Figure 2-5 Piping Layout

Figure 2-5 is the Piping Layout of the sampling system. In the

standard instrument, calibration gases (zero and span) are con-

nected directly to the Span Gas In port by teeing to the port with

appropriate valves. The sample gas is connected to the Sample

Gas In port in the same manner as the Span Gas.
