Attribute Semantics
Output Enable
Transducer disabled status overrules the enabled channel processing setup.
Ramp Angle
Ramp angle is held explicitly for information, used to calculate required ramp
differential expansion coefficients for internal processing of Ramp Differential
Expansion. A ‘normal’ probe with a plain target has a ramp angle of 0°. Ramp
angle applies to both probes A and B.
Typical ramps are around 12° (up to 45° on occasion).
Ramp angles can be positive or negative depending on whether a concave/
convex ramp is used
Allowed configuration range: -45…45.
Overall Axial Offset
The channel pair is not currently configured for a differential expansion
application, read attribute requests for attribute 18 returns zero, irrespective of
the actual configured value.

0x4B - x Zero Dual Channel Option to take the current measurement value
and assign to offset attribute (considering the
current setting of this attribute value) such as to
zero the measurement channel.
• To satisfy security requirements, this service
executes if an alarm inhibit is being imposed
via the I/O connection (output) data.
• This code is an instance level service (the
instance that is specified dictates the
particular channel pair
'zeroed').
