Factor Used for sample and control results.
Final result = (result * Factor) + Offset
The correlation factor is used to compensate for
differences in measuring methods of different
analyzers. By applying a factor, the final results
of the different analyzers can be directly com-
pared.
Offset The offset is used to compensate for differences
in measuring methods of different analyzers. By
adding the offset, the final results of the different
analyzers can be directly compared.
Used On, Off Choose On to ensure that the defined factor and
offset are applied the final ratio result.
