Teledyne API - T100 UV Fluorescence SO2 Analyzer Data Acquisition System (DAS) and APICOM
155
Table 7-2: DAS Data Channel Properties
Property Description Default Setting Range
NAME
The name of the data channel. “NONE” Up to 6 letters and digits
(more with APICOM, but only
the first six are displayed on
the front panel).
TRIGGERING
EVENT
The event that triggers the data channel to measure
and store its data parameters. Refer to APPENDIX
A-5 for a list of available triggering events.
ATIMER Any allowed event.
NUMBER AND
LIST OF
PARAMETERS
A User-configurable list of data types to be
recorded in any given channel. Refer to APPENDIX
A-5 for a list of available parameters
1 - PMTDET Any available concentration,
temperature, pneumatic or
diagnostic parameter.
REPORT PERIOD
The amount of time between each channel data
point.
000:01:00 000:00:01 to
366:23:59
(Days:Hours:Minutes)
NUMBER OF
RECORDS
The number of reports that will be stored in the data
file. Once the specified limit has been exceeded,
the oldest data are over-written to make space for
new data.
100 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 OFF or ON
CHANNEL
ENABLED
Enables or disables the channel. Provides a
convenient means to temporarily disable a data
channel.
ON OFF or ON
CAL HOLD OFF
Disables sampling of data parameters while
instrument is in calibration mode.
Note that - when enabled here - there is also a
length of the DAS HOLD OFF after calibration
mode, which is set in the VARS menu (refer to
Section 7.2.11).
OFF OFF o

7.1.2. DAS PARAMETERS
Data parameters are types of data that may be measured and stored by the DAS. For
each Teledyne API’s analyzer model, the list of available data parameters is different,
fully defined and not customizable. Appendix A-5 lists firmware specific data
parameters for the T100. The most common parameters are concentrations of the
measured gas (SO
2
), temperatures of heated zones (converter, sample chamber, box
temperature…), pressures and flows of the pneumatic subsystem and other diagnostic
measurements as well as calibration data (slope and offset) for each gas.
Most data parameters have associated measurement units, such as mV, ppb, cm³/min,
etc., although some parameters have no units. The only units that can be changed are
those of the concentration readings according to the SETUP-RANGE settings. Note that
the DAS does not keep track of the unit of each concentration value and DAS data files
may contain concentrations in multiple units if the unit was changed during data
acquisition.
Each data parameter has user-configurable functions that define how the data are
recorded (refer to Table 7-3).
