Troubleshooting
Most operational problems are caused by the following:
• Leaks (commonly around the sample tube O-ring at the analysis port)
• Sample weighing errors

• Entry of incorrect system volume for analysisï€
Always check these first when expected analysis results are not obtained. Some common operational
problems, which are not indicated on the computer screen, and their respective causes and solutions
are provided in the following table.
