Calibration Procedures

Model GFC7000TA Carbon Dioxide Analyzer

7.1.2. Calibration Gas Traceability

All equipment used to produce calibration gases should be verified against standards of the National Institute for Standards and Technology (NIST). To ensure NIST traceability, we recommend acquiring cylinders of working gas that are certified to be traceable to NIST Standard Reference Materials (SRM). These are available from a variety of commercial sources.

7.1.3. Data Recording Devices

A strip chart recorder, data acquisition system or digital data acquisition system should be used to record data from the GFC 7000TA’s serial or analog outputs. If analog readings are used, the response of the recording system should be checked against a NIST traceable voltage source or meter. Data recording device should be capable of bi-polar operation so that negative readings can be recorded. For electronic data recording, the GFC 7000TA provides an internal data acquisition system (DAS), which is described in detail in Section 6.7.

7.2. Manual Calibration without Zero/Span Valves

This is the basic method for manually calibrating the Model GFC 7000TA CO2 Analyzer without functioning zero/span valve options. It is identical to the method described in the GETTING STARTED (Section 3) of this manual and is repeated her for you convenience.

STEP ONE: Connect the Sources of Zero Air and Span Gas as shown below.
