Current range and attenuation of the REC 1
current output in rEC operating mode
(analog output).
Operating notes:
– The setting is carried out in the order:
current range -> attenuation
– Press 1x <ENTER> in between.
The following values can be set:
z Current range:
– 4 to 20 mA, or
– 0 to 20 mA
z "dI" = attenuation dI/dt (in mA/s):
–0.1
–1
–5
–20
Attenuation is the change speed of the
current signal in the case of erratic
changes of the input signal.
