Barometric Sensor (optional) Removal To remove the optional Barometric reference sensor, first turn off the CPC7000 and loosen the Phillips head screws that secure the door. The barometric reference sensor is positioned behind the front door next to the primary transducer in the pressure controller (Figure 9.1.3).
15-45°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 CPC7000 operated within its temperature band, and with proper zero and span adjustments, will provide accurate pressure measurements.
