The Initial Sample/Reference (S/R) Ratio screen displays both the initial
S/R ratio and the current S/R ratio. The initial S/R ratio is determined at
the factory, and is used to correct for the slight variations found from one
correlation wheel to another. The only time the initial S/R ratio should be
changed is when the correlation wheel is replaced or sample/reference is
between 1.05 and 1.15. The initial sample/reference ratio screen is visible
only when the instrument is in service mode. For more information on the
service mode, see “
Service Mode
” earlier in this chapter.
Note
This adjustment should only be performed by an instrument service
technician.
