Fixed current 
Navigation  Setup → Advanced setup → Curr.output 1 to 2 → Fixed current
Prerequisite Current span (→  151) = Fixed current
Description Define constant value of the current.
User entry 4 to 22.5 mA
Factory setting 4 mA
Damping output 
Navigation  Setup → Advanced setup → Curr.output 1 to 2 → Damping out.
Description Define time constant τ for the damping of the output current.
User entry 0.0 to 999.9 s
Factory setting 0.0 s
Additional information Fluctuations of the measured value affect the output current with an exponential delay,
the time constant τ of which is defined in this parameter. With a small time constant the
output reacts immediately to changes of the measrued value. With a big time constant the
reaction of the output is more delayed. For τ = 0 (factory setting) there is no damping.
Failure mode 
Navigation  Setup → Advanced setup → Curr.output 1 to 2 → Failure mode
Prerequisite Current span (→  151) ≠ Fixed current
Description Select behavior of the output current in case of an error.
