Troubleshooting the Analyzer 5-51
Perox Chamber
PEROX 3 reagent is used up before PEROX 2 reagent bottle is empty.
Perox reaction chamber overflows
•
Check for blockage in the perox reaction chamber cap. Clear any blockage
using a drill bit or a paper clip.
•
Check for blockage or crimps in the perox overflow tube.
•
Make sure that the ends of the tubes do not touch the bottom of the overflow
bottle nor are they submerged in liquid.
NOTE
If the opening on overflow-bottle cap is not large enough and pinches the tubes,
cut the rubber cap from the outside edge to the inner opening to relieve some of
the pressure on the tubes.
