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.

3.6.1 Manual (Select/Define Range) Screen

The Manual range-switching mode allows you to select a single, fixed

analysis range. It then allows you to redefine the upper and lower limits, for the

range.
