•Ranges whose limits are entirely within the span of an adjoining range.

•Ranges where the zero is suppressed, is 1-10, 1-100, etc, however, 80-100, 90-100 is ok where the zero gas is actually 100% concentration and the calibration is inverted.

•In Oil and Water applications, because the range and cell path are pertinent to the water background and preparation of zero fluid by the sample system, the autorange feature should not be used. Only single range is recommended.

Figure 3-2 illustrates these schemes graphically.
