3. Product Description

3.1 General Description

The Mensor CPC 6000 Automated Pressure Calibrator is a multi-channel/multi-range pressure system
designed to test and calibrate a variety of pressure devices in either absolute or gauge pressure
modes. The CPC 6000 can have two independent control channels each with its own pressure
regulator. Each control channel can have up to two transducers. Transducers can be of two types:

“Intelliscale Transducers” (IS) or “Turndown Transducers” (TD).
Intelliscale Transducers (IS) have an accuracy of 0.01%Intelliscale-50 (0.01%IS-50). This specification

is a percent of reading specification with a 365 day calibration stability and is explained in
this manual

. The 0.01%IS-50 specification is available in all new CPC 6000’s and applies to full scale
ranges above 15 psi absolute or gauge. CPC 6000s with software version 1.25 and below require a
software upgrade to version 1.26 or greater to be able to communicate with Intelliscale Transducers.

Turndown Transducers (TD) can have two ranges configured on each transducer. These ranges are
referred to as turndowns and each one has an uncertainty of 0.01%FS with a calibration stability of
185 days. The second (lower span) turndown cannot have a span that is less than 50% of the primary
turndown span. Turndown Transducers can be used in all CPC 6000 sofware versions.

Below is a software version comparison matrix.

3.2 Features

Here is a short list of significant features designed into the CPC 6000:

1. 0.01%Intelliscale-

50 Uncertainty.

2. Up to four (two per channel) highly stable, temperature compensated, pressure transducers.

3. An optional internal high accuracy barometric reference transducer provides gauge pressure emula
tion for all of the absolute ranges and absolute pressure emulation for gauge ranges;

4. All pressure transducers are individually removable from the front of the CPC 6000 without the use
of tools (excluding the barometric transducer). This feature greatly facilitates “out of instrument”
recalibration of individual transducers using the optional Calibration Sled (see

Section 8, Options);

5. Two precision pressure regulators are selectable for controlled output pressure. These regulators
have a history of excellent control and stability;

6. A separate electrical module using a high speed microprocessor. The operating program is loaded
from a non-volatile flash disk;

7. A large color SVGA LCD display with a touch screen for intuitive operator interface;

8. Multiple languages; change the language for on-screen text and number/date formats instantly by
simply touching one of the “national flag” cues available on the display The current language selec
tions available are listed under ‘

6.3.2 - Flag Symbol ‘in Section 6, Local Operation.

Operate the CPC 6000 while it is either sitting on a bench or mounted in a standard equipment rack.
Leveling the instrument is not a consideration since the pressure sensors are not affected by orienta

­tion. Use either front panel input (Local Operation), or send commands and queries over a bus from a
separate “host” controller (Remote Operation).

3.3 Front Panel

-

-

The CPC 6000 front panel (Figure 3.2) includes an 8.4 inch color SVGA display featuring touch screen
technology. Operator input is accomplished by pressing the words or symbols presented on the dis

-

play. There are no discrete keypads or switches on the front panel.
On the right hand side of the front panel, there is a clear window which shows the calibrated pressure

ranges of the internal transducers and the instrument serial number.
To gain access to the internal modules simply loosen the two thumb screws on the right hand edge of

the front panel and swing it open (Figure 3.3). In the front of the instrument directly below the electrical
module are slots to accommodate two pressure transducer modules on each control channel. Each
transducer can be removed and reinstalled through the front panel opening. See Section

9.3.1, Trans-

ducer Removal, for additional information on module removal and replacement.

3.6 Pneumatic Module

Pneumatic modules come in two types and are referred to in this manual as the “Pump Regulator”
or the “Solenoid Valve Regulator”. The pump regulator is used with low pressure sensors specified

Section 4, Specifications. The solenoid valve regulator is used with higher pressure sensors and

in
comes in three varieties:

■

High Pressure Solenoid Valve Regulator (HP SVR)

■

Medium Pressure Solenoid Valve Regulator (MP SVR)

■

Low Pressure Solenoid Valve Regulator (LP SVR)

Pressure limits for all of these are specified in Section 4, Specifications.

Each pneumatic module (Figure 3.6) includes platforms for up to two high performance pressure trans
ducers which are traceable to NIST standards. Both of these transducers can be used in conjunction
with the highly stable pressure regulator to produce a precise pressure output. Each transducer in

­cludes its own on-board compensation and calibration data so that any transducer can be replaced in
the instrument without requiring a recalibration.

3.7 Chassis Assembly

The chassis assembly acts as the housing for the system. The electrical and pneumatic modules are
each self-contained inside the chassis, and either can be replaced using basic hand tools. In addition,
each pressure transducer is individually removable without tools. Instructions for transducer and mod
ule removal are provided in

The only moving parts in the CPC 6000 are the fan, the pneumatic flow controller diaphragms and
valves, the pump/motor, and the solenoid valve plungers. There are no internal user adjustments or
setup switches.

Notice

All of the pressure ports on the rear are female 7/16 - 20 SAE/MS straight threads per MS16142 and
SAE J514 table 14. They require a tube fitting boss seal with an o-ring per MS33656. Mensor provides
female 1/8” NPT adapter fittings with the instrument. The pressure connections can be made to these
adapters with the proper mating hardware. We recommend the use of either Loctite® Hydraulic Seal
ant or new teflon tape on the threads of any male pipe fitting. Do not use sealant on fittings sealed
with an o-ring. The integrity of each seal is particularly important since even microscopic leaks can
cause errors in pressure measurements. The rear panel connections and a complete pneumatic sche
matic, including the optional secondary transducer, are provided in the
Figures 9.2.1C and 9.2.2B). Requirements for connecting to the ports on the CPC 6000 manifold are

Rate: A rate (slewing speed) which best suits the user’s test requirements is selected here. The [Slow]

rate will use internal pressure generation without the use of the roughing supply and exhaust valves.
Use this mode if no external supply or exhaust pressures are applied to the selected pressure control
channel. The [Fast] rate utilizes the roughing supply and exhaust valves.

External Volume: If the autotune is turned on, the external volume of the controlled system is calcu­lated automatically for optimum control performance. If the external volume is known, the user can
press the external volume key and enter the volume. Subsequently, if [Autotune] is turned off, the
control channel will not re-calculate the external volume on each control setpoint change which will
decrease the control times.

Autotune: If the autotune key is turned on, the control channel automatically calculates the external
system volume for optimum performance on each control setpoint change.

[Test] key: is used to enter a test mode that gives the user individual control of all solenoids. This is
further described in

6.8 Solenoid Valve Regulator

Control Limits: The control limits cannot be set outside the maximum or minimum ranges of the

transducers installed on the active channel. To change a limit touch either of the [Limit Value] keys and
enter the new value.

Rate: A rate (slewing speed) which best suits the user’s test requirements are selected here. The rates

vary the pressure slew rate while driving to a pressure setpoint. The [Slow] rate will target approxi
mately .1% of the highest installed range/second. The [Medium] rate will target approximately 1% of
the highest installed range/second. The [Fast] rate will target approximately 10% of the highest in
stalled range/second.

Variable rate allows the customer to enter the desired rate that the controller will approximate in the
current units/second.

Low Overshoot check: If this is checked, the control channel will minimize pressure overshoot when
driving to a new control setpoint.

Reference Vacuum check: ONLY AVAILABLE ON GAUGE UNITS! If checked, customers may pump
the reference port to achieve absolute emulation.

[Precision] key: If this key is selected, parameters are loaded into the active channel so that it will
operate with minimum overshoot and maximum stability. This changes the control stable window to

0.003% of the active sensor turndown and the stable delay to 4 seconds.

High Speed] key: If this key is selected, parameters are loaded into the active channel so that it will
operate in a high control speed mode. This changes the control stable window to 0.006% of the active
sensor turndown and the stable delay to 1 second. It also changes the way the controlled pressure ap
proaches the setpoint to minimize the time to stable.

10/100Based-T specifications.

CAUTION: Please consult your Computer Resources Department prior to connect-

!

Caution

Ethernet communications are transmitted over a standard RJ-45 cable.

Connecting directly to a PC requires a crossover ethernet cable. Hub connection requires a straight
ethernet cable.

Prior to first time use of ethernet communication, the four parameters, IP, Netmask, Gateway, and Port
must be setup. These are set up in the Remote setup screen.

ing this instrument to your network to verify there are no conflicts with existing IP
addresses.

7.3 IEEE-488 (GPIB)

The manufacturer of the host IEEE-488 interface board provides software to allow communication be
tween the board and various programming languages. An interactive program for debugging is usually
provided as well. Refer to the board manufacturer’s documentation for more information.

7.3.2 Interface Functions

The CPC 6000 responds to the following IEEE-488 interface functions:

SRQ Service Request: A service request is asserted whenever an error is encountered. When

the bus controller issues a serial poll the error will be cleared. If the host IEEE board in

­cludes automatic serial polling capability, turn this feature off in order to view all errors (see
ERROR? command).

LLO Local Lockout: The front panel keyboard of the CPC 6000 may be locked by sending LLO

or the command LOCK ON.

GET Group Execute Trigger: When this message is received, the CPC 6000 will save the current

readings until the next time it is addressed as a talker.

GTL Go To Local: A GTL message will cause the CPC 6000 return to local operation and unlock

the keyboard.

DCL Device Clear: When this message is received, the CPC 6000 will clear all errors and buffers

and remain in the REMOTE mode.

SDC Selected Device Clear: The effect is the same as DCL.
EOI End or Identify: May be used as a command or query terminator in the place of, or concur-

rent with, a terminating linefeed.

7.4 RS-232 Serial Communication

The serial communication port allows the CPC 6000 to communicate in RS-232 format with comput
ers, terminals, PDAs, or similar hosts.

-

7.4.1 Cable Requirements

RS-232 communications are transmitted over a three conductor, shielded cable terminated in a stan
dard DB9S connector on the instrument end, and usually the same connector on the host end. Figure

7.4.1 illustrates the proper pin-outs. Notice that each pin 2 is connected to pin 3 on the opposite end.
This configuration is commonly referred to as a 9-pin null modem cable.

Figure 7.4.1 - Serial Cable

7.4.2 Command and Query Format

Commands must be sent in ASCII format and terminated with either a carriage return (<cr>), linefeed
(<lf>) or both. Commands are not case sensitive. Each query returns a response. If an error is detected
the response will include an error flag.

One of the first commands issued when starting remote communications should be “Keylock Yes”.
This will disable the on-screen keys and tabs, and place the “Keylock” label on the screen. Turning
keylock on prevents the potential conflicts that could occur if someone pressed an on-screen key,
either intentionally or by accident.

Command/Query Field: Unless otherwise specified, commands are typically converted to queries by
appending a question mark to the command. Table 7.4.5 lists all of the CPC 6000 command/query
keywords.

Data Field: The data field is either in ASCII {string} or numeric {value} form. In the case of multiple
data fields, commas are required to separate the fields. Queries do not have a data field. String (text)
or value (numeric) data are acceptable in any of the following formats:

Examples of {string} data: ON OFF mBar inHg
Examples of {value} data: 1 1.0 -5.678 25.68324e-5

7.4.3 Command Set Definitions

In this manual a data entry made up of alpha characters is defined as a string, as opposed to data
containing only numbers, such as “Enter 1 for ON or 0 for OFF” where 1 and 0 are defined as values.

Command: Any command or query listed in Table 7.4.5.

Separator: Space (SP).

Data: ASCII representations of numbers, {value}, or alpha characters, {string}, data as defined above.

When sending code a literal variable replaces the braces and the enclosed character(s) shown in the
following examples.

Termination: Linefeed (LF) or carriage return (CR) is used to signal the end of a command statement.
For IEEE-488 operation “EOI” is an acceptable alternative.

Mensor/WIKA Operating Instructions - CPC 6000 49

Automated Pressure Calibrator
CPC 6000

Always send commands in one of the following formats:

1. [Command] [Termination];

2. [Command] [Separator] [Data] [Termination];

3. Queries are special instructions in the form:
[Command?] [Termination] where the question
mark, “?”, immediately precedes the terminator.

When a valid query is received, the CPC 6000 will return {data} terminated by CR and LF.

Floating point data is returned in the current engineering units in exponential format.

7.4.4 Output Formats

Pressure readings are returned in exponential notation in a format according to the OUTFORM com
mand as follows:

1. <sp> pressure value <cr><lf>

2. <sp> pressure, units number, mode <cr><lf>

3. <sp> pressure, pressure rate <cr><lf>

4. <sp> pressure, minimum peak, maximum peak<cr><lf>

5. <sp> pressure, active sensor (P or S), active turndown (1-4)<cr><lf>

6. <sp> pressure, control point, “stable” or “slewing”<cr><lf>

7. <sp> pressure, “no barometer” or baro reading <cr><lf>

The space <sp> at the beginning of the string is replaced with an “E” if the CPC 6000 has detected a
remote communication error.

For commands that take boolean data the following strings are acceptable:

0 1
False True
No Yes
Off On

7.4.7 Remote Emulation

The Mensor PCS 400 is an earlier generation instrument similar to the CPC 6000. There is some
compatibility between the CPC 6000 and a PCS 400 in that the CPC 6000 will respond to many of the
remote instructions as if it were the older instrument. The PCS 400 commands will operate only on the
currently active control channel.

Table 7.4.7.1 is a list of the remote commands and queries which the CPC 6000 will recognize and
respond to.

A space between elements in a command indicates a required delimiter. Use a space where such a
delimiter is indicated. A full description of the syntax and use for each of these commands and queries
are presented in the PCS 400 manual.

All pressure values will be in the currently active pressure units

8. Options

This section lists options available for the CPC 6000. Users might consider letting the factory install
a special feature not listed here. Mensor welcomes the opportunity to quote on such requests. The
cost of adding an enhancement frequently will amortize itself in a very short time because of improved
process efficiency.

8.1 Transport Case (PN 0011159001)

A wheeled transport case is available suitable for moving the CPC 6000 between sites, or as an air­freight (or other) shipping container. The case is constructed of a high impact plastic with a black
exterior. It includes two keys, locks, a piano hinge, an anodized interlocking tongue and groove open
ing, various nickel-chrome and stainless steel fixtures, a vinyl satchel style handle and a retractable
pull-out handle. The interior is filled with high density polyurethane foam with a die-cut cavity to cradle
the instrument with fitting adapters in place, and an additional cavity to store related accessories.
Rugged and weather resistant, the case makes an attractive, practical shipping and moving container.
The case weighs approximately 29 pounds (13.15 kg) unloaded, and can support a load of up to 150
pounds (68.04 kg). Nominal dimensions are 15 inches by 24 inches by 26 inches (38.10 cm x 60.96 cm
x 66.04).

8.2 Rack Mount Kit

A rack mount kit allows the customer to in
stall a CPC 6000 into a standard 19” instru
ment rack. It includes pre-installed brackets
on the sides of the instrument as well as
spacer panels and hardware to rack mount
the CPC 6000.

Mensor/WIKA Operating Instructions - CPC 6000 71

8.3 Calibration Sled Kit

The calibration sled allows customers to cali
brate transducers outside the CPC 6000. This
allows the customer to continue using the other
ranges inside the CPC 6000, while calibrating
one of the transducers in order to reduce down
time. The calibration sled kit includes the serial
interface software, the calibration sled, a serial
cable to connect the sled to the host computer,
and a power supply (not pictured) for the cali
bration sled (see Figure 8.3).

8.4 Additional Transducers

A secondary transducer of any standard range, with up to two turndown ranges, can be purchased as
an option. In all other regards, the add-on transducer will meet all of the specifications and operating
parameters outlined throughout this manual.

Each control channel has pressure control limits. Typically, the pump regulator
modules have a maximum limit of 15 psig and the solenoid valve regulator mod-

!

Caution

ules have limits of 50-150 or 1500 psig. If a sensor is placed into a control channel
where the sensor has a higher upper pressure range than the control module, the
maximum control limit will be limited to the maximum range of the control module.

-

-

-

Figure 8.3 - Calibration Sled Kit

While any sensor will function in any control channel, the results may not always be optimum. For
example, if a 1 psi sensor is placed in a control module that has a 1500 psi upper limit, the controlled
pressure stability may not be acceptable. Or if a 1500 psi module is placed in a control module that
has a 30 psi upper limit, it will control very well, but be limited in resolution.

8.4.1 Secondary Transducer Installation

If the add-on transducer is of a higher full scale range than the existing primary transducer, then this
newer transducer becomes the Primary, and the existing transducer must be moved to the Secondary
Transducer berth. For complete installation instructions see the text under “Transducer Replacement”

Section 9, Maintenance.

8.5 Barometric Reference Transducer

The Barometric Reference Transducer is a very stable, absolute pressure device used to accurately
measure local atmospheric pressure.

The CPC 6000 will use the barometric pressure measured by the installed barometric reference sensor
in the current channel. If only one barometric sensor is installed, its measurement is shared by both
channels.

72 Mensor/WIKA Operating Instructions - CPC 6000

8.5.1 Gauge Pressure Emulation Key

Automated Pressure Calibrator

CPC 6000

On absolute units set the CPC 6000 for gauge pressure measurement and control by touching [Pres

­sure Units] which will display the Units pop-up window shown in Figure 6.3.6. In the upper right corner
of this window is an [Absolute/Gauge] toggle key. Press [Absolute] to change to [Gauge], then press
[OK]. The operation screen now shows Units [GE] in place of Units [A]. The “GE” indicates that the
measurement and control values are in Gauge Emulation pressure units.

In the Gauge Emulation mode the atmospheric pressure reading from the barometric reference trans

­ducer is subtracted from the absolute pressure reading of the active channel to emulate a gauge pres
sure.

The barometric reference sensor has six significant digits. If a very low pressure gauge sensor is active
and is used in absolute emulation, the combined output may appear quite noisy because of the reso

-

lution of the barometric reference.

Emulation mode uncertainty is the combined uncertainty of the barometric reference transducer and
the active transducer.

8.5.2 Absolute Pressure Emulation Key

On gauge units set the CPC 6000 for absolute pressure measurement and control by touching [Pres

­sure Unit] which will display the Units pop-up window. In the upper right corner of this window is an
[Absolute/gauge] toggle key. Press [Gauge] to change to [Absolute], then press [OK]. The operation
screen now shows Units [AE] in place of Units [G]. The “AE” indicates that the measurement and con

-

trol values are in absolute emulation pressure units.

-

In Absolute Emulation mode the atmospheric pressure reading from the Barometric Reference Trans
ducer is added to the gauge pressure reading of the active channel to emulate absolute pressure.

8.5.3 Calibration

The Barometric Reference Transducer can be calibrated in exactly the same manner as the other in
stalled sensors as described in

Section 10, Calibration.

-

8.5.4 Specifications

Accuracy: 0.01% of reading. Uncertainties include all pressure effects, temperature effects over the
calibrated range and calibration stability for six months after re-zeroing.

Pressure Range: Calibrated from 11 to 17 psia.
Resolution: 6 digits.

8.6 Virtual Delta Channel

8.6.1 Delta Functions

Two virtual delta functions are available: A-B and B-A. The delta functions are strictly a mathematical
difference between the two physical channel readings. There is no pressure connection between the
channels.

-

Mensor/WIKA Operating Instructions - CPC 6000 73

Automated Pressure Calibrator
CPC 6000

8.6.2 Screen Source

The CPC 6000 has two frames in which channel information can be displayed. The frame channel
source can be programmed to A(left) B(right) or A(left) Delta(right) or Delta(left) B(right). Either frame
can be minimized as before.

8.6.3 Configure Button

In order to allow the delta function and frame channel source to be changed, a new button was added
to the lower toolbar. This button is labeled ‘Configure’ and only appears when the Delta function is
enabled. Pressing this button brings up a window with radio buttons to select the desired configura
tion as shown in Figure 8.6.3.

-

Figure 8.6.3 - Configure Button Display Screen

8.6.4 Slave Channel Display

Since the range information is not applicable to the delta channel, the slave channel (the physical one
not displayed) reading is displayed where the range droplist appears in the normal screen.

8.6.5 Screen Source A B

Channels are completely independent. Operates just like a standard CPC 6000.

A is displayed on the left and is the leading channel. Delta is displayed on the right and is either A-B
or B-A as selected. Channel B’s reading is displayed where the range information normally appears on
the Delta channel. Channel B is the slave channel. Whenever the A channel is changed, the B channel
setpoint is changed to maintain the differential setpoint displayed on the Delta channel. Whenever the
Delta channel setpoint is changed, the B setpoint is changed as well.

8.6.7 Screen Source Delta B

Delta is displayed on the left and is either A-B or B-A as selected. B is displayed on the right and is the
leading channel. Channel A’s reading is displayed where the range information normally appears on
the Delta channel. Channel A is the slave channel. Whenever the B channel is changed, the A channel
setpoint is changed to maintain the differential setpoint displayed on the Delta channel. Whenever the
Delta channel setpoint is changed, the A setpoint is changed as well.

Mensor/WIKA Operating Instructions - CPC 6000 75

Automated Pressure Calibrator
CPC 6000

8.6.8 Delta Control Limits

The default control limits for the Delta channel are the maximum limits possible. Certain combinations
of setpoints will generate an illegal setpoint on the slave channel. Note that whether or not the setpoint
is illegal is dependent on the measured reading of the leading channel. In order to prevent the CPC
6000 from rejecting control points that may become legal in the future, all possible setpoints are al
lowed unless restricted by setting the control limits to other values.

8.6.9 Delta Units Type

The delta units type is Differential and a D appears after the units label. Emulation is not available on
the delta channel. If channel A and B are not set to the same pressure type, the delta reading may be
ambiguous.

8.6.10 Setup Screens

The delta channel does not have the following setup buttons: STATUS, CAL, TEST, CONTROL CAL,
control parameters except limits and stable. To change parameters on the slave channel, you must
select the A,B (normal) screen source.

Caution

9.2.1 Pump Regulator

The CPC 6000 has two Controller test screens; one is for the Pump Regulator (see Figure 9.2.1A) and
the other is for the Solenoid Valve Regulator (see Figure 9.2.2A).

To get to the test screen press [Setup], [Controller], and [Test]. The pump regulator test screen allows
control of the solenoid valves directly by the operator. Pressing the key labeled [Closed] or [Open] will
toggle the associated solenoid between the open and closed states. As each key is pressed the key
will change text and color, and the target solenoid will
make an audible “click”. If a key changes color
without the accompanying click it is an indication of a
defective solenoid or a bad connection. Pressing the
[+] or [-] key will actuate the pump and increase or
decrease the system pressure respectively. The
[speed] key allows adjustment of the relative rate at
which the pump operates to increase or decrease
pressure. The [%] key allows an adjustment of the
duty cycle of the supply and exhaust valves. The
Primary and Secondary labels show the pressure
sensed at the respective transducers. The Rate [psi/
sec.] label indicated the rate of change of the system
pressure. See Figure 9.2.1B for the pump regulator
pneumatic module. See Figure 9.2.1C for the pneu
matic schematic for the pump regulator.

9.2.2 Solenoid Valve Regulator

The Solenoid Valve Regulator test screen (figure 9.2.2A) allows control of the solenoid valves directly
by the operator. Pressing [Closed] or [Open] key will toggle the associated solenoid between the open
and closed states. As each key is pressed the key will change text and color, and the target solenoid
will make an audible “click”. If a key changes color without the accompanying click it is an indication
of a defective solenoid or a bad connection. The
[+], [++], and [+++] represent the fine, medium
and course regulator supply valves respectively.
The [-], [--], [---] keys represent the fine, medium
and course regulator exhaust valves respectively.
Applying a continuous touch to any of these keys
will open the respective regulator valve and in
crease or decrease the system pressure. The [%]
key (top left) allows a collective adjustment of the
duty cycle of the regulator valves to adjust the
flow rate through the regulator. The Primary and
Secondary labels show the pressure sensed at the
respective transducers. The Rate [psi/sec.] label
indicated the rate of change of the system pres
sure. See Figure 9.2.2B for the pneumatic sche
matic for the solenoid valve regulator.

3. Press [Setup] [Controller] [Tune] on the channel you wish to tune.

4. Press the box to the right of the Setpoint and enter 50.00 and [OK].

5. |Push the [Control] button and watch the value in the box to the right of Reading climb towards the

setpoint.

6. If the Reading stays below the Setpoint increase the Supply value by .1 until the setpoint is

reached.

7. Again press the box to the right of Setpoint and enter 25.00 and [OK].

8. If the Reading stays above the Setpoint increase the Exhaust value by .1 until the setpoint is

reached.

9. Return again to the Setpoint of 50 by repeating step 4.

10. Evaluate the way the reading reacts when approaching the setpoint and repeat steps 6 and 8 until

the desired result is reached.

11. When you are satisfied with the performance of the regulator, press the [Save] button to store the

changes you have made to the regulator. These values are stored in nonvolatile memory on the
regulator and they will be saved through power cycles.

9.3 Replacing Modules

CAUTION: ESD PROTECTION REQUIRED. The proper use of grounded work
surfaces and personal wrist straps are required when coming into contact with
exposed circuits (printed circuit boards) to prevent static discharge damage to
sensitive electronic components.

2. Loosen the two captive screws on the front panel (Figure 3.3), and swing the panel open.

3. Unscrew the thumb screw holding in the transducer (Figures 9.2.1B and 9.3.1).

4. Apply a light inward pressure against the bottom of the transducer case, just below the range label,

while tilting the case upward to clear the clamp plate and screw head.

5. Pull the transducer module outward, through the front opening.

CAUTION: There must be a transducer installed in the “Primary Transducer” berth

Caution

for the system to function properly. If the system is operated with the primary
berth empty the results will be unpredictable.

Removing a transducer disengages the electrical and pneumatic connections and seals off the pres
sure on the pneumatic module. This permits the CPC 6000 to be turned on with the supply pressure
connected even with no transducers installed.

Each control channel has pressure control limits. Typically, the pump regulator
modules have a maximum limit of 15 psig and the solenoid valve regulator mod-

i

Notice

While any sensor will function in any control channel, the results may not always be optimum. For
example if a 1 psi sensor is placed in a control module that has a 1500 psi upper limit, the control
stability may not be acceptable. Or if a 1500 psi module is placed in a control module that has a 30 psi
upper limit, it will control very well, but be limited in resolution.

where the sensor has a higher upper pressure range than the control module, the
maximum control limit will be limited to the maximum range of the control module.

CAUTION: When transducers are
replaced and the unit is rebooted, the
default parameters will be loaded. If
you are using custom settings they
must be reloaded after transducer
installation.

CAUTION: Do not install a high

10. Calibration

10.1 General

Automated Pressure Calibrator

CPC 6000

The CPC 6000 automatically adjusts the pressure reading for the effects of temperature and non-lin
earity within the calibrated temperature range of 15-45°C. The process is referred to as dynamic com
pensation because each reading is so adjusted before it is output to the display or to a communication
bus. Thus, a calibrated CPC 6000 operated within its temperature band, and with proper zero and
span adjustments, will provide accurate pressure measurements.

10.2 Environment

For maximum accuracy, allow the CPC 6000 to warm up for a minimum of 15 minutes in an ambient
temperature within the compensated range prior to commencing a calibration. In addition the instru
ment should be at rest on a stable platform that is free of excessive vibration and shock.

10.3 Pressure Standards

Mensor recommends the use of appropriately accurate primary pressure standards when calibrating
this instrument. Such standards should be sufficient so that when the techniques of the ISO Guide to
the Expression of Uncertainty in Measurement (GUM) are applied, the instrument meets its accuracy
statements as required by ISO/IEC 17025:2005, or other applicable standards.

10.4 Media

The recommended calibration medium is dry nitrogen or clean dry instrument air. A height variation
between the standard and the CPC 6000 can cause significant errors. See “
rection” for further information.

10.5 Calibration Setup

Figure 10.5 - Calibration Setup illustrates a typical setup for either local or remote calibration for an
absolute or gauge pressure instrument. In the illustration the ‘Optional Computer’ is required only for
performing a remote calibration.

The ‘Pressure Standard’ is normally a deadweight test instrument, and the ‘Volume Controller’ refers to
a hand operated variable-volume pressure vernier device. A diaphragm type vacuum gauge is recom
mended over the gauge tube type of vacuum sensor for calibrating sub-atmospheric pressures (see
Figure 10.5 under “Setup for Absolute Pressure”). A vacuum source with a capacity of generating 600
millitorr is recommended.

7. When satisfied that the new password is correct, and a written copy has been stored, press [OK]

to complete the entry. The previous password is immediately replaced by the new one.

8. Confirm that the new password is valid by pressing [Main], then repeat steps 1 through 3 to return

to the Calibration Data screen (Figure 10.6.1C). If this screen can’t be accessed using either the old
or the new password contact Mensor.

10.7 Restoring a Mensor Calibration

The offset and slope values established for each turndown at the final factory calibration are stored in
permanent memory within each transducer. These factory values can be restored at any time regard
less of the number of subsequent calibrations. To restore the factory calibration to the active turn
down, press [Restore Factory Cal] on the unlocked Data Entry screen seen in Figure 10.6.1C. This will
restore both the factory zero offset and slope calibration values to the active turndown. The [Restore
Factory Cal] function can be repeated for each turndown as desired.

10.8 On-site Calibration

-

-

The CPC 6000 can contain one primary transducer and barometric reference and may have an addi

­tional, secondary transducer. Each transducer (except the Barometric Reference Transducer) can have
up to two separately calibrated ranges (two turndowns). Zero and span adjustments are available for
each of these turndowns.

Linearity is preset at the factory and is not adjustable. One and two point calibrations are used to
make a linear correction to the pressure readings using the formula: (uncorrected reading) X slope) +
offset. The one point calibration adjusts the offset, the two point calibration adjusts both the offset and
the slope.

10.8.1 CPC 6000 Preparation Procedure

The following is a step-by step instruction for calibrating a selected turndown.

Evacuate the pressure transducer(s) to a low pressure that will still maintain a viscous flow, typically
600 millitorr (0.0116 psi). At pressures lower than this the pressure at any particular point in the sys

­tem is questionable. Allow from five to ten minutes for the target pressure to stabilize, then convert the
millitorr reading to an equivalent instrument reading in the active measurement units. Table 11.3 in the

Appendix Section lists millitorr conversion factors.

To begin a calibration, press the [Calibrate] tab and unlock the calibration screen as described in the
previous section. Select the turndown to calibrate from the drop list and the units in which to perform
the calibration on the unlocked calibration data screen.

10.8.2 [Calibrate] Setup Key

The Calibration screen shown in Figure 10.8.2A is the first of several screens relating to the calibration
functions. This screen allows the user to perform any of the following tasks:

1. Calibrate zero and span values on any turndown open of all installed sensors. An Absolute CPC

6000 allows calibration of the barometric reference transducer;

2. Establish a new Date of Calibration (DOC) for any turndown;

3. Change the system password;

4. Autozero all turndowns at one time.

Notice the padlock icon on the display. This signifies that the indicated values on the screen are not
able to be modified until the password has been entered.

[Unlock] Key: Touch [Unlock] (Figure 10.8.2A) to move on to the password screen. This function is
password protected. Details on this function are included in the

Calibration section.

[Autozero] Key: Press this key to have the CPC 6000 automatically re-zero all turndowns that can
measure the vented pressure (Figure 10.8.2C).

Figure 10.8.2C - [Autozero] Key Figure 10.8.2D - Autozero Window

For an absolute CPC 6000, this automatic function will:

1. Vent the system.

2. Select the turndown with the smallest span that can measure the vented pressure, or read the inter

nal barometric reference if installed.

3. Record that pressure as “current barometric pressure”.

4. Adjust the zero offset of each turndown so the turndown’s output equals the “current barometric

pressure”.

10.8.4 2-Point Calibration

A two-point calibration adjusts both the offset and the slope of the active turndown. The low point
must be within 20% of the minimum range of the active turndown and the high point must be within
20% of the maximum range of the active turndown. Insure that the head correction is adjusted prop
erly, see
as shown in Figure 10.8.4A. The ‘Low Point Cal’ window illustrated in Figure 10.8.4B will appear. This
window shows the maximum and minimum acceptable values and the current reading. The [?] key
