STANDARD B NOT DETECTED
STANDARD C NOT DETECTED (9180/9181 only)
The system for drawing Standard B or C is like that of Standard A. If Standard A
is drawn properly and Standard B or C is not detected, check Standard B tubing
for crystallization. Perform checks for Standard A detection problems to correct.
During the calibration sequence, Standard B or C is drawn into the measuring
chamber prior to Standard A, therefore check if Standard A calibrant can be
properly detected to isolate possible fluidic faults. If neither Standard A, B nor C
are detected check for air leaks or blockages within the fluidic path.
CHECK SAMPLE SENSOR
The sample sensor must provide a reading of 80 - 120 when air is detected.
Perform Test Sample Sensor to observe sample sensor response. When clear fluid
(e.g. water) is aspirated, the sample sensor display must indicate an increase of of at
least 40 units. For blood samples (not transparent), the reading should decrease by
at least 40 units. The sample sensor is calibrated with air during each calibration.
Perform a calibration to remove the error message after troubleshooting.
Possible causes and remedies:
• Clean sample sensor using Daily Cleaning procedure.
• Check for correct drying of measuring chamber during the wash cycle.
• Replace peristaltic pump tube set.
• Test and adjust sample sensor to correct adjustment.
• Replace sample sensor assembly.
