Troubleshooting
The XDS MultiVial 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 Department (or your local authorized
distributor) if the problem is not solved.
