Troubleshooting
The XDS MasterLab Analyzer is a dependable, trouble-free instrument, designed for many years of
service in your laboratory. In spite of the rugged design, problems may arise that require attention.
This guide is intended as a means of diagnosing minor problems.
There are no user-serviceable parts inside the instrument enclosure.
Because of this design, we emphasize that under no circumstances should the user attempt to open
the instrument cabinet and service any part. The components are may be damaged or misaligned by
handling. Hazardous voltages may be present even with power removed from the system.
Any diagnosis of internal function should be performed using software diagnostics, not by
internal inspection.
For minor problems, this guide should be consulted. While some recommendations are quite basic,
some of the suggestions may be helpful in avoiding oversights or problems. Follow the
recommendations and eliminate any possible causes listed. Recommendations are listed in logical
order of occurrence wherever possible
When all recommendations have been checked, and if the instrument is not operating, please contact
Metrohm Service or your local authorized distributor if the problem is not solved.
