if the separate inputs that make the 230 differential pair are drawn on a graph in their 231 _raw units, this is the value that the zero point on the 232 measurement axis represents.
