The Auto TOC Mode
In this normal (default) operating mode, the Anatel A643a conducts analysis and reporting
functions based on its particular parameters. Water samples are analyzed independently by
each instrument, their corresponding results displayed on the associated C80 Controller at the
conclusion of each analysis cycle. Printouts are generated by an Analyzer’s attached printer as
specified on its
Printer Setup Menu . Automatic analysis and reporting continues until manually
interrupted by the user or until a critical fault is encountered.
To select the Auto TOC Mode:
1) With the desired Analyzer selected in any View, press Manual to display its operational
options.
2) Use the Up and Down Keys to specify Auto TOC.
3) Press Enter to enable the Auto TOC Mode.
In this mode, water analyses are conducted automatically by the Anatel A643a using a
patented procedure. TOC measurement uses a microprocessorcontrolled photocatalytic
process in conjunction with conductivity detection. The initial conductivity of the water sample
is determined to establish a reference value. An ultraviolet lamp then oxidizes the sample and
