5.7.2. INTERNAL ZERO/SPAN GAS GENERATOR (OPTION 51A)
The M100E can be equipped with an internal zero air and span gas generator (IZS). This option includes a
heated enclosure for a permeation tube, an external scrubber for producing zero air and a set of valves for
switching between the sample gas inlet and the output of the zero/span subsystem, functionally very similar to
the valves included in the zero/span valve option.
Figure 5-4 shows the internal pneumati
c
connections for a M100E with the IZS option installed. Table 5-5
describes the operational state of the valves associated with the IZS option during the analyzer’s various
operating modes.
