Process Variable Offset
The Process variable offset is used to modify the measured process variable value. Use this
parameter to compensate for errors in the displayed process variable. Positive values are
added to the process variable reading, negative values are subtracted.
Caution: This
parameter is in effect, a calibration adjustment; it must be used with care. Injudicious use
could lead to the displayed value bearing no meaningful relationship to the actual process
variable. There is no front panel indication of when this parameter is in use.
Settings = ±input span
Default Value = Off.
Also refer to: Input Span and Process Variable.
Profile Control Menu
If the Profiler option is fitted, the menu is available from the Main Menu. It allows the user to
choose the profile to run, and then control that profile (run, hold, abort, skip to next segment
etc.).
Refer to the Profiler Control Menu information in the Configuration & Use section.
Also refer to: Main Menu, Profile Setup Menu, Profiler and Profiler Mode.
Profile Events
Events are outputs that can be made active during a profile segment, or segments. There are
5 possible events, each of which can be defined to be active or inactive for the duration of
each segment, from the Profile Setup Menu. For end segments, events selected to be active
stay on until the unit exits from profiler mode or a new profile runs. It is possible to link event
outputs to certain alarm outputs in a logical AND situation.
