2. Safety Notices

2.1 Warnings and Caution Notices

Warning

!WARNING: NOT EXPLOSION PROOF!

Installation of this instrument in an area requiring devices rated as

intrinsically safe is not recommended.

Caution

CAUTION: Some ranges require clean, non-corrosive pressure

media. See “Media Compatibility” in Section 4, Specications. This

instrument is not designed for oxygen use.

Caution

CAUTION: Avoid excessive overpressure to the sensor!

Externally mounted relief valves to provide overpressure protection

are available from Mensor as optional devices.

Caution

CAUTION: Use of a power supply other than the one provided by

Mensor will invalidate the warranty.

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 to sensitive electronic

components.

Additional notices are found throughout this manual.

3. Product Description

3.1 General Description

The CPG2400 is the lowest accuracy single-range pressure measuring instrument

available in the Mensor CPG family. With an uncertainty of 0.03% FS, and a small

package design, this unit is perfect for desk top monitoring of pressure changes and

for use in Production and Test environments. Temperature compensation from 15 to 45

degree C permits use in this temperature range without degradation of accuracy.

The unique design of the CPG2400 has modest features and simple menu options. It

has a standard RS-232 serial output port that can be used for remote communications.

It can display measured pressure along with peaks or null. Other features are a mono-

chrome LCD display, null capability, a single silicon sensor and it is powered by a wall

transformer.

Optional features include external dual differential relief valves, externally mounted relief

valves, RS-485 communications (100 ft cable length recommended), and a rack mount

kit.

3.2 Display

Several different display screens are presented while operating the CPG2400. Each

screen is arranged into blocks of information, generally organized into columns and

rows. These screens are each described in further detail in Section 6, “Local Opera-

tion”, and in Section 7, “Remote Operation”.

3.3 Power Supply

The power adapter is utilized to provide power to operate the CPG2400. It produces 12

VDC @ 830 mA max.

3.4 Serial In/Out Communications

The serial port can be used to configure and calibrate the CPG2400, or to read the out-

put of its sensor. Depending on how your CPG2400 was ordered, the instrument came

with either RS-232 or RS-485 serial port communications. Both are explained below.

The RS-232 serial port is configured as 9600 baud, 8 data bits, 1 stop bit and no parity.

It is designed as a 9-pin DCE device so that a straight pin to pin cable can be used to

connect it to a standard PC serial port.

Digital Pressure Gauge

CPG2400 Series

The RS-485 serial port is configured for 4-wire plus ground connections. The port

operates at 9600 baud, 8 data bits, 1 stop bit and no parity. The device address can

be changed using a remote command. When connecting several units in a multi-drop

configuration, it is recommended that the cable length be limited to 100 ft.

Wiring requirements are provided in Section 5.4, “Electrical Connections”, and a list of

valid commands and responses is provided in Section 7.2.5, “Commands and Queries”.
