3.6.3. Pneumatic Connections in Multipoint Calibration Applications

Some applications may require multipoint calibration checks where span gas of several different concentrations is needed. We recommend using high-concentration, certified, calibration gas supplied to the analyzer through a Gas Dilution Calibrator such as a Teledyne Instruments Model T700. This type of calibrator precisely mixes Span Gas and Zero Air to produce any concentration level between 0 ppm and the concentration of the calibrated gas.

Figure 3-12 depicts the pneumatic set up in this sort of application of a Model GFC 7000TA CO2 Analyzer with ambient zero/ambient span valve option 50A installed (a common configuration for this type of application).

3.6.4. Setting the Internal Purge Air Pressure

In order to maintain proper purge air flow though the GFC wheel housing, a manually adjustable pressure regulator is provided (see Figure 3-5). This regulator includes two output ports. One is used to supply purge air to the GFC wheel. The other may be used to attach a pressure gauge.

To adjust the internal purge air pressure of the GFC 7000TA:

1.Turn off the instrument.

2.Remove the source of zero air attached to the purge line inlet port at the back of the analyzer.

3.Remove the analyzer’s top cover.

4.Remove the cap from the second, unused, output port on the pressure regulator.

5.Attach a pressure gauge capable of measuring in the 5-10 psig range with 0.5 psig resolution to the port.
