it must be packaged properly to minimize the risk of damage.
The recommended method of packing is to place the instrument in a container, surrounded on all sides
with at least four inches of shock attenuation material such as styrofoam peanuts.
If the instrument will be subjected to frequent transport then the optional Transport Case shown in
Section 9, Options, might be an economical solution. This wheeled case is very rugged and provides
complete and long term protection against rough handling.

2.3 Warnings and Caution Notices
WARNING: HIGH PRESSURE! High pressure gases are potentially hazardous.
Energy stored in these gases can be released suddenly and with extreme force.
High pressure systems should be assembled and operated only by personnel who
have been trained in proper safety practices.
WARNING: POSSIBLE INJURY! The tubing, valves and other apparatus attached to
the instrument must be adequate for the maximum pressure which will be applied,
otherwise physical injury to the operator or bystanders is possible.
CAUTION: Use the proper pressure medium. Use only clean, dry, noncorrosive
gases. This instrument is not designed for oxygen use.
WARNING: HIGH SOUND LEVELS! Pressures from 1000 psi and up can generate
sound levels above 80 dbA for brief periods when they are exhausted directly to

operator’s responsibility to measure sound levels at whatever point 1 meter from
the equipment that has the highest sound pressure level. At levels above 80 dbA,

calibration parameters on board and have 0.01% IS-50 or optional 0.008% IS-33 uncertainty.
The three transducers, in combination with the internal control valve regulator, provide a dynamic output.
The operator can choose to control pressure either using a single, selected transducer or auto-range
control across all three sensors. The ratio between the highest FS range and the lowest FS range within
the CPC8000 cannot exceed 10:1. The three ranges can be chosen to optimise uncertainty levels across
the full pressure span of the instrument.
In addition to the capacity for three active ranges, a fourth, barometric transducer is available as an
option. With this option installed a CPC8000, with absolute or gauge pressure transducers, can emulate
pressure of the opposite type.
3.1.1 IntelliScale Transducer Choices
The CPC8000 can be supplied with standard 0.01% IS-50 Transducers or optional 0.008% IS-33 trans-
ducers to give a percent of reading uncertainty down to 50% or 33% of full scale respectively. Refer to

3.2.4.2 Screen Navigation
Individual screens are accessed by a series of touches on tabs, buttons or icons, which open screens
within the hierarchy of the instrument. Nomenclature that designated a screen and how to navigate to
it will be given in this manual in the following structure: “Icon name” [Icon Graphic] / [Tab] / [Button
Name].
For example the screen used to set the resolution of the instrument sensor would be designated by
the navigational screen hierarchy, starting from the main screen, as follows: Setup [ ] / [Sensor]
/ [Resolution]. This convention is similar to a computer folder system and will be used to describe a
screen and, inherently, how to navigate to it.
All of the screens are set up into two display areas. The larger area (left 2/3 of the screen) shows live

pressure with absolute pressure instruments, or used for absolute pressure emulation with gauge
pressure instruments.
■ A large 9- inch diagonal color LCD display with glass capacitive touch screen for intuitive operator
interface.
■A very quiet precision pressure regulator with a fast response time.

WARNING! This is class A equipment for emissions and is intended for use in industrial
environments. In other environments, e.g. residential or commercial installations, it can
interfere with other equipment under certain conditions. In such circumstances the operator
is expected to take the appropriate measures.

4.4 Transducer Removal/Replacement
When replacing transducers the order of position MUST be maintained according to
the pressure limit of each transducer; starting with the highest pressure transducer
on the left (Primary Transducer), and the next lower pressure limit transducer next
(Secondary Transducer), and the low ranged transducer at the far right (Tertiary
Transducer). If the system will be operated with less than the full complement of
three pressure modules, any empty slots must begin at the far right where the
Tertiary Transducer is normally located.
The manifold seal is a metal plate used to seal the pneumatic openings on the manifold at
an unused transducer slot. If there is just a single pressure transducer installed then two
manifold seals are installed. All transducer slots must be sealed with either transducers or
seal plates for the instrument to function. Two manifold seal plates are shipped with each
unit for this purpose.
The D-sub connectors for unused slots can remain unplugged. For more information on transducer re-
moval/replacement see Section 10.2.2 in the Maintenance section.
Up to three transducers can be present within the CPC8000. The full scale pressure of the highest
ranged transducer (the Primary transducer) must fall within the range of the installed regulator module
(see Table 4.5, Regulator Module version and range limits). This primary transducer occupies the leftmost

words, the lowest full scale range in the CPC8000 cannot be less than one tenth of the range of the
primary transducer full scale range (see Section 4.6, Transducer Choices).
