3. Product Description

3.1 General Description

The CPG 2500 Digital Pressure Gauge is a multi-channel pressure system designed
to test and calibrate a variety of pressure devices in either absolute or gauge pressure
modes. The CPG 2500 can have two independent measurement channels plus an op­tional barometric reference.

Figure 3.1 - Front View

3.2 Features

Here is a short list of significant features designed into the CPG 2500:

1. Up to two highly stable, temperature compensated, pressure transducers.

2. An optional internal high accuracy barometric reference transducer provides gauge

pressure emulation for all of the absolute ranges and absolute pressure emulation for
gauge ranges.

3. A color HVGA display with a touch screen for intuitive operator interface.

4. Multiple languages; change the language for on-screen text and number/date for-

mats by simply touching one of the “national flag” icons available on the display. The
current language selections available are listed in Section 6, Local Operation, under
the heading “Language selection key”.

Operate the CPG 2500 while it is either sitting on a bench or mounted in a standard
equipment rack. 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 CPG 2500 front panel includes a 6.2 inch color Half Video Graphics Array (HVGA)
liquid crystal display featuring touch screen technology. Operator input is accomplished
by pressing the words or icons presented on the display. There are no discrete keypads
or switches on the front panel.

On the lower right hand side of the front panel there are labels which show the model
number, serial number, and calibrated pressure ranges of the internal transducers.

3.4 Display

When the CPG 2500 is powered up it takes about one minute to initialize, then displays
a screen similar to the one shown in “6.3 - Display Screen Features”. The display is
made up of rectangles that display text or icons.

Keys, Tabs, Labels and Windows: In this manual a key is a small rectangle which
acts as a switch when pressed. Keys have borders with a three dimensional, shadowed
effect. Tabs are a group of touch points, each of which will overlay most of the screen
with one page related to its title subject. Small rectangles with double line borders that
display information, but do not respond to being touched, are called Labels or Win­dows.

Keys cause something to change when they are touched. Each key has a character­istic response when actuated; either an instant, single step response when the key is
pressed, or a delayed response when released. Operators will quickly become accus­tomed to the particular characteristics of the frequently used keys. Some keys become
labels under certain conditions, then resume their key function in other circumstances.

Main Screen: The main screen appears after power-up. This screen contains the chan­nel frames and toolbar.

Channel Frame(s): The channel frames contain information specific to a channel. The
channel frames are color coded with channel A being green and channel B being blue.
The Delta channel is yellow. If only one channel is installed, a wide frame will be dis­played in the color of the channel selected. The channel frame contains the channel
setup key (wrench icon), the channel title bar, the calibration function key (if enabled),
the engineering units key, the pressure reading window, and the display function win­dows/keys (if enabled).

Toolbar Keys: The toolbar at the bottom of the screen has the Contacts and Version
Information key (brings up a corporate information display), the language selection key,
the main screen view key, the remote setup key, and the remote status key.

5. Installation

5.1 Unpacking the Instrument

In addition to functional testing, each unit is inspected for appearance prior to leaving
the factory. Upon receipt, please examine the transducer for shipping damage. Report
any apparent damage to the carrier immediately.

In addition to this manual you should have:

• CPG 2500 Digital Pressure Gauge;

• Power Supply;

• 1/8 inch FNPT fitting adapters;

• Any accessories ordered;

• An envelope containing the Calibration Certificate.

5.2 Dimensions

5.3 Mounting

The instrument can be set up on a table top or it can be rack-mounted. Rack mount
adapters are optional on the CPG 2500 (see Section 8, Options).

The special sensors used in the CPG 2500 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.

Mensor/WIKA Operating Instructions Series CPG 2500 19

SERIES CPG 2500

5.4 Rear Panel

Up to five pneumatic pressure ports are located on the rear panel. Positioned between
the pressure ports are the ethernet and RS-232 connectors and the power switch. Op­tional connectors could be a GPIB connector, a barometric reference hose barb, or an
analog output connector.

5.5 Pressure Connections

When making up a connection to an o-ring adapter fitting port use a
back-up wrench to prevent over-stressing the threads in the mani-

fold block.

All of the primary 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 Sealant 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.

SERIES CPG 2500

5.5.1 Pressure Port

Connect a device to be tested to the PRESSURE port. The CPG 2500 will precisely
measure the pressure at this port up to the full scale range of the sensor.

5.5.2 Reference Port

On low pressure (< 20 psi) gauge units this port is available to connect to the reference
side of the transducer. The maximum value is equal to or less than the range of the
sensor or 20 psi, whichever is less. This port is normally left open to atmosphere but
may be connected to a stable reference pressure. It is optionally available on all gauge
ranges <= 6000 psi.

5.5.3 Remote Bus Connections

See Section 7, Remote Operation, for connections and commands for operation over
the Ethernet or RS-232 serial port.

5.6 Power Up

After the pressure connections are secure, apply power to the power connector on the
rear of the instrument and switch the power switch 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 6.3 - Display
Screen Features. Allow at least 15 minutes of warm up before performing critical pres­sure measurements.

key. When the Zero key is pressed on an absolute sensor, a number entry keypad is dis­played to allow the user to enter the applied pressure. When power is cycled the zero is
saved in the sensor through the password protected zero function (see Section 6.5.2.3 -
Adjust Tab). It will also return to the most recent factory calibrated zero when the “Reset
Factory Cal, OK” key is pressed (see Section 10.5.2 - Utility Tab). This feature must be
enabled in the Adjust settings to be available. See Section 6.5.2.3 - Adjust Tab for more
information.
