Photometric Analyzer Operation 3
Part I 3-23 Teledyne Analytical Instruments
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.
Enter the Range function to start the Range function.
