First enter the desired current output configuration into the following blank table with a
pencil. Calculate the resulting signal distance per mA to observe the necessary minimum
slope. Then enter the values in the device.

The characteristic can have a
positive or negative slope for
the measured value output.
In the case of actuating
variable output (O2 = Contr),
an increasing current
corresponds to an increasing
actuating variable.
