instrument is not designed for oxygen use.

CAUTION: Avoid excessive overpressure to the sensor! Externally
mounted relief valves to provide overpressure protection are avail­able from Mensor as optional devices, and are highly recommended
for very low pressure sensors (less than 10 psi).

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

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 instru­ment 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 re­charge 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 approximate­ly one hour of battery left. The unit will automatically shut off when the battery reaches a
predetermined level.

Operating Instructions CPG2300 Series 9

Portable Digital Pressure Gauge
CPG2300 Series

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