    This section is included for those who wish to calibrate their CPC8000 within their own calibration lab. Because calibration involves special training and calibration components that are not addressed here, only personnel qualified in calibration procedures should be allowed to calibrate the CPC8000.

  • Page 68: Calibration Adjustment Procedure

    7.5.2.5 Calibration Adjustment Procedure There are three methods that can be used to calibrate all of the transducers in the CPC8000. A simple [1-Point Calibration] can be used to adjust a single point (usually the zero point). A [2-Point Calibration] extends this capability to adjust two points (usually points close to the Zero and Span).

  • Page 69: 1-Point Calibration

    With an absolute transducer, the instrument should be put in [Measure] mode with an appropriate high accuracy reference standard connected to the Measure/Control port on the back of the CPC8000 . If a sub-atmospheric zero point is required, a vacuum pump can be connected to the Measure/Control port to bring the pressure down to a value closer to absolute zero .

  • Page 70: 2-Point Calibration

    After the value has been accepted by pressing the [check] mark on the numeric key pad the value will appear with a green background where the [New Value] button was. These actions complete the low point calibration . Operating Instructions - CPC8000...

  • Page 71: Linearize

    The [Linearize] application (see figure 7.5.2.5.3a) provides a place to record [As Found] calibration data and to linearize each internal transducer in the CPC8000 using that data . An “as found calibration” can be performed by connecting a suitable pressure standard to the Measure/Control port, placing the instru- ment in [Measure] mode and supplying all 11 pressure points across the complete range of the trans- ducer being calibrated.

  • Page 103: Model 75 Pressure Booster System

    9.4 Model 75 Pressure Booster System To control pressure, the CPC8000 requires a pressure supply of 10% above the full scale of the instru- ment. For ranges of 3000 psi or greater, this is above the typical gas bottle/cylinder. The Model 75 Pressure Booster System provides the ability to boost bottle pressure up to the supply pressure require- ments of all possible CPC8000 range configurations while maximizing gas bottle/cylinder usage.
