Sensor lead resistance: max. 30Ω per lead with three wire circuit
Measuring current: approx. 250µA
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.
