3.6 The Range Select Function
The Range function allows you to manually select the concentration range
of analysis (MANUAL), or to select automatic range switching (AUTO).
In the MANUAL screen, you are further allowed to define the high and low
(concentration) limits of each Range, and select a single, fixed range to run.
CAUTION: If this is a linearized application, the new range must
be within the limits previously programmed using the
System function, if linearization is to apply through-
out the range. Furthermore, if the limits are too small
a part (approx 10 % or less) of the originally linear-
ized range, the linearization will be compromised.
