1.8.3 Internal zero/span

The IZS option includes the valves and connection parts described above, and in addition, includes an internal zero air scrubber. This scrubber operates by catalyticly converting CO in the gas stream to CO2. If the Analyzer is equipped with the IZS option, Span gas connections should be made as described above and a source of clean air at ambient pressure should be connected to the IZS/Zero Air Port on the Analyzer's rear panel.
