Applications
The CPG2500 Vacuum Calibrator is a precision vacuum indicator and calibrator designed to test and calibrate absolute pressure transducers and indicators. The CPG2500 has a precision vacuum transducer capable of measuring vacuum pressure with 1 mTorr accuracy.
The CPG2500 automatically adjusts the pressure reading for the effects of temperature and non-linearity within the calibrated temperature range of 15-40°C. The process is referred to as dynamic compensation because each reading is so adjusted before it is output to the display or to a communication bus. Thus, a calibrated CPG2500 operated within its temperature band, and with proper zero and span adjustments, will provide accurate pressure measurements. The CPG2500 should have the calibration verified periodically to ensure stability. The recommended calibration cycle is one year.
Overview
Configuration of the CPG2500 is achieved by changing settings accessed through the Application (“App”) buttons. Local operation is accomplished by observing the data presented in the display. The appearance and functionality of the display can be changed by pressing the App button for the related function. After an app has been chosen, a set of related parameters will appear on the left. After choosing one of these parameters, a set of selections related to that parameter will appear on the right or a data entry keypad. The desired selection or data can be entered here.
The measure port for the vacuum calibrator is located at the rear panel of the CPG2500. Positioned on the left side are the remote transducer connection, the RS-232, Ethernet, IEEE-488, USB device connections for communication, the USB host connection, and the 12 VDC power input.
