to be used to zero the analyzer, eliminating the need to switch external tanks.

•Overall Design.

The design of the sample system minimizes the volume of dead space, which can retain residual gas from another route or previous mode of analysis.

2.1.3 Electronics and Signal Processing

The Model 3160 analyzer has an embedded microcomputer, which controls all signal processing, input/output, and display functions for the analyzer. System power is supplied from a power supply module designed to be compatible with any interna- tional power source.

The microcomputer, a liquid crystal display (LCD), and all analog signal pro- cessing electronics are located inside a replaceable control module. A light emitting diode (LED) display is located outside the control module.
