WHEN CHECK DESCRIPTION SOLUTION
1) Unplug the pump tubing’s from their
respective pumps and check if they are
marked, thinner, and/or lost their original
shape. Compare the tubing’s length with a
new set (it is recommended to always
keep a new set in stock, since an
accidental brake can occur at any time.
In that case the liquid is spread on the
instrument and electric interference is
possible, as well as (in the worst case),
permanent corruption of the system.
2) Observe if, during measurement the
liquid inside the coils behind the chamber,
stops when the pumps stop, or flows
continuously. If the flow continues during
the measure time, the tubing’s are not in
proper sealing conditions.
ONCE / month
Consumption of
peristaltic pump tubing’s
(SPP312-316)
3) Observe if during the wash cycle (
Clean
or F3 ) the liquid comes up to the top of the
mixing chamber. If not, tubing’s are not in
proper sealing conditions.
Replace all pump tubing’s with
a new set, not only the
damaged ones.
Every day Check the efficiency of
level pump
(pump 3). At the end of each cycle, pump 3 aspirates
liquid from the top of the mixing chamber,
in the tube, the last two centimetres are
only air (or bubbles). If not, report to
technical assistance. Report the problem to technical
assistance
During working
session Place the reaction graph
properly inside the
maximum and minimum
limits. The D1 (first few seconds of the reaction)
must be a flat line and must overlap to the
following reaction one (Figure 1). If the line
is not flat (Figure 2), there is a possible
contamination in the reference electrode,
called Enzyme Contamination;
see § 5.4
If the line is flat but does not overlap to the
next cycle one, there is possibly a cloth in
the fluidics or enzyme contamination in the
reference electrode see § 5 Figure1-2
see § 6.2.3
