Note: The command lines 1 to 6 are only necessary, if dosing drives
are connected to the Sample Processor for adding auxiliary solutions.
In the 797 VA Computrace software the parameter "Dose auxiliary so-
lution via sample processor" in the configuration dialog "Settings /
General settings / Automation" must be activated.
If adding of auxiliary solutions is operated by the 797 VA Com-
putrace, line 1 to 6 have to be deleted.
