Cause Solution
The instrument does not
receive any buffer or
indicator solution.
Remove the two reagent lines from the Y connector. Only one drop
of reagent comes out per cycle. If no reagent comes out, examine
the pressure plate. Make sure that the pinch block is not
overtightened and the reagent lines are not pinched. Examine the
back of the pinch block for grooves. Replace the pinch block if
necessary.
The chemistry does not
operate correctly.
Mix 1-mL of each reagent and 80-mL of sample. A color change
must show. If no color change shows, replace the reagents.
The instrument does not
operate correctly.
Pinch the sample inlet line to stop the sample flow. The next cycle
reads soft. If it does not read soft, examine the LED if it shows an
orange light. Examine the photocell and clean if necessary. After this
cycle, the instrument reads hard again.
