Teledyne t320u Manuale Utente

Teledyne API – Model T300/T300M CO Analyzer 

Data Acquisition System (DAS) and APICOM 

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. 

NAME 

The name of the data channel. 

Up to 6 letters or digits 

1.  

TRIGGERING 

EVENT 

The event that triggers the data channel to measure 
and store the datum. 

Any available event  

(see Appendix A-5). 

NUMBER AND 

LIST OF 

PARAMETERS 

A User-configurable list of data types to be 
recorded in any given channel. 

(COMEAS) 

Any available parameter 

(see Appendix A-5). 

REPORT PERIOD 

The amount of time between each channel data 
point. 

000:00:01 to 

366:23:59 

(Days:Hours:Minutes) 

NUMBER OF 

RECORDS 

The number of reports that will be stored in the data 
file.  Once the limit is exceeded, the oldest data is 
over-written. 

1 to 1 million, limited by 

available storage space. 

RS-232 REPORT 

Enables the analyzer to automatically report 
channel values to the RS-232 ports. 

OFF or ON 

CHANNEL 

ENABLED 

Enables or disables the channel.  Allows a channel 
to be temporarily turned off without deleting it. 

OFF or ON 

CAL HOLD OFF 

Disables sampling of data parameters while 
instrument is in calibration mode

 More with APICOM, but only the first six are displayed on the front panel.

 When enabled records are not recorded until the DAS HOLD OFF period is passed after calibration mode.  DAS HOLD OFF SET in 

the VARS menu (see Section 7.1.11

. 

7.1.2. DEFAULT DAS CHANNELS 

A set of default Data Channels has been included in the analyzer’s software for logging 
CO concentration and certain predictive diagnostic data.  These default channels include 
but are not limited to: 

  CONC: Samples CO concentration at one minute intervals and stores an average 

every hour with a time and date stamp.  Readings during calibration and calibration 
hold off are not included in the data.   

  By default, the last 800 hourly averages are stored. 

  PNUMTC: Collects sample flow and sample pressure data at five-minute intervals 

and stores an average once a day with a time and date stamp.  This data is useful 
for monitoring the condition of the pump and critical flow orifice (sample flow) and 
the sample filter (clogging indicated by a drop in sample pressure) over time to 
predict when maintenance will be required.   

  The last 360 daily averages (about 1 year) are stored.
