8 Troubleshooting

This chapter helps to resume operation after a minor problem has occurred with the instrument. It lists

possible occurrences, their probable cause and suggests how to remedy the problem.

is enabled to correct some of those problems or errors by him/herself. For this, appropriate corrective

measures are listed in the column “Corrective measure”.

The elimination of more complicated malfunctions or errors is usually performed by a BUCHI technical

engineer who has access to the ofﬁcial service manuals. In this case, please refer to your local BUCHI
