Output current
Navigation  Setup → Advanced setup → Curr.output → Output curr.
Description Shows the actual calculated value of the output current.
User interface 3.59 to 22.5 mA
Damping output 
Navigation  Setup → Advanced setup → Curr.output → Damping out.
Description Define time constant τ for the damping of the output current.
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 there is no damping.
User entry 0.0 to 300 s
Turn down 
Navigation  Setup → Advanced setup → Curr.output → Turn down
Description Using the turn down functionality it is possible to map a section of the measuring range to
the total range of the output current (4-20mA).
The section is defined by the '4 mA value' and '20 mA value' parameters.
Without the turn down, the complete measuring range (0 to 100%) is mapped to the
current output (4 to 20mA).
