different gas. In this way the conversion factor for each gas is
stored in separate filter banks (for stand-alone use see
).
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?
