Measuring current Pt100 approx. 380 μ A, Pt 500, and Pt1000 approx. 150 μ A; not con-
stant
Lead compensation A lead resistance can be compensated in the software by correcting
the process value.
1 The accuracy values refer to the maximum measuring range. Smaller measuring ranges lead to reduced lineariza-
tion accuracy.
