6.7. SETUP DAS - USING THE DATA ACQUISITION SYSTEM
(iDAS)
The M200EH/EM analyzer contains a flexible and powerful, internal data acquisition system (iDAS) that enables
the analyzer to store concentration and calibration data as well as a host of diagnostic parameters. The iDAS of
the M200EH/EM can store up to about one million data points, which can, cover days, weeks or months of
valuable measurements. 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-chip, CPU
board or configuration is replaced/reset.
The iDAS is designed to be flexible. Users have full control over the type, length and reporting time of the data.
The iDAS permits users to access stored data through the instrument’s front panel or its communication ports.
Teledyne Instruments also offers APICOM, a program that provides a visual interface for configuration and data
retrieval of the iDAS 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 iDAS parameters.
The principal use of the iDAS 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.
IDAS STATUS
The green SAMPLE LED on the instrument front panel, which indicates the analyzer status, also indicates
certain aspects of the iDAS status:

LED STATE IDAS 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. IDAS
channels can be enabled or disabled for this period. Concentration data are typically
disabled whereas diagnostic should be collected.
On Sampling normally.
The iDAS can be disabled only by disabling or deleting its individual data channels.
