Setting Up Xtal SL DPM % of Reference
When editing a User Program, from the Data Calculation Menu (Figure 5.1), choose XTAL SL
DPM%Ref. The prompts displayed on the menu are the same as described for the Xtal DPM

Loading Samples for Xtal SL DPM% of Reference
Since the instrument has no way of distinguishing among blanks, standards, references, and
unknowns, a convention has been established for identifying them by the sequence in which
they are loaded. An example loading sequence is shown in Figure 5.16.
