Parameter Description
Lower range Lower process viscosi‐
value viscosity ty value that is mapped
to the lower nominal
range boundary selec‐
ted by Current mode
(8806). Applicable if
Process value (8802) =
21 or 29.
Damping value Time constant of damp‐
ing filter for current out‐
put signal.
Fail-safe behav‐ Current output reaction
ior in case of a fault.
Fail-safe value Output value in case of
a fault and when Fail-
safe behavior (8814) is
configured to 4.
Forced value Forced value when
forcing is active.
Offset adjust‐ Command to trim the
ment lower range value of
the loop current.
Simulate a loop current
of 4.0 mA, measure the
current with an ampere
meter and write the
measured value to this
register.
Gain adjustment Command to trim the
upper range value of
the loop current.
Simulate a loop current
of 20.0 mA, measure
the current with an am‐
pere meter and write
the measured value to
this register.
