The following section displays and describes the parameters which differ
from the description of the “Voltage, current and resistance”.
The parameters apply both to PT100 2-conductor technology
– 30...+ 70 °C and to PT100 2-conductor 200...+ 800 °C. The difference
concerns the accuracy and resolution of he measuring range.
So that the measurement is not corrupted, the return conductor of
a PT100 sensor must be routed separately to the 0 V terminal and
may not be used as a return conductor for other sensors.
