DAC and APICONTeledyne API – Model T300/T300M CO Analyzer

Teledyne Analytical Instruments 164

Note DAS 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 DAS changes (Sections .

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.

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

channels.

7.1. DAS STRUCTURE

The DAS is designed around the feature of a “record”. A record is a single data point.

The type of data recorded in a record is defined by two properties:

PARAMETER type that defines the kind of data to be stored (e.g. the average of gas

concentrations measured with three digits of precision). See Section 7.1.6.

A TRIGGER event that defines when the record is made (e.g. timer; every time a

calibration is performed, etc.). See Section 7.1.5.

The specific PARAMETERS and TRIGGER events that describe an individual record

are defined in a construct called a DATA CHANNEL (see Section 7.1.1). Each data

channel is related one or more parameters with a specific trigger event and various other

operational characteristics related to the records being made (e.g. the channels name,

number or records to be made, time period between records, whether or not the record is

exported via the analyzer’s RS-232 port, etc.).

7.1.1. DAS DATA CHANNELS

The key to the flexibility of the DAS is its ability to store a large number of

combinations of triggering events and data parameters in the form of data channels.

Users may create up to 50 data channels and each channel can contain one or more

parameters. For each channel, the following are selected:

 One triggering event is selected.

 Up to 50 data parameters, which can be the shared between channels.

 Several other properties that define the structure of the channel and allow the user to

make operational decisions regarding the channel.
