    Figure 3-1: Front Access Door 3.3 Rear Panel Connections Figure 3-2 shows the Model 3000RS-T rear panel. There are ports for gas, power, and equipment interface. The Zero in and Span in ports are not included on the standard model but are available as options.

  • Page 34: Gas Connections

    The gas ports are 1/8”. The analyzer does not have flow control, therefore a needle valve or an orifice/restrictor is going to be needed to control the flow into the analyzer. If the 3000RS-T has three inlet ports, for zero, sample, and span, then each port will need its own flow control device.

    5.2.1 Storing and Handling Replacement Cells To have a replacement cell available when it is needed, it is recom- mended that one spare cell be purchased 9-10 months after commissioning the 3000RS-T, or shortly before the end of the cell's one year warranty period. CAUTION: DO NOT STOCKPILE CELLS.
