The output, labeled A3 is special. It can be set by the user (see Test Channel Output
section in the T101 Manual - PN 07266) to output many of the parameters accessible
through the <TST TST> buttons of the units Sample Display.
Output A4 is not available on the Model T102 Analyzer.
Setting the gas measurement mode on the T102 is identical to the method described in
the Setting the Gas Measurement section in the T101 Manual - PN 07266 except that the
available measurement modes are as described in the following table:

Table 6-1. T102 Gas Measurement Modes

The sample gas stream is stripped of any ambient SO
chemical scrubber, then passed through a catalytic converter that
changes the TRS present into SO
UV Fluorescence method
The sample gas stream bypasses the SO
converter allowing the only ambient SO
The switching valve alternates the gas stream between the two paths
at regular intervals allowing the instrument to measure both gases.
The following table supersedes the Analog Output Pin Assignments table in the Analog
