  • Page 56 Vacuum Calibrator CPG2500 10 Calibration 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.
