4.7. SETUP DAS - USING THE DATA ACQUISITION SYSTEM
(DAS)
The T200H/M 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 data points can cover days, weeks or
months of valuable measurements, depending on how the DAS 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).
Note Please be aware that all stored data will be erased if the analyzer’s disk-
on-module, CPU board or configuration is replaced/reset.
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. Teledyne API also offers
APICOM, a program that provides a visual interface for configuration and data retrieval
of the DAS or using a remote computer. Additionally, the analyzer’s four analog output
channels can be programmed to carry data related to any of the available DAS
parameters.
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.
DAS STATUS
The green SAMPLE LED on the instrument front panel, which indicates the analyzer
status, also indicates certain aspects of the DAS status:

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.
The DAS can be disabled only by disabling or deleting its individual data channels.
