Data Acquisition System (DAS) and APICOM 
Teledyne API – Model T300/T300M CO Analyzer

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.).
