Error messages/symptoms Sources of error Troubleshooting
- A clattering sound can be heard. - The visible clamping screws
have become loose during sec-
tioning.
These symptoms may occur
from time to time and are un-
avoidable, as the clamping
screws which have to be op-
erated by the user cannot be
sealed.
- Retighten the loose clamping
screws.
If the clattering sound does
not cease once the clamping
screws have been retight-
ened, do not hesitate to call
the Technical Service imme-
diately.
Do not use the instrument
when in this condition.
