3.3.1.3. Connecting Analog Outputs
The 9110T is equipped with several analog output channels accessible through a connector on the back
panel of the instrument.
Output channels A1, A2 and A3 are assigned to the NO
x
, NO and NO
2
concentration signals of the
analyzer.
The default analog output voltage setting of these channels is 0 to 5 VDC with a reporting
range of 0 to 500 ppb.
An optional Current Loop output is available for each.
The output labeled A4 is special. It can be set by the user to output any one a variety of diagnostic test
functions (see Section 5.9.4).
The default analog output voltage setting of these channels is also 0 to 5 VDC.
See Section 5.9.4 for a list of available functions and their associated reporting range.
There is no optional Current Loop output available for Channel A4.
To access these signals attach a strip chart recorder and/or data-logger to the appropriate analog output
connections on the rear panel of the analyzer. Pin-outs for the analog output connector are:
