The T101 analyzer contains a flexible and powerful, internal data acquisition system
(DAS ) that enables the analyzer to store concentration and calibration data as well as a
host of diagnostic parameters. The DAS of the T101 can store several months of data,
depending on how it is configured. The data are stored in non-volatile memory and are
retained even when the instrument is powered off. Data are stored in plain text format for
easy retrieval and use in common data analysis programs (such as spreadsheet-type
programs).
The DAS is designed to be flexible. Users have full control over the type, length and
reporting time of the data. The DAS permits users to access stored data through the
instrument's front panel or its communication ports. Using APICOM, data can even be
retrieved automatically to a remote computer for further processing.
The principal use of the DAS is logging data for trend analysis and predictive diagnostics,
which can assist in identifying possible problems before they affect the functionality of
the analyzer. The secondary use is for data analysis, documentation and archival in
electronic format.
To support the DAS functionality, Teledyne ML offers APICOM, a program that
provides a visual interface for remote or local setup, configuration and data retrieval of
