triggering events.
A User-configurable list of data types to be

data point.
PERIOD
The number of reports that will be stored in
NUMBER OF
the data file. Once the specified limit has
RECORDS
been exceeded, the oldest data are over-
written to make space for new data.
Enables the analyzer to automatically report
RS-232
channel values to the RS-232 ports.
REPORT
Enables or disables the channel. Provides a

convenient means to temporarily disable a
ENABLED
data channel.
Disables sampling of data parameters while
CAL HOLD OFF
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 (Section 4.11.2.11.)

DESCRIPTION
Data parameters are types of data that may be measured and stored by the DAS. For each
Teledyne ML 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 T101. The most common parameters are concentrations of measured gases (H
and NO ), temperatures of heated zones (converter, sample chamber, box temperature...),
2
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
(Table 4-21).
