The following accuracy is specified for one single channel (channel 1 or channel 2). If
dual channels are used at the same time, additional % of accuracy should be added to
the listed accuracy. Please refer to the supplemental dual channels specification. The
following accuracy is also specified for the ZEROED (relative) value. The accuracy is
given as ±% of reading± number of least significant digits.
