The internal span gas generator utilizes an NO
the section on "Internal Span Gas Generation" that follows). The accuracy of these devices
is only about ±5%. Whereas this may be sufficient for frequent automated calibration
checks (Figure 2-22), we recommend using certified NO gases for precise calibration
(Figure 2-23).
