Calibration Procedures

Model GFC7000TA Carbon Dioxide Analyzer

7.5. Manual Calibration Checks with Zero/Span Valves

Zero and span checks using the VARIOUS zero/span valve options available for the GFC 7000TA are similar to that described in Section 7.3, except that the zero and calibration operations are initiated directly and independently with dedicated buttons CALZ and CALS.

To perform a manual calibration check of an analyzer with a valve option installed, use the following method.

STEP ONE: Connect the sources of Zero Air and Span Gas as shown in Figures 7-3 through 7-6.

STEP TWO: Perform the zero/span check.
