Configuration for Potentiometer Measuring

Potentiometer measuring is only possible using 3-wire devices.
When a potentiometer is used for measurement, the relative position of the
connected potentiometer is expressed in percent:
x 
100 %
Two settings are available, one for potentiometers with total resistance up to 1.2
kΩ and one for potentiometers up to 5.0 kΩ.
The resolution is 1 digit per 0.0049 %. The increment is determined by the total
resistance RG of the potentiometer. As RG is measured with 16 bit resolution,
using RG = 200 Ω in the measuring range of 5.0 kΩ, the increment is given by
100 %
