Check Sample
Sensor
The sample sensor is calibrated
automatically with air during each
calibration. For proper functioning,
the sensor must provide a reading of
95 to 105 units for air.
•
Initiate
Check Sample Sensor
to verify air
reading.
•
Open the sample door and press
LOAD
SAMPLE
button to aspirate various Fluids
through the sensor. For transparent Fluids, the
reading should increase by at least 40 units. For
blood samples (not transparent), the reading
should decrease by at least 40 units. The pump
can be stopped by pressing
STOP.
•
Check for correct drying of the measuring
chamber during the wash cycle at completion of
test. If not drying, replace the peristaltic pump
tube set.
•
If response is not as expected, clean sample
sensor by performing
Daily Maintenance
. If
response is still not as expected, replace
Sample Sensor (
AV-BP5036D
).
•
Perform a calibration to remove the error
message.
Check Reference
Electrode
The reference electrode is
pressurized during STD-A aspiration
while the R valve is closed. When the
pressure is relieved, the sample
sensor will detect a back flow of STD-
A. If the sample sensor does not
detect a backflow of STD-A, this error
obtained.
When the analyzer fails to detect a
flow of Reference Solution into the
measuring chamber, this message
will be displayed. This test is
performed at the beginning of each
calibration cycle.
•
Look for ref segments coming out
•
Check for leaks around connectors, tubing and
electrode.
•
Ensure that the reference tubing is securely
connected to the receptacle.
•
Check that reference electrode is firmly installed
in the housing.
•
Check for the presence of o-rings and for proper
sealing of the electrodes
•
Under
DIAGNOSTICS/CHECK ELECTRODES,
initiate a reference check. Visually check and
confirm reference fluid has back flow in this test.
•
Examine for proper filling of the reference
housing.
•
Since this test utilizes Standard A, make sure
that it is aspirated properly into the measuring
chamber. If not, replace the Fluid Pack.
•
If the test fails, clean the reference housing.
(See chapter 5.4: "Monthly maintenance" in
Operators Manual.)
Clog Pathway
If the unit is unable to clear the
sample path or to aspirate any of the
3 Standards at the beginning of a
calibration.
the cause:
defective reference housing
(increased discharge of KCL)
leaks in Fluid path
defective pump tubing
defective sample sensor
pathway obstruction
•
Make sure that the electrode O- rings are
present and the seated properly.
•
Make sure electrodes are installed correctly in
electrode tray.
•
Check for clog or crystallization in the Fluid
path: especially in the sample probe, the tubing
to the sample sensor and in the sample sensor.
•
Ensure that the sample sensor is securely
plugged in and perform a sample sensor test to
ensure the sensor is operating correctly. If
necessary, clean the sample sensor.
•
Replace the reference electrode housing.
