In dual or auto range modes, “HIGH” or “LOW” is displayed to indicate
the calibration of the high or low coefficient. The following example shows
the coefficient screen in dual/auto range mode.
Note
The screen will show “SPAN CONC NOT VALID” if the
coefficient change causes the concentration to be either higher than the
selected range or less than or equal to zero.

The Calibration menu is used to automatically set the zero background and
the span coefficient. The calibration menu is similar for the single, dual,
and autorange mode as shown below. The dual and autorange modes have
two HCl span factors (high and low). This allows each range to be
calibrated separately. This is necessary if the two ranges used are not close
to one another. For example, a low HCl range of 0-5 ppm and a high HCl
range of 0-5000 ppm. For more information about calibration, see Chapter
4, “
