The T200H/M analog output channels can be assigned to output data from any of the
40+ available DAS parameters (see Table A-6 of Appendix A.5). The default settings
for the four output channels are:

sensor options installed, DAS parameter O2CONC is assigned to output A4.

The number of DAS objects are limited by the instrument's finite storage capacity. For
information regarding the maximum number of channels, parameters, and records and
how to calculate the file size for each data channel, refer to the DAS manual
downloadable from the T-API website at http://www.teledyne-api.com/manuals/ under
Special Manuals.
While the DAS parameters available for output over via the analog channels A1 thru A4
include a vide variety internal temperatures, gas flows and pressures as well as certain
key internal voltage levels, most of the DAS parameters are related to gas concentration
levels.
Two parameters exist for each gas type measured by the T200H/M. They are generally
referred to as range 1 and range 2 (e.g. NXCNC1 and NXCNC2; NOCNC1 and
NOCNC2; etc.). These take the place of the high and low concentration ranges of
previous versions of the analyzer software. Concentrations for each range are computed
using separate slopes and offsets which are also stored via separate DAS parameters.
If an analog output channel is set to report a gas concentration (e.g. NXCNC1;
NO concentration; Range 1) it is generally a good idea to use 80% of the
x
reporting range for that channel for the span point calibration. If both available
parameters for a specific gas type are being reported (e.g. NXCNC1 and
NXCNC2) separate calibrations should be carried out for each parameter.
