5.2 Error Messages and Troubleshooting
STATUS: NOT CALIBRATED
This message is only displayed when a calibration has been interrupted by
pressing NO or opening the sample door. Perform a calibration to return to the
READY Mode.
STANDARD A NOT DETECTED
This message is displayed when the sample sensor is unable to properly detect
the Standard A solution in a programmed time period. As the analyzer draws a
sample of Standard A, the leading edge of the solution is detected by the
sample sensor. The sample sensor must also detect a continuous flow of
Standard A Solution into the sample chamber, lasting several seconds, without
encountering air bubbles or air. After several seconds, the trailing edge of the
Standard A sample is sensed, the peristaltic pump stops and measurement
occurs.
Possible causes and remedies:
• Check for air leaks preventing the Standard from being drawn into the
chamber. Ensure that all O-rings are in place. There must be a
continuous draw of standard solution, free of air bubbles.
Check solenoid V for proper sealing of the vent line.
Check fill port to ensure the absence of air leaks.
• Check for clots or crystals formed in the Standard A tubing or
electrode chamber.
• Ensure that the sample sensor is plugged in securely and perform
Sample Sensor Test to ensure sensor is operating correctly. Clean,
adjust or replace sample sensor to correct sample sensor operation.
• Replace peristaltic pump tube set to ensure proper sample aspiration.
• Check the fluid remaining in the ISE SnapPak
TM
. If less than 5%
remains, replace the ISE SnapPak
TM
.
