Sensor lead resistance: max. 30 Ω per lead with three wire circuit
Measuring current: approx. 250 µA
Lead compensation: Not required for three wire circuit. For a 2-wire
circuit, the lead resistance can be compensated by correcting the
actual value.

The accuracy values refer to the maximum measuring range.
Small measuring ranges lead to reduced linearisation accuracy.
