Mensor, this warranty does not apply. The judgment of Mensor will be final as to all matters con- cerning condition of the product, the cause and nature of a defect, and the necessity or manner of repair.
Notice Mensor and its suppliers shall not be held to any liability for any damages suffered or incurred by the end user (including, but not limited to, general, special, consequential or incidental damages including dam- ages for loss of business profits, business interruption, loss of business information and the like), arising from or in connection with the delivery, use or performance of the software program.
Extreme care must be taken with pressure connections when using hazardous or toxic media. Repairs must only be performed by authorized service personnel. Additional safety notices are found throughout this manual. Notice Operating Instructions - CPG2500...
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.

The CPG2500 Precision Pressure Indicator is a multi-channel pressure indicator designed to test and calibrate a variety of pressure devices in either absolute or gauge pressure modes. The CPG2500 can have two independent internal transducers, an optional barometric reference and an external remote pressure transducer.
CPG2500 Turning On You can confirm that your CPG2500 is operational right now. Apply power to the power connector on the rear of the instrument with the included power adapter, remove any plastic plugs from the rear panel pressure ports, and press the power switch to ON. The system will go through an initialization process, which takes about 45 seconds, and then a display will appear similar to the screen shown below.
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 qualified repair per- sonnel at Mensor or certified service locations for any reason except to change the removable transduc- ers.
ISO Guide to the Expression of Uncertainty in Measurement (GUM). The calibration program at Mensor is accredited by the American Association of Laboratory Accreditation (A2LA) as complying with both the ISO/IEC 17025:2005 and the ANSI/NCSL Z540-1-1994 standards. If there is an exception to the requirements and recommendations of Z540 during a calibration the excep- tion is noted on the individual calibration certificate.

Rear Panel Two slots are available on the rear of the CPG2500. These slots can be filled 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. In the upper right corner is a hose barb fitting which is connected to the baro ref if installed.
MS16142 and SAE J514 table 14. Connected adaptors require a tube fitting boss seal with an o-ring per MS33656. Mensor can provide a variety of adapter fittings (see Section 8 Op- tions) with the instrument. 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.

• Remote calibrations sleds (transducers, Barometric reference) 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 significant difference 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 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.
A cable / power supply and software are available to remotely calibrate the internal transducers outside of the CPG2500. In both cases a PC with a serial connection is required. Both kits are supplied with an instruction manual.
Figure 8.9.1 - Remote Calibration Kit for Internal Transducer 8.9.2 Barometric Reference Calibration Sled The CPG2500 Calibration Sled Kit is available to provide a way to calibrate the barometric reference re- motely. Calibration of the Barometric Reference can be performed remotely using the Cal sled, a PC and the software provided.
We use this knowledge in our continuing effort to design better and more robust instruments. Spare Parts Table 9.2 lists the spare parts for the CPG2500 that can be ordered from Mensor. Table 9.2 - Spare Parts List Part Description...
The recommended calibration medium is dry nitrogen or clean dry instrument air. Hydraulic media can be used above 15 psi. A height variation between the standard and the CPG2500 can cause significant errors. A calculation should be made to compensate for this difference.
