Buttons, Labels and Windows: The CPG2500 touch screen has many buttons with relevant graphic
icons or text which, when pressed, will open a related window where changes can be made or information viewed. Some of these buttons will toggle from one state to another, others present choices or display a numerical data entry screen. Text or icons that are displayed, but do not respond to being touched,
are called labels or windows. Operators will quickly become accustomed to the particular characteristics
of the frequently used buttons.
Main Screen: The main screen or “Measure Application”, appears after power-up. This screen contains
the channel frames and settings button. It will remain as congured after a power cycle.
Transducer Channel Frame(s): The transducer channel frames (left 2/3 of the screen) contain informa-
tion specic to a channel. Up to three channels can be displayed at once, two are shown in the picture
above. The channel frames are color coded with channel A - green, channel B - blue and the remote
channel - red. The optional barometer channel is sky-blue and the delta channel is yellow. If only one
channel is installed, a full frame will be displayed in the color of the channel connected. The channel
frame contains the pressure reading, units, and mode(absolute or gauge) plus any auxiliary displays that
have been chosen.
3.5 Chassis Assembly
The chassis assembly is the housing for the system and the removable transducers. The system has no
user-serviceable parts, and therefore the chassis should not be opened except by qualied repair personnel at Mensor or certied service locations for any reason except to change the removable transduc-
ers.

Accuracy is dened by total measurement uncertainty with the coverage factor (k=2) and includes the intrinsic performance of the instrument (linearity, hysteresis, repeatability), the measure-
ment uncertainty of the reference instrument, long term stability, inuences of ambient conditions, drift and temperature eects over the calibrated range, with periodic zero point adjustment.
(2)
The Intelliscale (IS) specication is a percent of reading specication combined with a percent of full scale specication. For example the designation “0.01% IS-50”, simply means that the
uncertainty of the sensor is 0.01% of reading above 50% of Full Scale, and 0.01% of 50% of Full Scale below 50% of the Full Scale. The 0.008% IS-33 specication is the same except the
uncertainty is 0.008% and the break over from percent of reading to percent of Full Scale is at 33% of Full Scale. Same rules apply for bidirectional ranges.

Gauge and Bidirectional ranges with full scale or full span range less than 14.5 psi have a calibration interval of 180 days, otherwise the calibration interval is 365 days.

The instrument can be set up on a desk top or it can be rack-mounted. Rack mount hardware is optional
on the CPG2500 (see Section 5.2 Dimensions and Section 8, Options).
The special sensors used in the CPG2500 are relatively insensitive to tilt and vibration. However to further assure stability and accuracy, avoid mounting the instrument on surfaces subject to excessive motor
or machinery vibration.
5.4 Rear Panel
Two slots are available on the rear of the CPG2500. These slots can be lled with a removable transducer
or a remote transducer interface connection. Gauge Transducers will have a reference and a pressure
port. Absolute transducers will have a plug in the reference port. If a barometer is installed a hose barb
tting will be installed in the upper right. Transducers with analog output will have an electrical connection. Positioned on the left side is a remote transducer connection, the RS-232, Ethernet, IEEE-488, USB
device connections for communication, the USB host connection and the 12 VDC power input.

Notice
For pressure range less than 6015 psi, the pressure ports on the rear are female 7/16 - 20 SAE/MS
straight threads per MS16142 and SAE J514 table 14. Connected adaptors require a tube tting boss
seal with an o-ring per MS33656. Mensor can provide a variety of adapter ttings (see Section 8 Options) with the instrument. Do not use sealant on ttings sealed with an o-ring. The integrity of each seal
is particularly important since even microscopic leaks can cause errors in pressure measurements. For a
pressure range greater than 6015 psi, a xed Autoclave F250C/HIP HF4 tting is attached
5.4.2 Pressure Port
The CPG2500 will precisely measure the pressure connected to the pressure port up to the full scale
range of the transducer installed.
5.4.3 Reference Port
The reference port is available on gauge units that have sensors that are not sealed gauge units. For
these units this port is available to connect to the reference side of the sensor. This port is normally left
open to atmosphere but may be connected to a stable reference pressure. In an absolute pressure transducer this port is plugged.
5.5 Remote Communication Connections
See Section 7, Remote Operation, for connections and commands for operation over IEEE-488, Ethernet, USB or RS-232 ports.
5.6 Power Up
Apply power to the power connector on the rear of the instrument using the power adaptor included, and
switch the power switch on the front of the unit ON. The instrument will go through an initialization process and system check. As soon as the system check is completed the system will default to a screen
similar to the one shown in Section 6.1.2 - Display Screen Features. The main measurement screen may
be congured in many dierent ways but initially it will be in a default conguration. Subsequently, the unit
will power up in the conguration that it was in when last powered o. Allow at least 15 minutes of warm
up before performing critical pressure measurements.

CPG2500
7.5 Mensor Command Set
This Mensor command set is the default on the CPG2500. For queries (ending with a ?), the Data column
represents the response of the CPG2500. All response strings begin with a space character or an “E”
representing that there is an error in the error queue. All response strings are terminated with a <CR>
and a <LF>. The error queue holds the last 10 errors identied.
For all commands (no ?), the data column represents the required parameters to be sent to the CPG2500
following the string in the command column. For any command that requires multiple parameters to be
sent, the parameters must be separated by commas.
7.6 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 ag.
CommandorQueryeld: Unless otherwise specied, commands are typically converted to queries
by appending a question mark to the command. Table 7.9 lists all of the CPG2500 command or query
keywords.
Dataeld:The data eld is either in ASCII {string} or numeric {value} form. In the case of multiple data
elds, commas are required to separate the elds. Queries do not have a data eld. 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
7.7 CommandSetDenitions
In this manual a data entry made up of alpha characters is dened 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 dened as values.
Command: Any command or query listed in Table 7.9. For commands that take boolean data the following strings are acceptable:
0 1
False True
No Yes
O On
Separator: Space (SP).
Data: ASCII representations of numbers, {value}, or alpha characters, {string}, data as dened above.
When sending code a literal variable replaces the brackets 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-488.2 operation “EOI” is an acceptable alternative.
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 CPG2500 will return {data} terminated by CR and LF. Floating point
data is returned in the current engineering units in exponential format.

8.1 Barometer
The CPG2500 can be ordered as a single range Barometer. It is a very stable, absolute pressure sen-
sor, used to accurately measure local atmospheric pressure. The only signicant dierence between a
barometer and a regular transducer is that the transducer in a Barometer is calibrated from 8 to 17 psia
and has an accuracy of 0.01% of reading. The channel setup information as explained in this manual also
applies to the Barometer. It cannot, however, be used as a barometric reference for Gauge or Absolute
emulation.
8.2 Barometric Reference
The Barometric Reference Transducer is an absolute pressure sensor used to accurately measure local
atmospheric pressure. This sensor is in a dierent housing compared to the regular transducers. It is
removable by taking o the top cover of the chassis.
The CPG2500 uses the barometric pressure, measured by the barometric reference, for pressure mode
emulation in the internal and external transducer channels. If a barometric reference is installed the Pressure Mode button in the measure application (main screen) will become active and, when pressed, will
toggle between Absolute and Gauge mode (See section 6.4.1 Measure Application).
8.1.1 Gauge Pressure Emulation
In the Measure Application (main screen) an absolute transducer channel will indicate “Absolute” in the
mode button (this is the default mode). When this button is pressed the button label will toggle to “Gauge”
and have a lighter background color. The lighter background color is an indication that the channel is in
emulation mode.
In the gauge emulation mode the atmospheric pressure reading from the barometric reference transducer is subtracted from the absolute pressure reading of the channel to emulate a gauge pressure.
The barometric reference sensor has six signicant 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 resolution of the barometric reference.
8.2.1 Absolute Pressure Emulation
In the Measure Application (main screen) a gauge transducer channel will indicate “Gauge” in the mode
button (this is the default mode). When this button is pressed the button label will toggle to “Absolute” and
have a lighter button background color. The lighter background color is an indication that the channel is in
emulation mode.
In the absolute emulation mode the atmospheric pressure reading from the barometric reference transducer is added to the gauge pressure reading of the active channel to emulate an absolute pressure.
Operating Instructions - CPG2500 61
Precision Pressure Indicator
CPG2500
8.2.2 Emulation Mode Accuracy
The accuracy in emulation mode is the combined accuracy of the transducer and the barometric
reference.
8.2.3 Barometric Reference Calibration
The Barometric Reference Transducer can be calibrated in exactly the same manner as the other
installed sensors as described in Section 10, Calibration.
8.2.4 BarometricreferenceSpecications
Accuracy: 0.01% of reading. Uncertainties include all pressure eects, temperature eects over the
calibrated range and calibration stability for 365 days after re-zeroing.
Pressure Range: The standard Barometric Reference Transducer is calibrated from 8 to 17 psia.
Resolution: 6 digits.
8.3 Delta Channel
The Delta Channel is a virtual channel that can display an arithmetic combination of the value of any
two transducers that are installed. The Delta Channel is active when there is more than one transducer
attached. When active, the Delta Channel can be chosen in the Frames App to be displayed in the
Measure App and can be congured in the Transducer App as shown in gure 8.3. The Delta channel is
enabled automatically when more than one transducer is connected.
Figure 8.3 - Delta Channel Setup
8.4 External Transducers (CPT6100 and CPT6180)
The CPT6100 and CPT6180 are stand alone Digital Pressure Transducers that can be purchased
separately and connected to the remote transducer port on the back of the CPG2500. They can also be
connected to an external sensor package (D-Sub) (See Section 8.5 below) that has been installed in the
place of a removable transducer. The CPT6100 and CPT6180 have their own data sheets and manuals.
8.4.1 External Pressure Sensor Connection Cable
A shielded ribbon cable is required to connect an external transducer and can be supplied with or without
an external Transducer. The part number is: 4060090001.
62 Operating Instructions - CPG2500
Precision Pressure Indicator
CPG2500
8.5 External Sensor Package (D-Sub)
A plate with a D-Sub connector can be supplied with the instrument or after the initial purchase. This
plate (See picture in section 5.4 Figure 5.4 B) can be installed in the place of a removable transducer to
provide an additional connection for an external transducer (See section 8.4). When replacing a removable transducer with the plate, the internal ribbon cable that was connected to the removable transducer
should be connected to the inside connector on the plate.
8.6 Analog Output
The analog output option is available on all internal Transducers and on the CPT6100 external trans-
ducer. It can be congured at the time of manufacture to have voltage output that is directly proportional
to the pressure input.

To calibrate the internal transducers or the barometric reference remotely, use the same setup described
in section 10 of this manual. The only dierence is that the interface with the transducer is through the
software provided and a PC, not directly through the instrument.
8.9.3.1 Transducer Removal
To remove the internal transducer, rst remove the four slotted screws holding the transducer in the
chassis, slide the transducer out of the back of the chassis and unplug the ribbon cable from the back of
the transducer.
Figure 8.9.3.1 - Transducer Removal
8.9.3.2 Barometric Reference Removal
To remove the optional Barometric reference, rst remove three screws holding the top panel of the
chassis, then remove the top panel. This will reveal the barometer, Figure 8.9.3.2. The barometric
reference can be removed by removing the attached hose, loosening the thumb screw, and lifting the
barometric reference out of the chassis.

10 Calibration
The CPG2500 automatically adjusts the pressure reading for the eects of temperature and non-linearity
within the calibrated temperature range of 15-45°C. The process is referred to as dynamic compensation
because each reading is so adjusted before it is output to the display or to a communication bus. Thus, a
calibrated CPG2500 operated within its temperature band, and with proper zero and span adjustments,
will provide accurate pressure measurements.
The CPG2500 should have the calibration veried periodically to insure stability. The recommended
calibration cycle is one year or six months depending on the transducer range.
10.1 Environment
For maximum accuracy, allow the CPG2500 to warm up a minimum of 15 minutes in ambient
temperature within the compensated range prior to a calibration. In addition, the instrument should be at
rest on a stable platform that is free of excessive vibration and shock.
10.2 Pressure Standards
Mensor recommends the use of appropriately accurate primary pressure standards when calibrating
this instrument. Such standards should be sucient 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.
10.3 Media
The recommended calibration medium is dry nitrogen or clean dry instrument air. A height variation
between the standard and the CPG2500 can cause signicant errors. A calculation should be made to
compensate for this dierence.

10.4 Setup
The following illustration for calibration setup shows a typical setup for either local or remote calibration
for an absolute or gauge pressure instrument. The equipment shown in the rectangle is only necessary
for absolute calibration. The PC 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 recommended over the gauge tube type of vacuum sensor for calibrating sub-atmospheric pressures. A vacuum pump with the capacity to generate 300 millitorr is recommended.

10.8 Two Point Cal Application
The Two Point Cal Application provides a place to adjust the Transducer Zero and Span (some-
times referred to as the oset and slope).
Figure 10.8 - Two Point Cal Application
Follow the steps below for a complete 2 Point Calibration:
Select a Transducer to calibrate by pressing the Channel button at the top of the screen.
To calibrate the “low Point”:
1. The pressure port of the transducer being calibrated should be supplied with a suitable, “low point”
pressure (see section 5.4 Rear Panel for the port location).
2. For a gauge transducer, this low point pressure can be achieved by opening the pressure and reference ports to atmospheric pressure.
3. For an absolute transducer a suitable source of vacuum should be applied to the Pressure port along
with a high accuracy vacuum standard or a pressure calibration standard can be connected to the
Pressure port that can generate and measure a pressure value. In either case the pressure should
be measured at a stable value that is within 20% of the minimum range of the selected internal transducer.
4. When the pressure is stable, record the live reading shown on the Two Point Cal screen and enter this
value as the “Low Reading” by pressing the Low Reading button and entering the number followed by
the check mark [
]. Record the “true pressure” obtained from the reference standard and enter it
as the “Low Reference” value in the same manner.
To calibrate the”High Point”:
5. The “High Point” Calibration is done in a similar way as the “Low Point”.
6. Supply a pressure to the Pressure Port of the Transducer being calibrated, using a pressure standard.
This pressure should be as close as possible to the full scale value of the selected transducer or at
least within 20% of that value.
7. After the pressure stabilizes, record live reading shown on the Two Point Cal screen and enter this
value as the “High Reading” by pressing the High Reading button and entering the number followed by
the check mark [
]. Record the “true pressure” obtained from the reference standard and enter it
as the “High Reference” value in the same manner.

10.9 Linearization
The Linearize Application provides a place to record upscale and downscale calibration data
and to linearize each transducer using that data. An “as found calibration” can be performed by
connecting a suitable pressure standard to the Pressure port of the transducer being calibrated,
and supplying all 11 pressure points across the complete range. The record of the pressures
from the pressure standard and the corresponding reading from the instrument’s transducer can
be recorded and transcribed into the Linearization Matrix shown in Figure 10.9-A. Linearization
of each transducer can be performed from this screen by selecting each transducer channel
using the channel button in the top left hand corner.

The Linearization Application automatically populates the screen with 10% increments from the low to
high pressure corresponding to the range of the transducer selected. These values can be changed to
reect the values generated by the standard and the corresponding readings taken from the CPG2500.
Each value from the standard can be entered under the reference column, corresponding Upscale and
Downscale readings from the instrument can be entered in the “Upscale” and “Downscale” columns. To
enter a value simply press the number and a key pad will appear (see Figure 10.9-B) where the number
can be entered. Press the check mark [
] to accept each value. The “Average” column automatically
averages the upscale and downscale values.

10.10 Head Pressure
The Head Pressure Application provides an automated way to calculate the head pressure oset between a device being tested and the CPG2500 sensor, based on:
• The dierence in height between the device under test and the sensing element in the transducers
(internal and external) in the CPG2500
• The gas density of the pressure media
• The gas temperature
• The local gravity
The Head Pressure application is placed under the password protected area of the operator interface to
safeguard against inadvertent activation. It is intended to be used to accurately measure the pressure at
an external source that is at a dierent elevation from the CPG2500 transducer sensing that pressure.
The four parameters are used to calculate the pressure that is a result of the dierent elevations. It should
not be used when calibrating CPG2500 transducers. The Head height should be set at zero before calibrating the transducers of the CPG2500.
The Head Pressure should not be active when calibrating CPG2500 transducers.
i
Notice
The Head height should be set at zero before calibrating the transducers of the
CPG2500.DierenceinheightbetweenthelaboratorystandardandtheCPG2500
during calibration should be factored into the uncertainty analysis.
