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.
