Preliminary
eliminates the offsets caused by the SLIC-E/-E2/-P current sensor and the offset caused
by the DC voltage output (Ring offset voltage).
Differential Resistance Calculation:

4.8.2.10 Line Resistance Tip/GND and Ring/GND
The DuSLIC offers the modes of setting either the Tip- or the Ring line to high impedance
or even both by setting the bits HIR and HIT in register BCR1 accordingly. While one of
both lines is set to high impedance, the other line is still active and able to supply a known
voltage. The transversal and/or longitudinal current can be measured and the line
impedance can be calculated.
Because of one line (Tip or Ring) being high impedance, there is only current flowing in
either Tip or Ring line. This causes the calculated current (according
the actual value. Therefore in either HIR or HIT mode the calculated current has to be
multiplied by a factor of 2.
