If the malfunction is severe enough to make the measurement result unreliable,
the refractometer cannot be used in making the divert decision. In that case the
instrument is dropped from the Divert Control System, and cannot be taken on-line
manually until the problem is 󰅮ixed.
For more information on possible causes of each error, see the PR-23 instruction man-
ual, Chapter 8.
