5.2. Error Messages and Troubleshooting
STATUS: INVALID CALIBRATION
This message is only displayed when a calibration has been interrupted by pressing NO,
opening the sample door, or none of the electrodes are calibrated. Perform a calibration to
return to the H-READY Mode.
STD A NOT FOUND
This message is displayed when the sample sensor is unable to properly detect the STD A
solution in a programmed time period. As the analyzer draws a sample of STD A, the
leading edge of the solution is detected by the sample sensor. The sample sensor must
also detect a continuous flow of STD A Solution into the sample chamber, lasting several
seconds, without encountering air bubbles. After several seconds, the trailing edge of the
STD 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 STD A tubing or electrode chamber.
• Ensure that the sample sensor is plugged in securely and perform Check Sample
Sensor 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 Fluid Pack. If less than 5% remains, replace the
Fluid Pack.
• Prime system; look for fluid flow through system.
STD B NOT FOUND
STD C NOT FOUND
The system for drawing STD B or C is like that of STD A. If STD A is drawn properly
and STD B or C is not detected, check STD B tubing for crystallization. Perform checks
for STD A detection problems to correct. During the calibration sequence, STD B or C is
drawn into the measuring chamber prior to STD A, therefore check if STD A calibrant
can be properly detected to isolate possible fluidic faults. If neither STD A, B nor C are
detected check for air leaks or blockages within the fluidic path.
