 Setup → Advanced setup → Current output 1 to 2 → Fixed current
Current span (→  168) = Fixed current
Define constant value of the output current.
4 to 22.5 mA
4 mA
 Setup → Advanced setup → Current output 1 to 2 → Damping output
Reaction time of the output signal on fluctuation in the measured value.
0.0 to 999.9 s
0.0 s
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.
 Setup → Advanced setup → Current output 1 to 2 → Failure mode
Current span (→  168) ≠ Fixed current
Defines which current the output assumes in the case of an error. 'Min.': < 3.6mA 'Max.': >
21.95mA 'Last valid value': Last valid value before occurrence of the error. 'Actual value':
Output current is equal to the measured value; error is ignored. 'Defined value': User
defined value.
