different gas. In this way the conversion factor for each gas is

stored in separate filter banks (for stand-alone use see

Fig.12.8

).

The gas conversion factor stored in the selected filter bank during

a span calibration task will be overwritten by the new gas

conversion factor calculated during the span calibration of the

filter.

Gas to be Used During Span Calibration

The gas you need to use during span calibration must be the gas you

wish to measure with the filter.

Type of Span Calibration – Single-point or Two-point?

calibration task
