ADVANCED FEATURES OF THE M400E
ANALYZER
7.1. USING USING THE DATA ACQUISITION SYSTEM (IDAS)
The M400E 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
M400E 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 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).

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.

analysis, documentation and archival in electronic format.
To support the iDAS functionality, Teledyne Instruments offers APICOM, a program that provides a visual
interface for remote or local setup, configuration and data retrieval of the iDAS (see Section 7.1). Using
APICOM, data can even be retrieved automatically to a remote computer for further processing. 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 document.

The M400E is configured with a basic iDAS configuration already enabled. The data channels included in this
basic structure may be used as is or temporarily disabled for later or occasional use.

Note
iDAS operation is suspended whenever its configuration is edited using the analyzer’s the 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-chip or CPU board is
replaced or if the configuration data stores there is reset.
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:

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.
