DATA ACQUISITION SYSTEM (DAS) AND APICOM
The T200 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 feature of the T200 can store a large number of
data points, which can, depending on individual configurations, cover days, weeks or
months of valuable measurements. The data records 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 electronic
spreadsheets).
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 remotely through its communication ports.
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 API offers APICOM, a program that
provides a visual interface for remote or local setup, configuration and data retrieval of
the DAS. Using APICOM, data can even be retrieved automatically to a remote
computer for further processing. The APICOM manual, included with the program,
contains a more detailed description of the DAS structure and configuration and is
briefly described in this document.
The T200 is configured with a basic DAS configuration already enabled. The data
channels included in this basic structure may be used as is or temporarily disabled for
later or occasional use.
The green SAMPLE LED on the instrument front panel, which indicates the analyzer
status, also indicates certain aspects of the DAS status:
Table 7-1: Front Panel LED Status Indicators for DAS
LED STATE DAS Status
OFF
System is in calibration mode. Data logging can be enabled or disabled for this mode. Calibration
data are typically stored at the end of calibration periods, concentration data are typically not
sampled, diagnostic data should be collected.
BLINKING
Instrument is in hold-off mode, a short period after the system exits calibrations. DAS channels can
be enabled or disabled for this period. Concentration data are typically disabled whereas diagnostic
should be collected.
ON Sampling normally.
