10.1.1 Overview of maintenance work for the analyzer
The following service instructions refer to the usual steel analyses using the analyzer with 10 to
30 samples per day and 99.5 % pure oxygen. Depending on the application, the maintenance
cycle may need to be intensified to maintain the precision of analysis results.
The following table lists the maintenance work to be carried out. The maintenance work must
