With the zero/span assembly option, a source of span gas is connected to
the SPAN port and a source of zero air is connected to the ZERO port as
shown in Figure 9–1. Zero and span gas should be supplied at atmospheric
pressure. It may be necessary to use an atmospheric dump bypass plumbing
arrangement to accomplish this.
