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 recom-

mended.

Caution

CAUTION: Some ranges require clean, non-corrosive pressure

media. See “Media Compatibility” in Section 4, Specifications. 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 avail-

able from Mensor as optional devices, and are highly recommended

for very low pressure sensors (less than 10 psi).

Caution

CAUTION: It is recommended that a backup wrench be used when

installing fittings or connections on the CPG2300.

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 ground-

ed 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 CPG2300 Digital Pressure Gauge is a portable battery powered instrument that

provides very high accuracy pressure measurements. This instrument utilizes very high

stability silicon sensors that are electronically compensated for pressure linearity over

the entire operating temperature range. The CPG2300 also has a standard RS-232

serial port that can be used for remote communications.

Different models are available including the Model 2310 (single channel) and the Model

2320 (dual channel). These channels are referred to as Channel A and Channel B, and

can operate independent of each other. Viewed from the front, Channel A is the sensor

on the top left of the instrument and can be ordered with any available pressure range

(see the Specifications section). Channel B is the sensor on the top right of the instru-

ment and can be ordered with pressure ranges from 3 to 1000 psig (7.5 to 1000 psia).

Additionally, the CPG2300 can be equipped with optional current measurement from 4

to 20 mA and a 24V dc loop power. See the Options section for more information.

3.2 Display

Several different display screens are presented while operating the CPG2300. Each

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

rows. These screens are each described in further detail in the Local Operation and

Remote Operation sections.

3.3 Power Supply

The power adapter is utilized to provide power to operate the CPG2300 and also to re-

charge the internal batteries. It produces 12 Vdc @ 830 mA max.

3.4 Battery

The CPG2300 has an internal battery pack consisting of four ‘AA’ nickel-metal hydride

batteries. The battery pack is replaceable and can be ordered from Mensor.

In pressure measurement mode the CPG2300 will operate approximately 20 hours on a

fully charged new battery. There is a battery level indicator on the display that indicates

the battery charge level. The battery level indicator will blink when there is approximate-

ly one hour of battery left. The unit will automatically shut off when the battery reaches a

predetermined level.

10 Operating Instructions CPG2300 Series

Portable Digital Pressure Gauge

CPG2300 Series

Battery Charging: The CPG2300 has a built-in battery charger that will take approxi-

mately 8 hours with an input supply of 12VDC to fully recharge a battery. The built-in

charger will switch from fast charge to maintenance mode automatically when a full

charge is achieved. It is acceptable to leave the wall transformer connected to AC

power indefinitely.

Charge Voltage vs. Temperature: The battery can be charged over an ambient

temperature range of 0 to 40 degrees C with a supply voltage of 9 to 12 VDC.

3.5 Serial In/Out Communications

The serial port is configured as RS-232, 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. The serial port can be used to configure and

calibrate the CPG2300 or to read the output of its sensors.

Wiring requirements are provided in the Installation section and a list of valid commands

and responses (Table 7.2.3) is provided in the Remote Operation section.
