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.
