Lower range limit parameterizable from X1n ... X1n + 0.8
(X2n – X1n) and range span parameterizeable from 0.2
(X2n – X1n) ... (X2n – X1n).
Deadband 0.25 % of range span
Setting time 2 s
Attenuation of the meas. value with low-pass filter of 1st order;
Time constant 0 ... 60 s per measuring channel, can be parame-
terized.
Root-extraction function can be parameterized with DC current
and DC voltage measuring ranges.
