RADIOMETER ABL800 FLEX User Manual

To activate the clot-detection feature
Contact a Radiometer representative and request that clot detection
be enabled via the service program.
Clot-detection process
During calibration the measuring chamber is rinsed and the pH of
the Rinse solution is measured. The value is stored in the analyzer.
During a sample measurement the measuring chamber is also rinsed
and the pH of the rinse solution is measured and compared with the
pH value stored during the last calibration. If the difference between
these values (the pH drift) exceeds a pre-determined maximum
value, it could indicate the presence of a clot beneath the pH
electrode.
When enabled, the clot-detection feature can generate three new
messages that are listed below.

NOTICE: Operator actions are listed in order of priority. Perform
the first action in the list and the actions indicated in the "Removal
condition(s) list. If the message persists, perform the next listed
action and the actions indicated in the "Removal condition(s) list,
and so on.
No. Message Interpretation Operator action(s)
Clot suspected
beneath pH
electrode*
The difference
between the pH of
the rinse solution,
measured during the
sample measurement,
and that stored after
the last calibration
exceeds the
maximum allowable
drift.
This indicates the
presence of a clot in
the measuring
chamber beneath the
pH electrode.
Remove the pH electrode and
check the measuring chamber for
clots: clean the measuring
chamber with a cotton stick
moistened with distilled water.
Make sure no cotton fibers are
left in the measuring chamber
Clean pH electrode
Remembrane Ref electrode
Replace pH electrode
Perform a 1- or 2-point calibration
Removal condition(s):
 Acknowledge execution of the
"Clot removal procedure"
 Successful 1- or 2-point
calibration
