Sample Handling Assembly:
Testing is performed in
this osmometer module. The sample handling
assembly monitors and controls the sample probe,
cooling assembly, and actuator switch.
•
Power Supply and Control Assembly:
This component
provides power to the instrument via the fused power
inlet assembly. The control PCB contains the logic to
perform osmometer tests and manage
communications with the display assembly and
barcode scanner. The USB and Ethernet ports are
mounted to the power supply and controls assembly,
and are connected to the display assembly.
•
Display Assembly:
This assembly consists of the
display PCB and the touchscreen display. It provides
the graphical user interface (GUI) used to show and
retrieve information about tests and the instrument
configuration. The USB and Ethernet port interfaces
and cables are part of the display assembly.
