at the rear panel for connection to a remote computer or other digital
communication device. Internally, there are two USB user connections
which are used for updating firmware to the PCBs. Figure 1-2 shows the
rear panel including the user connections for the standard instrument
without the auto calibration manifold.
The analyzer is set up for either 120 VAC 60 Hz or 230 50/60 Hz
operation depending on the customer’s requirements. The appropriate
power cord for your unit is included with the analyzer.

Internally, there are three isothermal chambers each separately
controlled for precise control and separation of analyzed species. In the
electronics section, internal PC boards are stacked in an assembly in an
order based on inter connectivity needs between the PCBs as well as
their association with other sub assemblies distributed within the system.
See Figure 1-3.
