RETRYING WASH The prism wash failed the wash check (Section 5.9.4). The
(Sanitary refractometer PR-03-A prism wash will be attempted as many times as is set by the
and probe refractometer PR-03-P) Wash retry parameter (Section 5.9.4).
WASH STOP/TEMP LIMIT The process temperature is below the temperature limit set for
(Sanitary refractometer PR-03-A wash stop (Section 5.9.3). The message is shown until wash
and Probe refractometer PR-03-P) succeeds or the RESET key is pushed.
LOW CONCENTRATION/NO SAMPLE Normally caused by empty process pipe or exceptionally low
concentration.
If pipe is full and sample indicates normal concentration,
check the optical image (Section 7.2).
HIGH PROCESS TEMPERATURE Process temperature is above the set limit (Section 5.7). Com-
mon causes are abnormal process conditions or a leaking
prism wash steam valve.
LOW LIGHT INTENSITY Most common cause is onset of prism coating.
DIP IN IMAGE Indicates irregular optical image. Can be caused by a speck of
dust on the CCD window.
HIGH CONC/PRISM COATED Is most commonly caused by prism coating, but may also indi-
cate exceptionally high concentration. If sample is normal and
the message persists after the prism surface is cleaned, check
the optical image (Section 7.2).
** WASH STOP/EXT. STOP ** Caused by closing an input switch that has been activated for
