INSPECT FLUID PATH
After completion of sample measurement or calibration, the analyzer will monitor the
sample sensor to determine if the sample path has been cleared. This message will be
displayed if the sample path has not been cleared.
Possible causes and remedies:
• Check for blockages in the sample path, especially in the sample probe, the tubing to the
sample sensor and in the sample sensor.
• Check sample sensor is securely plugged in and check sample sensor under SERVICE MENU
to ensure correct operation.
• Check peristaltic pump and tubing are correct and all tubing is properly in place.

In case the analyzer displays arrows up or arrows down instead of sample results, the
concentration of the sample is outside of the measurement range.
Possible causes and remedies:
• If the sample is a urine sample, arrows up instead of the K+ result indicate that further dilution
of the specimen is required.
• Check for proper sample preparation.
• Ensure that the sample is correctly aspirated into the measuring chamber and ensure small air
bubbles are not present.
• Check for proper aspiration of STD A.
