Description
Overview
The CPC3000 has a compact-light weight design, a reliable
high speed pressure regulator, gauge / absolute /
bidirectional ranges and an optional barometric reference for
emulation. These qualities make the CPC3000 suitable for a
variety of applications.
Applications
With an Accuracy of 0.025 % FS and a high speed
regulator, the CPC3000 is well suited for use in the
production of
pressure sensors and transmitters or as a working standard
for the control and calibration of all types of pressure gauges.
Functionality
A color touch-screen, combined with user-friendly menus,
guarantees high productivity in a calibration lab or production
facility; all screens can be viewed in several different
languages.
To enter the pressure set point, the operator can choose
between three input modes which can be selected using
the corresponding tab. The input modes are:
1) The numeric key pad menu (shown above) provides a way
Pneumatic High-Speed Pressure Controller Model CPC3000
to enter a specific pressure set point value to be controlled.
2) The step key menu (shown on page 5 section B) provides
defined steps programmed in pressure increments or
percent of full span to move the pressure set point across
the range of the instrument under test. Step key values are
user defined in the setup menu.
3) The jog key menu (shown on page 5 section C) provides a
way for the operator to define small pressure steps up or
down to reach a cardinal point on a dial gauge. The jog
buttons increment the least significant digit by 1, 10 or 100
counts.
Software
WIKA EasyCal calibration and documentation software makes
calibrating any type of pressure instrument easy and enables
the production of calibration certificates. Customers can also
create their own test programs using the Mensor communica-
tion command set, the SCPI command set or the emulation
command set used when replacing other calibrators.
Complete testing and calibration systems
Communication with other instruments is made easy with an
IEEE-488.2, an Ethernet and a USB interface. The CPC3000 can
be integrated into an existing system, or our Custom Systems
group can design a system to meet a specific need.

Touch screen operation
Main screen
The CPC3000 main operation screen appears after powering up the unit. This screen contains all of the controls needed to
navigate within the menus and to operate the instrument. The setup icon button opens up a menu that provides navigation
to all the set up screens, limits indication, tab selectable input menu, set point display and selection, pressure value indica-
tion pressure units indication and selection and measure / control / vent mode selection.

MEASURE
Measure mode pneumatically
connects the pressure sensor directly
the device under test. In measure
mode pressure regulation is inactive,
however, if the unit is switched to
measure mode after controlling to a
set point, that pressure will be sealed
between the device under test and the
internal pressure sensor.
Optional information on the main screen
CONTROL
In the control mode, the device
regulates the pressure output accord-
ing to the set point value, providing a
precise pressure at the test port.
Input menu field (numerical/Step funct/Jog funct)
VENT
Vents the system and the device under
test to atmospheric pressure.
The menu is particularly clearly arranged and offers the option to show additional information via the SETUP menu (see

The pressure set point can be changed using one of three input modes
A) The numeric keypad
Application: direct input of set point value.
Screen with input menu: numerical
B) The Step keypad
Delete input/delete last
character/input acknow-
ledgement
Operation
The desired pressure set point value is entered using the
numeric keypad and then acknowledged by pressing the
check mark key. In control mode the controller will regulate
the output pressure to the entered value.
Application: Calibration of incremental user defined pressure points or percent of full span of the device under test.
Screen with input menu: STEP
C) The Jog keypad
Configurable via SETUP
� in % of the end value
� in the current pressure unit
Operation
Each step on the step keypad can indicate user defined
pressure values or percent of span values for the device
under test. For example: the step keypad shown to the left is
set for 10% steps going from 0% to 100%. These steps are
a percent of the user defined device under test full
span. In control mode, when a step is touched, the control-
ler will regulate the output to the associated set point.
Application: Fine adjustment of the pressure value to reach a cardinal value on a pressure gauge or similar device under test.

Operation
The triangles on the Jog keypad have values which corre-
sponds to the 3 last digits of the pressure reading and are
used to increment the set point. Triangles pointing up will
increase the value and those pointing down will decrease
it. The smallest triangle increments the least significant
digit by one, the medium size triangle increments the least
significant digit by ten and the large triangle increments
the least significant digit by one hundred. The values will
change accordingly if the resolution of the indication is
changed.
