Foss NIRS DS3, User Manual

Page: 79 / 86

The NIRS DS3 / DS3 F analyser is designed to be a dependable, trouble-free
instrument with many years of use. In spite of the rugged design, problems may
arise that require attention.
There are no user-serviceable parts inside the instrument enclosure except the
lamp. Because of this design, we emphasise that under no circumstances should the
user attempt to open the instrument cabinet and service any part other then the
lamp. Trying to do so may damage or misalign components. Any diagnosis of
internal functions should be performed using software diagnostics, not by internal
inspection. In the event internal components should need replacement or other
service such actions must be done by a trained service engineer.
System failure can be detected by malfunctions and error messages. Follow the
recommendations and eliminate any possible causes listed.
If the instrument is still not operating, after all the recommendations have been
checked, please contact your local FOSS service centre or your local authorised
distributor.
To get a fast and accurate response when reporting a malfunction, it is essential
that you provide relevant information in as specific detail as possible. Before
calling for help, please answer the following questions:
•
Can I already pinpoint the root cause of the problem myself?
•
When did I first see the problem?
•
Can I repeat the problem with a certain action, sequence or other method?
•
Is the problem consistent or does it occur intermittently?
•
Has it escalated in frequency or severity?
•
Is the problem seen at specific times?
Environmental conditions shall also be considered, e.g. vibrations, electricity,
temperature, humidity, etc.
If the problem is related to unsatisfactory results the following questions are also
relevant.
•
Does it happen on all products or just one or some products?
•
Is the instrument performing according to the application specification or not?
•
Are the problematic samples 'normal' or extraordinary in any obvious way?
•
Is the problem repeatable if I rerun the sample or repack the sample cup?
The Instrument Diagnostics test will prove your instrument performance from day
to day. Results and data from this test can often suggest the origin of a problem.
