The CT9000 microprocessor-based
circular recorder offers 1 to 4 trends
with 1 color per channel. The latter
allows future trend addition upgrades
and improves chart annotation of times,
dates, scale values, trend line tags, and
user-configurable real-time actuated
chart messages. This instrument can
accept up to 8 inputs. Some inputs do
not have to be associated with the trend
pens (i.e., display only). Up to 4 process
values can be displayed at one time on
the 40-character vacuum fluorescent
display (2 lines of 20 characters
each). Full English prompts allow easy
configuration. With the recorder’s proven
dotting head print technology, there is
no time difference between trend lines.
This feature, along with the straight
radial time line (compared with the curved
lines on other recorders) allows for
more accurate reading of data. The unit
uses plain paper charts with pre-printed
rings to further enhance readability and
provide better long-term storage.
