■ Control card program
The TOC Control Software features an
integrated control card program. This way,
the user does not need to transfer values
manually. This is done automatically by the
system.

In the cards, control and warning limits are
defined that must not be exceeded. They can
be determined automatically by the program
(in a so-called pre-period) or manually
entered by the user.

With the software, the following control cards
can be generated and applied: ■ Recommended analyzer / Configuration
- TOC-V / L
 Mean value control cards - TOC-Control V / L
 Blind value control cards
 Recovery control cards
 Span width control cards
 Individual control cards
(target value control)
An editable cell also provides the option to
comment on the result entries.
