7.1.SETUP  IDAS: USING THE DATA ACQUISITION SYSTEM (IDAS)

The M300E/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 M300E/EM can store up to about one million data points, which can, depending on individual configurations, cover days, weeks or months of valuable measurements. The data is stored in non-volatile memory and is retained even when the instrument is powered off. Data is stored in plain text format for easy retrieval and use in common data analysis programs (such as spreadsheet-type programs).

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.

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.

To support the iDAS functionality, Teledyne API offers APICOM, a program that provides a visual interface for remote or local setup, configuration and data retrieval of the iDAS. The APICOM manual, which is included with the program, contains a more detailed description of the iDAS structure and configuration, which is briefly described in this manual.

The M300E/EM is configured with a basic iDAS configuration, which is enabled by default. New data channels are also enabled by default at their creation, but all channels may be turned off for later or occasional use.

Note

iDAS operation is suspended whenever its configuration is edited using the analyzer’s front panel and therefore data may be lost. To prevent such data loss, it is recommended to use the APICOM graphical user interface for iDAS changes.

Please be aware that all stored data will be erased if the analyzer’s Disk-on-Module or CPU board is

replaced or if the configuration data stored there is reset.

Since all changes to the configuration of the iDAS cause all of the existing data to be erased, it is

recommended to download your stored data prior to making any changes.

7.1.1.IDAS STATUS

The green SAMPLE LED on the instrument front panel, which indicates the analyzer status, also indicates certain aspects of the iDAS status:

	Table 7-1: Front Panel LED Status Indicators for iDAS
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, as opposed to suspended, only by disabling or deleting its individual data channels.
